Aiming at the problem of large information loss in the feature point extraction algorithm based on gray image in visual slam, the information loss of RGB image transformed into gray image is quantitatively described according to the information entropy measurement of image, and a feature extraction algorithm based on information entropy evaluation is proposed. The feature descriptor is constructed according to RGB three channels to realize the fusion of features at the pixel level, which provides a basis for feature matching Reliable basis. |
