Aiming at the problems of non-overlapping regions between adjacent images, excessive black linear noise, and low image contrast in the process of glass internal texture image stitching, a new method for stitching internal texture images of glass with non-overlapping regions is proposed. First, the images are preprocessed, which includes the region of interest extraction, image correction, non-local means denoising, multi-scale detail enhancement and so on. Then, feature points are extracted using image projection and updated by the Shi-Tomasi algorithm. Finally, the background parts at the stitching boundaries are removed, and image registration is performed based on translation transformation to achieve the stitching of internal texture images of glass with non-overlapping regions. Experimental results show that the proposed method effectively addresses the problem that non-overlapping region between adjacent images leads to the difficulty of stitching, achieving high-quality image stitching with an accuracy of 95.08%.
