Embodiment Construction

[0052] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0053] Such as figure 1 As shown, the present invention provides a three-dimensional reconstruction texture restoration method based on window interpolation, which is suitable for fast and efficient image defect repair of sequence pictures under different viewing angles, including the following steps:

[0054] Step a. For the N background sequence pictures (including complete and defective pictures) after removing foreground obstacles under different viewing angles, select one of the defective pictures to be repaired as the reference picture, and the other pictures are used as reference pictures. Form a group of picture pairs with each reference picture respectively, arrange the photo pairs in ascending order according to the distance between the reference picture and the reference picture, and perform steps b to f for each photo pair in sequence; ...

Abstract

The invention discloses a window interpolation-based three-dimensional reconstruction texture recovery method. For the problems that a complete point cloud of a background cannot be reconstructed and a complete map texture cannot be obtained due to shielding of a foreground by a barrier in a sequence image-based background three-dimensional reconstruction process, through sequence image comparison, any defective background picture is effectively recovered, so that the purpose of reconstructing the complete point cloud is achieved. The method mainly comprises the steps of firstly performing picture grouping on defective background pictures under different view angles, and for each picture pair, unifying the picture pair under the same view angle by use of image transformation; and then performing operations of image overlapping region calculation, to-be-repaired defective pixel point locating, defective pixel point filling, boundary line removal and the like to finish picture repair. According to the method, image defect repair can be quickly and efficiently performed for sequence images under the different view angles.

Description

technical field [0001] The invention relates to a three-dimensional reconstruction texture restoration method based on window interpolation, which belongs to the field of image processing. Background technique [0002] In the process of background 3D reconstruction based on sequential images, the following three problems will be caused due to the occlusion of foreground obstacles: (1) the complete background point cloud cannot be reconstructed; (2) the reconstructed point cloud is impure and not The pure background point cloud will also contain the point cloud of obstacles; (3) It is impossible to obtain a complete background texture map. In order to solve these problems, a direct and effective method is to separate the foreground obstacles in the sequence images from the background, and then use the image restoration method to restore the completeness of each picture caused by the obstacle, and then use these complete Sequence background images for background 3D reconstruc...
