In this paper, we present an algorithm that generates high dynamic range (HDR) images from multi-exposed low dynamic range (LDR) stereo images. The vast majority of cameras in the market only capture a limited dynamic range of a scene. Our algorithm first computes the disparity map between the stereo images. The disparity map is used to compute the camera response function which in turn results in...
According to the characteristic of welding container reinforced plate and structured-light measurement theory, this paper designs an initial position locating system for container welding robot, which uses a calibration method of one CCD and lasers based on fixed in workspace vision and a sub-pixel feature extraction method of welding seam. This system with fixed image resolution can acquire the image...
A high precise mobile positioning microrobot is designed in this paper. The microrobot has macro and micro driving modes. The macro driving mode uses two smoovy motors to drive the microrobot quickly moving on a desktop in a huge range and accomplishing the first precise positioning in millimeter scale with wheels. The micro driving mode, using PZT stacks as micro driving elements and with the help...
