• Resolving Multi-Path Interference in Compressive Time-of-Flight Depth Imaging with a Multi-Tap Macro-Pixel Computational CMOS Image Sensor

  Multi-path interference causes depth errors in indirect time-of-flight (ToF) cameras. In this paper, resolving multi-path interference caused by surface reflections using a multi-tap macro-pixel computational CMOS image sensor is demonstrated. The imaging area is implemented by an array of macro-pixels composed of four subpixels embodied by a four-tap lateral electric field charge modulator (LEFM). This sensor can simultaneously acquire 16 images for different temporal shutters. This method can reproduce more than 16 images based on compressive sensing with multi-frequency shutters and sub-clock shifting. In simulations, an object was placed 16 m away from the sensor, and the depth of an interference object was varied from 1 to 32 m in 1 m steps. The two reflections were separated in two stages: coarse estimation based on a compressive sensing solver and refinement by a nonlinear search to investigate the potential of our sensor. Relative standard deviation (precision) and relative mean error (accuracy) were evaluated under the influence of photon shot noise. The proposed method was verified using a prototype multi-tap macro-pixel computational CMOS image sensor in single-path and dual-path situations. In the experiment, an acrylic plate was placed 1 m or 2 m and a mirror 9.3 m from the sensor.

• A Large Effective Touchscreen Using a Head-Mounted Projector
  Yusuke Kemmoku; Takashi Komuro
  Information, Volume：9, Number：9, First page：235, Last page：235, Sep. 2018, [Reviewed]
  In our previous work, we proposed a user interface in which a user wears a projector and a depth camera on his or her head and performs touch operations on an image projected on a flat surface. By using the head-mounted projector, images are always projected in front of the user in the direction of the user’s gaze. The image to be projected is changed according to the user’s head pose so as to fix the superimposed image on the surface, which realizes a large effective screen size. In this paper, we conducted an experiment for evaluating the accuracy of registration by measuring the positional and rotational errors between the real world and the superimposed image using our experimental system. As a result, the mean absolute errors of translation were about 10 mm when the user stopped his head, and the delay was estimated to be about 0.2 s. We also discuss the limitations of our prototype and show the direction of future development.

• Multi-Aperture-Based Probabilistic Noise Reduction of Random Telegraph Signal Noise and Photon Shot Noise in Semi-Photon-Counting Complementary-Metal-Oxide-Semiconductor Image Sensor

  A probabilistic method to remove the random telegraph signal (RTS) noise and to increase the signal level is proposed, and was verified by simulation based on measured real sensor noise. Although semi-photon-counting-level (SPCL) ultra-low noise complementary-metal-oxide-semiconductor (CMOS) image sensors (CISs) with high conversion gain pixels have emerged, they still suffer from huge RTS noise, which is inherent to the CISs. The proposed method utilizes a multi-aperture (MA) camera that is composed of multiple sets of an SPCL CIS and a moderately fast and compact imaging lens to emulate a very fast single lens. Due to the redundancy of the MA camera, the RTS noise is removed by the maximum likelihood estimation where noise characteristics are modeled by the probability density distribution. In the proposed method, the photon shot noise is also relatively reduced because of the averaging effect, where the pixel values of all the multiple apertures are considered. An extremely low-light condition that the maximum number of electrons per aperture was the only 2 e − was simulated. PSNRs of a test image for simple averaging, selective averaging (our previous method), and the proposed method were 11.92 dB, 11.61 dB, and 13.14 dB, respectively. The selective averaging, which can remove RTS noise, was worse than the simple averaging because it ignores the pixels with RTS noise and photon shot noise was less improved. The simulation results showed that the proposed method provided the best noise reduction performance.

  We focus on the growing need for a technology that can achieve motion capture in outdoor environments. The conventional approaches have relied mainly on fixed installed cameras. With this approach, however, it is difficult to capture motion in everyday surroundings. This paper describes a new method for motion estimation using a single wearable camera. We focused on walking motion. The key point is how the system can estimate the original walking state using limited information from a wearable sensor. This paper describes three aspects: the configuration of the sensing system, gait representation, and the gait estimation method.

  Transactions of the Virtual Reality Society of Japan, Volume：15, Number：2, First page：173, Last page：182, 2010, [Reviewed]
  We propose a variant of the multi-touch display technology that introduces an original way of manipulating three-dimensional data. The underlying metaphor is that of a deformable screen that acts as a boundary surface between the real and the virtual worlds. By doing so, the interface can create the illusion of continuity between the user's real space and the virtual three-dimensional space. The developed system presented here enables this by employing three key technologies: a tangible and deformable projection screen, a real-time three-dimensional sensing mechanism, and an algorithm for dynamic compensation for anamorphic projection. This paper introduces the concept of the deformable tangible workspace, and describes the required technologies for implementing it. Also, several applications developed on a prototype system are detailed and demonstrated.

  This paper describes a real-time three-dimensional sensing system for applications based on feedback automation. The proposed system enables to observe a moving/deforming object at high frame rate and can acquire data in realtime. These are provided by three distinctive features, three-dimensional sensing by a single frame, high-frame-rate imaging and high-speed image processing. We also present some results of evaluation experiments. The experimental results show the advantages of our system compared with conventional approaches. Our system is expected to achieve improvements in a wide range of three-dimensional-sensing applications.

  It is difficult to measure the 3D shape of organs by Time-of-Flight technology since the human tissue is the translucent and closed environment inside the human body causing multi-path reflections. We developed the new camera to eliminate the effect of the multi-path of light reflections and scattering of the light. We also proposed the 3D reconstruction method from the camera. We developed endoscopic surgery supporting system which visualizes the inside of the organs and tracks the visualization with the deformation of the organ shape. Moreover, we applied some proposed methods to real surgery and evaluate the effectiveness of helping it.

  It is well known that biometric information can provide convenient and reliable user authentication. Recently, the application field of biometric authentication is expanding from small-scale service to wide-scale one such as big event venue. In these situations, high-speed calculation and smooth operation are required because of a large number of users. In order to apply finger vein authentication to above services, we propose a hand waving finger vein authentication system, in which a hand-waving movie is captured with a camera, and a biometric feature is obtained by synthesizing some finger vein patterns extracted from the movie. In our study, we developed a prototype system of the hand-waving finger vein authentication and evaluated the verification performance of the proposed system.

  In this reseasrch, we proposed a method of realizing object tracking and image restoration in the dark in which target motion and a reference image are simultaneously estimated using a Bayesian framework. Deblurring is performed using the motion parameters estimated from the blurred images. As a result, we realized object tracking and image restoration from simulated video images with an SNR of up to -6 dB, and real video images captured in a dark environment of less than 0.01 lx illuminance at the subject surface. In addition, we examined the optimal frame rate for image restoration and we found that a higher frame rate was better under relatively little noise while a lower frame rate was better under much noise.

  We have developed a massively-parallel visual-information-processing chip called as Vision Chip. The developed chip has shown the effectiveness of the high-speed visual feedback at the speed of 1kHz which is largely increased in the speed compared with the conventional video-rate(30Hz). The fundamental technology for such high-speed visual feedback is now being established. This technology progress allows us to enter a new phase to challenge the application development for the real world. Based on this background, in this research project, we focus on two key applications, High-speed Visual Interface and High-speed Micro Visual Feedback. High-speed Visual Interface observes human motion in real-time by using high-speed vision and realizes new man-machine interaction systems. High-speed Micro Visual Feedback observes microorganism at high accuracy by controlling a microscope based on the feedback of the high-speed vision.

  The purpose of this study is to develop a recognition-behavior integration system which can act in a flexible manner at high-speed in the real environment. Using basic technologies, such as sensory-motor integration based on hierarchical parallel architecture, ultra-high-speed recognition and motion, and distributed network processing architecture, we have developed a high-speed realtime processing system in which a large number of sensors and actuators are connected based on distributed network architecture.
  1.A high-speed vision network system with TCP/IP communication function.
  In order to track many targets which moves at high-speed in a wide area without occlusion, we have developed a distributed cooperative network system with multiple vision systems.
  2.A distributed sensor network information processing algorithm.
  We have proposed a sensor fusion processing method called DTKF (Delay-Tolerant Kalman Filter). DTKF is a method using Kalman Filter, and it has a good scalability against the increase of the number of sensors. The proposed method was verified by a numerical simulation of a target tracking task of high-speed vision sensor.
  3.A multi-high-speed visual feedback system.
  We have developed a multi-high-speed visual feedback system with multiple high-speed visions. By interpolating the lack of information using several vision systems, a 3D tracking of multiple targets which is robust against occlusion is achieved. Also, the improvement of a range of measurement and accuracy, and occlusion avoidance is achieved.
  4.Sensory-motor fusion based on hierarchical parallel processing architecture
  In order to connect a large number of sensor systems and robot systems, we have developed a parallel distributed processing system in which realtime processing systems, robot systems, and sensor systems are integrated. In the system three realtime processing systems made by dSpace Inc, are connected to each other using the CAN bus, and two robot arms, three robot hands, three high-speed vision systems (six camera heads), and other sensors (tactile sensors, force sensors, and so on) are connected with high-speed IO ports.

  Conventional manipulators are designed to control the end point position with high accuracy based on the joint angle measurement, and are not designed for high-speed control with vision sensors. Therefore, it is difficult to achieve an intellectual, high-speed task for enabling the performance of high-speed vision. And thus the speed-up of the whole visual feedback system highly depends on the speed-up of the manipulation system. We think that introducing high-speed actuator is not enough and it is important to understand the characteristics of the image processing system and the active vision, the hand system and also the design of the control system. In this sense, to achieve the super-high-speed visual servo system, we have to develop the model that describes the dynamics of all elements composing the system ; and the development of the parameter identification technique ; and the model learning algorithm. The following research are done this year :
  1.Visual servo by high-speed hand system : A high-speed multi finger hand system was developed. An algorithm to catch a falling ball and a falling column stably was proposed, and the performance of the super-high-speed visual servo was evaluated by experiments.
  2.Microorganism tracking system : A system that can stably observe a swimming paramecium was developed. The position of the pool where a lot of paramecia swim was controlled by a XY stage.
  3.Expansion of stability area of visual servo : In this research, the method of expanding the stability area was examined in consideration of the restriction with limited camera view.
  4.Composition and robustness in visual servo system : In this research, it was pointed out that the robustness of the system changes greatly by combining different structures and algorithms.
  5.Ball capture and lifting task : Ball catching and lifting experiments have been done.
