An intracorporeal optical tracking system for minimal invasive (MIS) surgery is proposed. MIS has been widely used in laparoscopic surgery since 1980s. Its advantages include small surgical cuts and short recovery time. However, because of the limited workspace and narrow view, MIS is more complicated and costs more time than open surgery. Therefore, the image-guided system plays an important role...
A 1920 1080 160 object viewpoint recognition system-on-chip (SoC) is presented in this paper. The SoC design is dedicated to wearable vision applications, and we address several crucial issues including the low recognition accuracy due to the use of low resolution images and dramatic changes in object viewpoints, and the high power consumption caused by the complex computations...
In this paper, we proposed a novel and simple gaze calibration procedure, namely Pattern Voting Scheme (PVS), for reducing the computing complex. The proposed method doesn't require multiple spatial coordinates to estimate the inner and outer parameters of the camera and without regard to the evaluation of accuracy. The iris location can be determined easy by using the voting weight. The PVS is a...
In order to ensure the surface figure of the pointing mirror (460mm long, 290mm wide) in spaceborne remote sensing camera, Silicon Carbide was selected as the mirror material. The form of composite triangular and rectangular and the combination of open and closed back was explored in the lightweight design. A new kinematic mount and flexible structure in axis is used to hold the mirror around the...
