Abstract

The invention discloses a power plant instrumental equipment image identification method and a power plant instrumental equipment image identification system based on handheld intelligent patrol inspection. The power plant instrumental equipment image identification method comprises the steps of: 1) acquiring a high-quality instrumental equipment state image by utilizing an image acquisition method based on two-dimensional code matching quickly and precisely, acquiring position and type information of patrol inspection instrumental equipment, and correcting positional deviation of the instrumental equipment state image; 2) acquiring a type of instrumental equipment according to the type information obtained in the step 1), selecting corresponding image identification algorithms according to different instrumental equipment types, analyzing and processing the instrumental equipment state image, and identifying state of the equipment. The power plant instrumental equipment image identification method and the power plant instrumental equipment image identification system adopt an image positioning and matching algorithm based on two-dimensional codes, and the two-dimensional codes can be used for determining position information of the patrol inspection instrumental equipment as well as type information of the patrol inspection instrumental equipment, thus the problems caused by complicated field environment of a substation and poor precision of handheld equipment can be solved, and the method and the system have high robustness and practicality.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and system for image recognition of instrumentation equipment in power plants based on hand-held intelligent inspection. Background technique [0002] At present, the daily operation of most power plants in my country generally adopts the method of manual inspection, and the equipment faults of each equipment in the power plant are sequentially checked through manual meter reading and recording. Due to the large number, variety and wide distribution of equipment in the power plant, the workload of manual inspection is heavy, and the inspection time is very long, so the labor cost of manual inspection is high and the effect is difficult to guarantee. In order to solve the problem of manual inspection, autonomous inspection equipment is one of the best ways to solve this problem without changing the original equipment and instruments. The autonomous inspection r...
