The present invention relates to a method for matching camera image data for generating a 3D surround view, the method comprising the steps of: calibrating each of multiple pieces of image data by using a displacement value between common feature points which are overlapping feature points between different pieces of image data; and generating panoramic image data in which the multiple pieces of image data are matched, by using the calibrated image data.

METHOD FOR GENERATING 3D AROUND-VIEW FOR VEHICLE, AND DATA ANALYSIS METHOD FOR RETRIEVING VIDEO INFORMATION GENERATED USING SAME
The present invention relates to a method for generating a 3D around-view for a vehicle and a data analysis method for retrieving video information generated using same. The data analysis method for retrieving video information, executed by a processor of a server, comprises the steps of: separately recognizing, by frame, each of a plurality of pieces of first video data; training an inference model by setting, as an input value, each frame of the first video data and setting, as an output value, extraction information for each frame; collecting a plurality of pieces of second video data through web crawling in a plurality of search engines; and generating a database for the second video data by using the inference model.
G06F 16/783 - Retrieval characterised by using metadata, e.g. metadata not derived from the content or metadata generated manually using metadata automatically derived from the content
