Problems solved by technology

Because of the regularity of the Hough transform, the amount of calculation increases exponentially with the growth of the parameter space. It is difficult to meet the real-time detection requirements for ellipses, and because of the different viewing angles of circular instruments, it is impossible to rely solely on the detection of circles. Meet the requirements

Abstract

The present ivnention relates to a circular / elliptic / sequence meter monitoring method based on conout profile of body in transformer substation, belonging to the field of transformer substation meter monitoring technology. It is characterized by that its total control terminal computer has a remoter meter detection / fetch module capable of implementing circular / elliptic / square search and detection algorithm based on contour profile of body, and said monitoring method includes the following steps: utilizing wireless local area network to control patrol inspection robot in the transformer substation, according to predefined patrol inspection line searching the space position of the meter locked by subprogram in preset search space range, then using visible light camera head to obtain the geometrical image of the motor, then transferring said image into total control terminal, makin data processing so as to attain the goal of implementing remote monitoring and control.

Description

technical field [0001] The invention belongs to the technical field of substation instrument monitoring based on computer image processing. Background technique [0002] Divided according to the application angle, the present invention mainly solves the reading problem of remote instruments. Patents related to solving this problem already exist, but the method is mainly by setting a special electrical / optical circuit on the instrument or directly reading it manually, and then transmitting it to the remote end through an electrical / optical cable or wireless communication. for example: [0003] In 1993, the "remote meter reading device" of GPT Co., Ltd. (England) with the publication number of 1073008 was connected to the interface of the meter to be tested by a pair of optical fibers, and the reflected light path reached the sensor and then passed to the far end, similar to this There is also the "RF Transponder of the Meter Automatic Reading System" (RF REPEATER FORAUTOMAT...
