Moving target detection method and device, electronic equipment and storage medium

Abstract

The invention provides a moving target detection method and device, electronic equipment and a storage medium, and relates to the technical field of image processing. The method comprises the following steps: obtaining a first frame image and a second frame image which are adjacent and a rotation matrix and a translation matrix between the first frame image and the second frame image, the first frame image and the second frame image comprising the same moving target; Extracting a plurality of first feature points from the first frame image; Determining a plurality of second feature points corresponding to the plurality of first feature points from the second frame image according to the second frame image and the plurality of first feature points; Calculating a plurality of distances between the plurality of second feature points and a plurality of corresponding polar lines according to the rotation matrix and the translation matrix, wherein the plurality of corresponding polar lines are a plurality of polar lines of the plurality of first feature points on the second frame image; Screening out a plurality of third feature points on the moving target according to the plurality of distances; And detecting and obtaining a moving target according to the plurality of third feature points. According to the invention, the data calculation amount and the moving target detection stepsare reduced.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a detection method, device, electronic equipment and storage medium of a moving target. Background technique [0002] The shooting of moving objects is a common shooting scene, such as in sports competitions, shooting the posture of athletes in fierce competition; in animal photography, recording the real scene of animals running. Shooting people or objects moving at high speed requires professional shooting skills and rich experience. However, many users usually do not have professional shooting knowledge, and the photographed works are not satisfactory. [0003] In related technologies, the background difference method or object segmentation method can be used to identify moving objects. The background difference method is a pixel-level background modeling and foreground detection algorithm. The core idea is the update strategy of the background model. S...

Problems solved by technology

However, when the background difference method is used to identify moving objects, the background model needs to be created and initialized, and the background model needs to be updated. Moreover, the background difference method can only recognize moving objects in images collected by fixed cameras.
