Embodiment 1

[0050] Embodiment 1 provided by the present invention is an embodiment of a method for identifying, judging and guiding a worker's work step specification provided by the present invention, and this embodiment includes:

[0051]Step 1: Obtain a video of a worker performing a standard operation, and determine the threshold range of the feature value of the image of the monitoring area corresponding to the standard operation according to the video frame.

[0052] Specifically, senior operators can complete standardized steps on the production line in accordance with the regulations. The operations include assembly, testing, and spraying. The process engineer selects the operation (assembly, testing, spraying, etc.) area as the monitoring area, and conducts video Play after recording. After defining the difference between standard jobs and invalid jobs, obtain the parameters for calculating the thresholds corresponding to work steps, and determine the thresholds for the feature va...

Embodiment 2

[0076] Embodiment 2 provided by the present invention is an embodiment of a system for identifying, judging and guiding a worker's work step specification provided by the present invention, such as figure 2 Shown is a structural block diagram of an embodiment of a system for identifying, judging, and guiding a worker's work step specification provided by the present invention, consisting of figure 2 It can be seen that an embodiment of a system for identifying, judging and guiding a worker's work step specification provided by the present invention includes a video stream receiving module 1, a client configurator module 2, a video stream analyzing module 3, a work step guiding client 4 and a main control Machine 5. The video stream receiving module 1 , the client configurator module 2 , the video stream analyzing module 3 and the work step guidance client 4 are respectively connected to the main control computer 5 through communication.

Abstract

The invention relates to a worker operation step specification identification determination and guidance method and system, and the method comprises the steps: 1, obtaining a video of a worker for standard operation, and determining the threshold value of the feature value of an image of a monitoring region corresponding to the standard operation according to a video frame; 2, acquiring a real-time worker operation video, and judging whether the characteristic value of the image of the monitoring area in the real-time worker operation video frame exceeds the threshold value or not; and 3, carrying out corresponding step prompt and / or information prompt according to whether the characteristic value exceeds the threshold value or not. Operation guidance is carried out through video monitoring and step prompting, the problem of operation errors is effectively prevented, the yield is improved, the problems that in the prior art, paper operation guidance books are low in efficiency and cannot carry out abnormity reminding are solved, and good processing habits of new workers can be established by continuously carrying out standard step comparison in a special training system.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to a method and system for identifying, judging and guiding a worker's work step specification. Background technique [0002] In the prior art, the production workers in the workshop operate according to the paper operation instructions, but the traditional paper instructions cannot intuitively instruct the workers how to work, and they cannot detect whether each step of the workers is carried out according to the specifications. . [0003] At the same time, due to the complexity of the operation, higher requirements are placed on the operating skills and attention of the operators. During the operation, workers will have problems such as unskilled operation and disordered work steps, which will not only affect work efficiency, but also reduce product quality. , There may even be artificial injury accidents, so it is necessary to have a set of work step guidance and preventi...
