Above all, we pointed out that the basis of the calibration algorithm based on the grid points is the matrix, which indicates the mapping relationship between the target surface and the image surface. But to our disappointment, it is the correspondence problem of the calibration points that exists in the current way to calculate it. Therefore, the fiducial marker system is used for reference here,...
Solving visual features' correspondence and dealing with missing data are two factors of limitations for points registration techniques. To tackle this problem, we conceived a pattern, primarily designed for structured lighting vision systems, which may also be used for camera calibration purposes. The pattern design previously presented provides a huge of benefits. Among them, we firstly present...
This study presents a low-cost scanning system for acquiring 3D geometry and texture information of large objects and for performing multi-scanning patch registration to obtain a whole realistic 3D model. The proposed system is composed of a line-stripe laser and a color CCD camera. The scanning processes consist of three steps. In the first step, the 3D depth information of the scanned object is...
