Embodiment Construction
[0050] The invention provides a fast, reliable, practical and convenient three-dimensional reconstruction method, which can be applied to an online three-dimensional detection system for fabric defects and can make up for the defects of two-dimensional defect detection technology.
[0051] The 3D reconstruction method described is as figure 1 shown, including:
[0052] The BCCSL (Binocular Camera Color Structure Light) method (proposed by the present invention) for obtaining the three-dimensional coordinates of the fabric "skeleton", which can obtain the three-dimensional data information at the projection position of the light bar;
[0053] The SFTS (Shape From Two Shading) method (proposed by the present invention) for obtaining fabric "detail" information, which can obtain three-dimensional data information other than the projected position of the light bar.
[0054] figure 1 The technical route of the 3D reconstruction shown is: use the BCCSL method to extract the fabric...
