Repeated action recognition method, device, medium and equipment

Abstract

The embodiment of this specification discloses a repetitive action recognition method, device and electronic equipment. The method includes inputting each frame of image into a pre-trained operation area recognition model and operator recognition model to obtain an operation area detection frame and an operator detection frame. Screen the operators in the operating area, input the screened images into the pre-trained body recognition model, obtain the operator's torso information and arm information, and perform single action recognition on the operator in each operating area based on the torso information and arm information ; Calculate the time when there is a single action in the operation area with the same serial number in different frame images of the video to be tested. When the time of the single action is greater than the time threshold, it is judged that the operator in the operation area has performed a repeated action. It helps to improve the accuracy of repetitive action recognition, effectively supervise non-standard repetitive actions, improve the efficiency of food safety supervision, and reduce the cost of manpower and material resources for enterprises.

Description

technical field [0001] This description relates to the technical field of computer vision, and in particular to a repetitive action recognition method, device, medium and equipment. Background technique [0002] Schools, enterprises, factories and other canteens have a large number of diners. Food safety involves all aspects. Not only must the source of food materials be reliable and the processing process is safe and hygienic, but if the tableware is not cleaned cleanly, the remaining food residues will produce harmful substances and breed harmful bacteria. It will pose a threat to the health of dining employees in schools, enterprises, and factories, so the disinfection and cleaning of tableware cannot be ignored. [0003] The existing tableware cleaning for canteens generally adopts manual cleaning. Due to the large flow of people in schools, enterprises, factories and other canteens and the concentration of meal time, many people often send the tableware after meals to t...

Problems solved by technology

[0003] The existing tableware cleaning for canteens generally adopts manual cleaning methods. Due to the large flow of people in schools, enterprises, factories and other canteens and the concentration of meal time, many people often send the tableware after meals to the plate recycling place at the same time. The stacking of disks puts a lot of pressure on the staff to recover and clean. Once the staff is slack and irresponsible, safety problems are prone to occur. Although monitoring is installed in the cleaning room, the current video surveillance return visit cannot be realized through random inspection. The performance of staff on the job is fully supervised, and there are great loopholes and potential safety hazards
