Embodiment 1

[0076] Please refer to figure 1 , figure 1 A flow chart of a pointer instrument scale identification method provided in the embodiment of the present application, including:

[0077] Step S110: Obtain the image of the pointer instrument to be recognized.

[0078] In the embodiment of the present application, the processor obtains the image of the pointer instrument to be recognized by the camera device installed in the industrial system through wired transmission or wireless transmission; of course, the processor can also obtain the pointer instrument The recorded video screen, at this time, the pointer instrument image to be recognized is the pointer instrument image at a specific moment in the video screen. The pointer instrument image may include a complete dial and pointer, so as to improve the accuracy of subsequent recognition of the pointer instrument image.

[0079] Step S120: Process the pointer meter image to obtain a pointer image including the pointer of the poi...

Embodiment 2

[0103] Next, on the basis of the first embodiment, how to obtain the scale value pointed by the pointer in the pointer meter image will be described in more detail. see figure 2 , as an implementable manner, step S140: (based on the position of the intersection point on the partial dial, determine the scale value pointed to by the pointer on the pointer instrument), specifically, it may be:

[0104] Step S141: Divide the scale range of the partial dial into N parts, where N is an integer greater than 1, and each part represents a numerical value.

[0105] In order to better explain the idea provided by the present application, a part of the dial is an example for the whole of the dial. In the embodiment of the present application, the scale range can be divided into N parts according to the scale specification of the dial, but the division method is not limited, it only needs to be able to represent a scale value for each divided part. For example: if the dial is a fan-shap...

Embodiment 3

[0129] Optionally, see image 3 , image 3 The electronic device provided in the embodiment of the present application is a schematic structural diagram, and the electronic device may include: at least one processor 210 , such as a CPU, at least one communication interface 220 , at least one memory 230 and at least one communication bus 240 . Wherein, the communication bus 240 is used to realize the direct connection and communication between the processor and the camera device or between the equipment and the camera device. Wherein, the communication interface 220 of the device in the embodiment of the present application is used for signaling or data communication with other node devices (such as a device and a camera). The memory 230 may be a high-speed RAM memory, or a non-volatile memory (non-volatile memory), such as at least one disk memory. Optionally, the memory 230 may also be at least one storage device located far away from the aforementioned processor. Computer...

Abstract

The embodiment of the invention provides a pointer type instrument identification method and electronic equipment, and relates to the field of image processing. A processor processes a pointer type instrument image to obtain an intersection point of a pointer and a dial in the pointer type instrument image, and the reading of a pointer type instrument is determined through the position of the intersection point on the dial; compared with a manual reading mode in the prior art, the manual cost is reduced, and the reading efficiency of the pointer instrument is improved. Compared with the priorart that a large number of sample images of the pointer type instrument are needed when the pointer type instrument image is read through the neural network, the method can achieve the obtaining of the scale value pointed by the pointer in the pointer type instrument image without a large number of samples, and improves the recognition efficiency.

Description

technical field [0001] The present application relates to the field of image processing, and in particular, relates to a pointer instrument scale recognition method and electronic equipment. Background technique [0002] With the development of science and technology, more and more industries are developing in the direction of automation. In the industrial system, in the process of upgrading some automation equipment that has been in operation for a long time, it is necessary to upgrade the pointer instruments installed on the automation equipment. The scale is read, and the readings are uploaded to the industrial system to realize the upgrade of automation equipment. At present, the scale reading of the pointer instrument on the automation equipment is mainly based on the staff reading the collected pointer instrument image or inputting the collected pointer instrument image into the pre-trained neural network model for reading. However, reading the pointer meter or the im...
