Abstract

On the basis of the principle of SIFT algorithm, this paper constructed a completely new algorithm framework. The algorithm used FCN and BP neural network to comprehensively consider the semantic segmentation and image gray level co-occurrence matrix of the main target of image to achieve adaptive feature point detection range and quantity adjustment. And it used the offset stability of camera position to eliminate false matching during feature point matching. In the meantime, it optimized the pose recovery results by using graph-based optimization nonlinearity and obtained a more accurate camera pose. Finally, comparing with the existing mainstream algorithms, the experimental results verify the effectiveness of the proposed algorithm, the improvement of the scene-adaptive degree of feature points detection, the matching precision of feature points, the precision of posture recovery, and the better efficiency of three-dimensional reconstruction.
