Video completion method

The invention provides a video completion method, which is characterized in that a missing video sequence with content missing is completed by reconstructing a three-dimensional scene, and comprises the following steps: 1, identifying a depth map of each frame in the missing video sequence through a preset depth map network; 2, recognizing a relative camera pose between every two adjacent frames in the missing video sequence through a preset pose network; step 3, based on the depth map and the relative camera pose, performing fusion of the depth map by using a truncated symbol distance function so as to construct a three-dimensional scene corresponding to a video background in the missing video sequence; step 4, projecting the three-dimensional scene into the missing video sequence by using the relative camera pose and the camera internal reference so as to complement the defect area of each frame to obtain a complemented video sequence; and step 5, performing secondary completion on the completed video seque
