Abstract

The invention discloses a panoramic video structuring method. Including: acquisition of panoramic data, image training for panoramic data, global search and scanning using a model that is effective for distorted images after training, frame the area where the target of interest appears, use the rectangular frame information to intercept the image of interest, distortion correction, use traditional The video structuring algorithm is used to conduct further structural analysis on the distortion-corrected images to obtain structured data of the panoramic video. The present invention can realize panoramic scanning without dead angle in the scene through a panoramic video acquisition device, and realize structural analysis of video content without additional video structuring equipment or synchronization equipment, effectively reducing The redundant information is convenient for subsequent storage and data analysis and indexing; by scanning and searching the original picture, the workload of global distortion correction for the original picture is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of video structuring, in particular to a video structuring method, in particular to a panoramic video structuring method. Background technique [0002] At present, video intelligent recognition and analysis equipment has special requirements for the lens of its video / image input source. One of the important restrictions is that the field of view of the lens cannot exceed 90°. This is mainly because the imaging lens exceeds 90°. The distortion of the imaging edge will bring serious loss to the recognition accuracy of the algorithm. Ordinary video structured cameras have the disadvantage of limited field of view and cannot completely record and capture all the complete information of people and cars in the scene. At present, the demand for no-dead-angle monitoring in the market is becoming more and more prominent. More and more monitoring equipment have a lens field of view angle greater than 100°, an...
