Problems solved by technology

In the process of training the model, all the data in this method are original data. On the one hand, the collection workload is large, and secondly, the generalization ability of the model is not strong; The initial position and split direction need to be consistent, which limits its practical use

Embodiment Construction

[0028] The object of the present invention is to provide a method and device for intelligent recognition of pointer instrument values ​​with strong operability, high recognition accuracy, fast speed and high robustness.

[0029] A major feature of the recognition device is that it has the function of self-adapting to the shooting angle, which can be self-corrected through the prefabricated cross positioning mark without manual adjustment. The set is attached figure 1 As shown, it is composed of a bracket (1), a program-controlled cloud platform (2), a video camera (3), a cross mark (5) and a computer. First place the bracket (1) in front of the dial (4) to be identified, then fix the program-controlled pan-tilt (2) fixedly connected to the camera (3) on the bracket (1), and there are two left and right cross marks on the dashboard Make a mark, and then the camera takes an image to detect the position of the two cross marks, and judges the degree of deviation between the top, ...

Abstract

The present invention belongs to the field of machine vision, and relates to an intelligent identification method and apparatus for a numerical value of a pointer instrument. The present invention provides an identification method and apparatus, wherein a model is trained to intelligently identify a numerical value of a pointer instrument based on an anti-sample model training method by using a convolution neural network model, and a camera shooting angle adaptive adjustment technology is provided. The apparatus has a shooting angle adaptive function and can self-correct a shooting angle, without the need for performing precision adjustment on the apparatus before use. In the method, an anti-sample training convolution neural network identification model is adopted, so that the workload for original data acquisition is greatly reduced; and numerical values of various instruments can be identified at the same time, so that there is no need using multiple cameras to shoot separately, so that cost is saved. The method and apparatus provided by the present invention have the characteristics of high robustness, high accuracy, fast identification, strong operability and convenient transplantation and the like.

Description

technical field [0001] The invention belongs to the field of machine vision, and relates to a method and device for intelligently recognizing the value of a pointer instrument, in particular to a recognition method and device capable of self-correction by using adversarial samples to train a convolutional neural network recognition model. Background technique [0002] Due to its stability, reliability, easy maintenance, and ability to reflect the changing trend of the measured instrument, the pointer instrument is widely used in chemical industry, electric power, automobile and other industries. However, the identification of pointer instruments is mostly done by human eyes, which is not only time-consuming and laborious but also inefficient, and its readings are greatly affected by subjective factors. Therefore, it is necessary to develop a set of automatic identification devices for pointer instruments. [0003] At present, the recognition of pointer instruments mostly ado...
