Title:
METHOD AND APPARATUS FOR SYNTHESIZING PANORAMIC VIDEO, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/192358
Kind Code:
A1
Abstract:
Provided in an embodiment of the present application are a method and apparatus for synthesizing a panoramic video, and an electronic device. The method for synthesizing a panoramic video comprises: acquiring each original video respectively captured by two fisheye cameras in a dual-fisheye device; searching for a pre-established panoramic synthesis mapping table, and generating each video to be spliced corresponding to each original video and a splicing relationship between videos to be spliced, wherein the panoramic synthesis mapping table is obtained by respectively processing each external parameter calibration image on the basis of an external parameter of the fisheye cameras calibrated in the external parameter calibration images collected by each fisheye camera and an internal parameter of the fisheye cameras calculated according to each external parameter calibration image; and according to the splicing relationship, splicing each video to be spliced, and synthesizing the panoramic video. By means of the present solution, the hardware cost for synthesizing the panoramic video may be reduced, and the efficiency of synthesizing the panoramic video may be improved.
