Embodiment Construction

[0016] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] Use computer vision technology to judge whether there are pedestrians in the image or video sequence and give precise positioning.

[0018] Collect camera technology, use mask rcnn model to accurately locate production line workers, and calculate the total working hours of all people, mask rcnn is not yet real-time, about 5fps per second, so that every frame in the recognized video will appear, followed by Compared with the actual picture, there is a delay. Multi-threading technology is used to allow the camera to recognize the latest frame every time. We can calculate the working hours through the recognition time and the number of people. Because we don’t ne...

Abstract

The invention discloses a method and system for calculating man-hour through a camera. The method comprises the following steps: aligning a built monitoring camera with a production line worker on a monitoring production line; improving the trained maskrcnn model, and only identifying production line workers; calling a camera through opencv, and identifying the latest frame in the video by using a maskrcnn model; and calculating labor hours according to a video identification result. According to the method and the system for calculating the man-hour through the camera, accurate production line worker positioning and man-hour calculation can be realized.

Description

technical field [0001] The invention relates to the technical field of pedestrian detection, in particular to a method and system for calculating man-hours through a camera. Background technique [0002] For cost considerations, the warehouse calculates the effective working hours of employees on a production line instead of rough calculations through punch cards. Apply pedestrian detection technology to warehouse monitoring, and automatically calculate effective working hours, which is fast, convenient and accurate. At present, the cameras on the market can count the number of pedestrians, but not the time of pedestrians, so we need to borrow cameras to calculate the working hours through pedestrian detection technology. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and system for calculating man-hours through a camera, which can realize accurate positioning of production line workers and calculation...
