In this paper, a Stereo Tracking Dataset is proposed for evaluating binocular tracking algorithms. The dataset contains stereoscopic videos which are collected by our mobile platform in different scenarios and videos that are available publicly. All sequences are carefully synchronized and rectified, and the ground truth of object is annotated by authors. Both raw and processed sequences are provided...
In this paper we consider the inspection of surface flaws in large aperture optical element. A high efficiency and precision instrument is proposed which contains two kinds of imaging systems. One is dark-field imaging system (DFIS) constructed by line scan camera with 10μm resolution. The other is bright-field imaging system (BFIS) constructed by microscope with 1μm resolution. Considering the small...
Fisheye camera is finding increasing number of applications in robotic vision, visual surveillance, and other fields. But the use of super-wide angle fish-eye lenses causes strong distortions in the resulting images. A method for the correction of fisheye distortion using only single images and linearity of imaged objects is presented. Spherical projection is a simple and effective method to transform...
A simple binocular visual equipment is designed in this paper, which is mainly composed by two CCD cameras and four stepping motors. Firstly, the two cameras' initial location is determined based on rough location by moving to the limiting position, and precise location by driving the image center aligning with fitted ellipse center. Then, the transformation matrix between coordinate systems of motion...
In this paper, we introduce an improved version of DAISY descriptor algorithm, which is used for high-quality image keypoint matching. Since DAISY descriptor algorithm has many prominent advantages but lacks the ability of handling large in-plane rotation, we thus construct our Rotation-Invariant DAISY descriptor to effectively settle this shortcoming. The matching results of our scheme can be also...
3D reconstruction has a long history, few workable reconstruction systems are available although many magnificent theories and algorithms are reported in literature. In this paper, a 3D reconstruction system for indoor scenes with a rotating platform is reported, including its key components such as system calibration, feature matching and 3D reconstruction. Experimental results show that this system...
