Embodiment 1

[0079] figure 1 It is a flow chart of a flatness detection method provided in Embodiment 1 of the present invention. The flatness detection method provided in the embodiment can be executed by a flatness detection device, which can be realized by software and / or hardware, and the flatness detection device can be composed of two or more physical entities, or Can be a physical entity. For example, the flatness detection equipment can be a mobile phone, an industrial control computer, etc. In the embodiment, an industrial control computer is used as an example to describe the flatness detection device.

[0080] Optionally, the flatness detection device can be used as an independent device to directly acquire externally input image data for processing. Alternatively, the flatness detection device can also be integrated in the flatness detection system. At this time, the flatness detection device can obtain and process data obtained by other data acquisition devices in the flatn...

Embodiment 2

[0099] figure 2 It is a flow chart of a flatness detection method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments.

[0100] In this embodiment, the target object is a keyboard keycap, the detection surface is a plane on which characters are printed on the keycap, and the target object is a character.

[0101] Specifically, the target object is a keyboard keycap, which may be a specific keycap, several specific keycaps or all keycaps in the keyboard. In the embodiment, it is described that the target objects are all keycaps in the keyboard as an example. Further, the detection surface is a plane on which characters are printed in the keycap, that is, a user touch surface. Wherein, characters such as letters, numbers and / or symbols are printed on the detection surface of each key cap, and in the embodiment, the characters printed on the key cap are used as the target object of the key cap.

Abstract

The embodiment of the present invention discloses a flatness detection method, device, equipment, storage medium and system, relating to the field of equipment detection, which includes: acquiring an image containing the detection surface of a target object; extracting the skeleton line of the target object in the image, the target object Located in the detection surface of the target object; calculate the error value between the skeleton line and the standard skeleton line, the standard skeleton line is the skeleton line of the standard object, and the standard object is located in the detection surface of the standard object; determine the flatness detection result of the detection surface according to the error value . The above-mentioned method can solve the technical problems of slow flatness detection speed, low precision and high cost in the prior art.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of equipment detection, and in particular to a flatness detection method, device, equipment, storage medium and system. Background technique [0002] With the development of intelligent technology, the types of electronic products that people come into contact with in daily life and the types of automation equipment used in factories are becoming more and more abundant. However, keys for inputting commands are usually arranged in various devices. When there are many keys, the keys are integrated in the key area for the convenience of user operation. For example, the keyboard of a computer can be considered as a typical key area. [0003] Generally speaking, before the equipment leaves the factory, rigorous testing is required. At this time, for the keys, the flatness of the keycaps needs to be tested. Among them, the keycap is the part that the user mainly contacts. If the keyca...
