Problems solved by technology

This method needs to obtain a large amount of sample data in advance to achieve a good recognition effect, but it may not be possible to obtain a large amount of data in the implementation; in addition, it can only recognize the specific target occluders that have been set in advance, and other types of occlusions that appear Objects cannot be identified, resulting in very limited applicable scenarios

Embodiment Construction

[0024] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0025] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0026] Aiming at the deficiencies in the existing automatic detection method for foreign object occlusion of instrument equipment, the present invention discloses an automatic detection method for instrument equipment occlusion with faster processing speed, better recognition effect and wider application scenarios. This method does not need to predict the type of occlusion in advance, and can efficiently and accurately obta...

Abstract

The invention discloses a method and system for detecting whether foreign matter shielding exists in instrument equipment, and the method comprises the steps: marking a key region in an instrument equipment template image, and extracting a corresponding key region from an image of instrument equipment to be detected; determining the standard deviation of the key area of the instrument equipment to be detected and the standard deviation of the key area of the instrument equipment template image; comparing the value of the standard deviation of the key area of the instrument equipment to be detected with a first threshold value and a second threshold value, wherein the first threshold value and the second threshold value are both related to the value of the standard deviation of the instrument equipment template image. If the value of the standard deviation of the key area of the instrument equipment to be detected is smaller than the first threshold value or larger than the second threshold value, it is judged that foreign matter shielding exists in the key area of the instrument equipment to be detected. According to the method and system for detecting whether the instrument equipment is shielded by the foreign matter, the processing speed is higher, the recognition effect is better, and the use scene is wider.

Description

technical field [0001] The invention relates to the technical field of intelligent identification of instruments and meters, in particular to a method and system for detecting whether an instrument is blocked by a foreign object. Background technique [0002] With the development of intelligent identification technology for instruments and meters, in the fields of electric power, finance, chemical industry, machinery and electronics, more and more instruments and equipment are identified and monitored through cameras to obtain images or video information, which requires intelligent identification systems. Automatic detection of working status and alarm for abnormal situations. If the identified instrumentation equipment is blocked by human operation or unexpected foreign objects, the automatic identification system cannot effectively detect the status of the instrumentation equipment, which will adversely affect production work. Therefore, it is of great practical significa...
