Abstract:

3D reconstruction technology of object surface has the widespread application in many domains. In the process of reconstructing object surface based on images, stereo matching from different images is the most important and difficult problem in 3D reconstruction. To solve the problem and reconstructing object surface quickly, we use projector to project structured light on 3D object. We get good active clue feature in images by using improved Canny edge detection algorithm, thinning algorithm and correction algorithm. We propose an image matching algorithm based on image characteristic. A system of 3D modeling is implemented using sequence images. The system obtains the 3D data in fast speed and good precision.
