Abstract: An accurate subject distance can be calculated on the basis of a camera captured image even in a case where the attachment angle of a camera is deviated. An image captured with a camera having a wide-angle lens is input to perform distortion correction and generate a corrected image. Moreover, the inclination of a vertical object in the real world in the corrected image is calculated. The deviation angle of the camera depression angle of the camera is calculated on the basis of the inclination of the vertical object. An object distance calculation image is generated in consideration of the camera depression angle deviation angle. The distance of an object included in the camera captured image is calculated from the object distance calculation image.

Abstract: A method for segmenting a camouflaged object image based on distraction mining is disclosed. PFNet successively includes a multi-layer feature extractor, a positioning module, and a focusing module. The multi-layer feature extractor uses a traditional feature extraction network to obtain different levels of contextual features; the positioning module first uses RGB feature information to initially determine the position of the camouflaged object in the image; the focusing module mines the information and removes the distraction information based on the image RGB feature information and preliminary position information, and finally determines the boundary of the camouflaged object step by step. The method of the present invention introduces the concept of distraction information into the problem of segmentation of the camouflaged object and develops a new information exploration and distraction information removal strategy to help the segmentation of the camouflaged object image.
