Problems solved by technology
[0003] There are various instrument locations in the factory workshop, some are embedded in the instrument, and some require manual reading and recording data at certain moments, which cannot be wrapped
According to actual investigations, more than half of the instruments in places where safety monitoring is required, such as pharmaceutical factories and chemical plant coating workshops, cannot be monitored by fully packaged detection devices. However, if an open device is used for monitoring, it will be subject to various external Unfavorable conditions will cause deviations in the test results and fail to achieve the purpose of safety production monitoring

The invention discloses an anti-interference method for an instrument visual reading on-line monitoring system in a complex environment, and the method comprises the following steps: receiving image data returned by a sensor, carrying out the preprocessing of an image, and obtaining a needed grey-scale map; extracting the edge of the image by using a canny operator to obtain an edge image; detecting the image features by using Hough transform, and respectively extracting a circle representing a dial plate and a straight line representing a pointer in the target image to obtain all circular edge and straight line edge data; screening the circular edge to obtain a target circular edge representing the dial plate; screening straight line edges to obtain target straight line edges representingpointers; intercepting an image around the pointer to obtain an image of an area around the pointer; comparing the area of the pointer region with the distribution characteristics of the grey level histogram, and judging whether shadow interference exists or not to obtain a shadow detection result; and removing the interference of the shadow part to obtain an image without shadow interference.
Description
[0001] This patent application was submitted on December 27, 2018 with the application number 201811607738.9, and the name is a divisional application for an anti-interference algorithm for an online monitoring system for instrument visual readings in a complex environment. technical field [0002] The invention belongs to the technical field of detection instruments, and in particular relates to an anti-interference method for an online monitoring system for instrument visual readings in complex environments. Background technique [0003] There are a variety of instrument locations on the factory floor, some are embedded in the instrument, and some require manual reading and recording data at certain moments, and cannot be wrapped. According to actual investigations, more than half of the instruments in places where safety monitoring is required, such as pharmaceutical factories and chemical plant coating workshops, cannot be monitored by fully packaged detection devices.
