Abstract:

Aimming at the phenomeon that the 3D model, which is obtained by the 3D reconstruction algorithm based on depthmapfusion, is easily influenced by depth information error, a binocular stereoview 3D reconstruction algorithm based on contour extraction and depth screening is proposed. A standard checker board is adopted to calibrate the binocular 3D reconstruction system. Canny operator is used to detect the boundary of the target object, and morphological corrosion andexpansion methods are comprehensively used to extract the continuous boundary in a specified direction.On this basis,the depth information of the target object is filtered and interpolated in order to calculate the continuous depth value.The results show that, compared with the conventional 3D reconstruction algorithm, the target object of this algorithm has higher surface integrity, and the background hot pixels surrounding the target object are removed.
