“…Although such systems have greatly improved in terms of the theory, algorithms, and practical applications of image processing, core technologies of computer vision still require breakthroughs and innovation. For instance, if a leaf falls on a moving car, computer vision should not mistake the leaf as an obstacle and put the car on break or turn it around [1][2][3][4][5].…”

This study proposes a method for using stereo vision and face recogonition. The method differs from the feedback detection method used in sensors in general. The method disregards unimportant environmental changes and improves the overall performance of the recognition and tracking functions. Dual-CCD cameras on the visual system are used to capture images of faces. Through image preprocessing, determination of the moving target, and the position of the target center, the image is matched with the sample image to allow the robot to recognize and track stereo objects visually. The robot can recognize and track faces. And, the system also sends the images to a remote computer by wireless. A scheme is proposed to enhance the authentication messages by hash function in wireless communications. Since the proposed scheme provides an encryption function, it improves the authentication for wireless communications.

“…Their general purpose application is limited. Background subtraction scheme [21,22] used a pre-defined environmental background model stored in database for comparing with current captured image. Subtracting the background image model from current extracted image information can obtain the coming or moving object.…”

Usually, a humanoid robot has two arms and stereo vision system to execute human daily actions. It has complicate mechanism and mechatronics control system structure. The hardware control structure should be planned ingeniously to execute the complicate computation of 3D image processing and manipulate a multi degree of freedom dual arms motion control, especially for mobile robot system. Here a 7 DOF dual arms robot with FPGA hardware control structure and a digital signal processor (DSP) based CMOS stereo vision system are designed and built in our lab. The intelligent fuzzy sliding mode control strategy is employed to establish the visual guided robotic motion control software. This low cost humanoid robotic system has compact control structure and mechanism integration for mobile application purpose. Object detecting and tracking schemes in 3D space were developed for locating the target position and then guided the robot arm to pick and place objects or track the specified moving target. Experimental results show that this delicate robotic system has basic humanoid function.

“…The current extracted image is used to compare with last captured image without input background information for comparison. The difference between those two images is defined as the zone of moving object location [12,17]. In addition, Chen and Yang [18] proposed a robust object tracking method via a spatial bias appearance model learned dynamically in video.…”

Currently, most of the stereo vision systems are constructed on PC-based or multi-CPU combination structures with two CCD cameras. It is difficult to be applied in movable plants for stand-alone requirement. Due to electronic technology development, the complementary metal-oxide semiconductor (CMOS) image sensor has been widely used in a lot of electronic commercial products and the digital signal processor (DSP) operation speed and capacity are good enough for stereo vision system requirement. Here, a new stereo vision platform is designed with TMS320C6416 DSK board integrated with two CMOS color image sensors for detecting and locating moving objects. The data communication interface, system monitoring timing flow, and image pre-processing software programs are developed, too. This system can be used to detect and track any moving object without object color and shape limitations of previous study. Experimental results are used to evaluate this system's dynamic performance. This low cost stereo vision system can be employed in movable platform for stand-alone application, i.e., mobile robot.
