Problems solved by technology

[0004] However, in such an image recognition method, the extraction of image features requires a huge amount of calculations, and because most of the images taken by the camera components remain static, it often results in a waste of computing resources. At the same time, through image features, comparing objects in different images It is difficult to guarantee the real-time performance of image recognition, especially for high-speed moving objects, the positioning effect is poor

Abstract

The embodiment of the invention discloses a moving object positioning method and device, electronic equipment and a storage medium. The method comprises the steps: acquiring event flow information through a dynamic vision sensor, and acquiring image information through a target camera shooting assembly; sampling the event flow information according to a preset sampling period to obtain a sampling event frame, and determining a prediction position area of a moving object in the sampling event frame according to the event flow information; and determining a matched positioning area in the image information according to the predicted position area. According to the technical scheme disclosed by the embodiment of the invention, the prediction position area of the moving object in the sampling event frame is determined after the event flow information is obtained through the dynamic vision sensor, and the matched positioning area is determined in the image information of the target camera component, so that the positioning efficiency of the moving object is improved; and particularly, the detection real-time performance of the high-speed moving object is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image recognition, and in particular, to a positioning method, device, electronic equipment, and storage medium for a moving object. Background technique [0002] With the continuous advancement of science and technology, image recognition technology has developed rapidly and is widely used in various fields. Among them, the positioning of high-speed moving objects in images has become an important branch of image recognition technology. [0003] In the prior art, feature extraction is usually performed directly on the global image for the video image acquired by the camera component, and a moving object is located in the image according to the extracted image feature. [0004] However, in such an image recognition method, the extraction of image features requires a huge amount of calculations, and because most of the images taken by the camera components remain static, it often resu...
