Problems solved by technology

However, in related technologies, when performing object detection on an image, most of the entire image is input into the detection network, and the detection network needs to perform detection operations on the entire image, and the detection efficiency is low; at the same time, static objects in the image will interfere with the detection network Detect moving objects, such as misdetecting trees as pedestrians, which also affects the detection accuracy

Abstract

The invention provides a moving target detection method and device, and electronic equipment. The method comprises the following steps: determining a current frame image and a specified frame image corresponding to the current frame image from a to-be-detected video according to the sequence of each video frame in the to-be-detected video; determining a detection area of the moving target according to the pixel value difference of the corresponding pixel points between the current frame image and the specified frame image; inputting the image data corresponding to the detection area into a preset target detection model, and outputting an initial detection result corresponding to the detection area; and mapping the initial detection result to the current frame image to obtain a final detection result. According to the embodiment of the invention, the rough detection area of the moving target can be obtained through the pixel value difference between the two frames of images, thereby reducing the detection range of the target detection model, and improving the detection efficiency. Meanwhile, most static targets are eliminated from the detection area, so that the interference on dynamic target detection of the model is reduced, and the detection accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to a method, device and electronic equipment for detecting a moving target. Background technique [0002] For most detection tasks, people tend to only detect moving objects in images, such as pedestrians, vehicles, etc., and are not interested in static objects such as trees and street lights, which usually only occupy a part of the image. However, in related technologies, when performing object detection on an image, most of the entire image is input into the detection network, and the detection network needs to perform detection operations on the entire image, and the detection efficiency is low; at the same time, static objects in the image will interfere with the detection network Detecting moving objects, such as misdetecting trees as pedestrians, also affects the detection accuracy. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the e...
