Abstract

An embodiment of the present application provides a tracking target-based search method, device, and hand-held camera, which includes determining a first search algorithm corresponding to a first search algorithm in a first image frame according to effective identification information of a tracking area corresponding to a tracking target. area, and use the first search algorithm to search in the first search area; and according to the effective identification information of the tracking area corresponding to the tracking target, determine at least one second search area corresponding to the second search algorithm in the second image frame, and A second search area is searched using a second search algorithm. Thereby, the tracking accuracy of the tracking target can be improved, and the probability of losing the tracking target can be reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of computer vision, and in particular to a search method, device and handheld camera based on tracking targets. Background technique [0002] Object detection and tracking is a direction that has developed rapidly in the field of computer vision in recent years. With the development of visual processing technology and artificial intelligence technology, household handheld cameras can also be used to track the target to be photographed, and perform operations such as object recognition and scene recognition according to the target to be photographed, so that users can classify the photos or videos taken and management, and other subsequent automated processing operations. [0003] However, there is a problem in the current single-target tracking algorithms, that is, when at least one of the target's shape, lighting conditions, scene, and position changes, it will seriously affect ...
