Embodiment 1

[0037] The embodiment of the present application provides a method for detecting bad pasting of a logo. The method for detecting bad pasting of a logo is applied to an electronic device. The electronic device may be a device capable of detecting bad pasting of a logo, such as a smart phone, a tablet computer, or a wearable device. The operating system of the above-mentioned electronic device may be ios, android, windows system or other operating systems, which are not limited here.

[0038] see figure 1 , the method for detecting bad logo paste mainly includes the following steps 101 to 103:

[0039] Step 101. Obtain a pasted image of the logo through the optoelectronic device, wherein the pasted image of the logo is an image captured by the photoelectric device after pasting the sticker printed with the logo on the product.

[0040] In the embodiment of the present application, the optoelectronic device may be a line laser or a linear laser or the like. It should be noted t...

Embodiment 2

[0047] attached figure 2 It is a method for detecting poor pasting of a logo described in another embodiment of the present application. It should be noted that the attached figure 2In an exemplary method, the optoelectronic device may be a line laser or a linear laser. In the embodiment of this application, the parameters of the line laser or the line laser can be: the laser line scan width (Field Of View, FOV) is 35mm, the pixel accuracy is 0.01mm / pixel, and the installation height is the distance from the lower end surface of the laser head to the product pasted with The surface of the logo sticker is 65mm, the height of the fixing mechanism can be adjusted within ±10mm, the scanning and image processing time is less than 2s, and the steering part of the mechanism can be rationally designed and optimized according to the specific model. Of course, in more embodiments, it is necessary to select different line lasers or linear lasers according to factors such as detection...

Embodiment 3

[0059] attached image 3 It is a method for detecting poor pasting of a logo described in another embodiment of the present application. with attached figure 2 The method of the example is similar, with image 3 The optoelectronic device in can also be a line laser or a linear laser, and its various parameters can also be compared with the attached figure 2 The parameters of the line laser or linear laser in the exemplary method are the same. attached image 3 The exemplary method mainly includes steps 301 to 304, and the details are as follows:

[0060] Step 301 , scanning and pasting the sticker printed with the logo on the product with a line laser, and obtaining a grayscale image of the sticker printed with the logo.

[0061] The terms, concepts, etc. involved in step 301 and the accompanying figure 2 The terms, concepts, etc. involved in step 201 of the example are the same, and the implementation process is also completely the same, and reference may be made to ...

Abstract

A method for detecting bad pasting of a logo, an electronic device, and a computer-readable storage medium, the method for detecting bad pasting of a logo includes: obtaining a pasted image of a logo through a photoelectric device, wherein the pasted image of a logo is a pasted object printed with a logo Paste the image obtained by the photoelectric equipment on the product; calculate or analyze the pasted image of the logo obtained by the photoelectric device; if the result of the calculation or analysis determines that the pasted image of the logo is abnormal, it is determined that the logo pasting is not good. The solution provided by this application can greatly increase the detection rate of bad logo pasting and reduce the missed detection rate of bad logo pasting, and also improve the detection efficiency.

Description

technical field [0001] The present application relates to the field of equipment manufacturing, and in particular to a method for detecting poor pasting of a logo, an electronic device, and a computer-readable storage medium. Background technique [0002] Logo means logo, which is an identification of a certain product. It is usually fixed on the corresponding product in two ways. One is to print directly on the product. For example, the logo of some mobile phones is directly printed on the back of the mobile phone. , the other is to print on other materials (for example, plastic or metal sheet) and then paste it on the product. Among them, the way of pasting the logo on the product often produces problems such as partial warping, unevenness or overall warping. These The problem is collectively referred to as bad logo pasting. [0003] Existing methods for detecting poorly pasted logos basically rely on manual work. Specifically, inspectors detect poorly pasted logos throug...
