The present invention relates to a target detection method and device. The method includes: preprocessing the current frame image to obtain the current frame grayscale image; obtaining a dynamic background and a reference background; Perform background difference processing on the background to obtain a first difference image; perform image segmentation processing on the first difference image, and judge whether there is a sudden change in illumination, and if so, use the reference background to perform dynamic background update; Perform background difference processing and image segmentation processing on the grayscale image and the updated dynamic background to obtain a dynamic foreground image; judge whether there is a false foreground in the dynamic foreground image, and if not, perform image post-processing on the dynamic foreground image to obtain sports goals. The object detection method and device provided by the present application have small calculation amount, strong ability to deal with sudden changes in illumination, and controllable determination of stationary objects.
Description
technical field [0001] The present application relates to the field of image detection, in particular to a target detection method and device. Background technique [0002] With the continuous advancement of digital image processing technology, video surveillance has already developed from analog surveillance to digital surveillance, and from conventional surveillance to intelligent surveillance. Conventional monitoring implements image analysis through the human brain, while intelligent monitoring automatically implements image analysis functions through computers. Image analysis refers to the detection, tracking, identification, behavior analysis and other processing tasks of the target of interest in the video image. This technology combines computer vision, pattern recognition, artificial intelligence and other technologies, and is often called image intelligent analysis. Intelligent image analysis can identify abnormal events that cannot be detected by sensors, and im...
