Embodiment 1

[0069] Such as figure 1 As shown, it is a flow chart of the battery cover quality detection method provided by the embodiment of the present invention. The battery cover quality detection method may include the following steps:

[0070] Step S101: Obtain the battery cover image of the battery cover to be detected.

[0071] In practical applications, the camera can be fixedly installed at a set height, and a scale with a known length can be set. It should be noted that, in order to locate the scale from the captured image, the scale is usually set to be the same as the object to be collected. Different and unique, and placed at a fixed position within the camera's field of view, the battery cover image of the battery cover to be inspected that is transported by the conveyor belt can be obtained after installation is ready. For scenarios where the installation position of the camera is fixed, the camera can also be installed according to the set height, and the ratio of the act...

Embodiment 2

[0079] Such as figure 2 As shown, it is another flow chart of the battery cover quality detection method provided by the embodiment of the present invention. The battery cover quality detection method may include the following steps:

[0080] Step S201: Obtain the battery cover image of the battery cover to be tested; the battery cover image includes the front image of the battery cover to be tested, see image 3 , is a schematic front view of the battery cover to be tested provided by the embodiment of the present invention.

[0081] Step S202: extracting the outline of the battery cover to be detected from the battery cover image.

[0082] Step S203: Determine the actual size of the battery cover to be detected based on the outline of the battery cover to be detected extracted from the front image.

[0083] In an implementation manner, the actual size of the battery cover to be detected can be determined in the following manner: obtain the number of pixels corresponding t...

Embodiment 3

[0088] Such as Figure 4 As shown, it is another flow chart of the battery cover quality detection method provided by the embodiment of the present invention. The battery cover quality detection method may include the following steps:

[0089] Step S301: Obtain the battery cover image of the battery cover to be tested; the battery cover image includes the side image of the battery cover to be tested, see Figure 5 , is a schematic side view of the battery cover to be tested provided by the embodiment of the present invention.

[0090] Step S302: extracting the outline of the battery cover to be detected from the battery cover image.

[0091] Step S303: extracting the deformation detection area from the side image.

[0092] Step S304: Perform edge curve fitting based on the edge of the deformation detection area to obtain a fitting curve of the deformation detection area.

[0093] In an implementation manner, the least square method may be used for edge curve fitting. Of co...

Abstract

The invention discloses a battery cover quality detection method and device, computer equipment and a storage medium, and relates to the technical field of image processing and product quality detection. The battery cover quality detection method comprises the steps; acquiring a battery cover image of a to-be-detected battery cover; extracting the contour of the to-be-detected battery cover from the battery cover image; performing quality anomaly detection on the to-be-detected battery cover based on the contour of the to-be-detected battery cover, the quality abnormity comprising at least one of size abnormity, deformation and buckling abnormity. According to the scheme, the problem of abnormal product installation caused by unqualified battery covers is solved, qualified products and unqualified products of the battery covers can be automatically and accurately distinguished, then the unqualified products are removed, manual detection can be replaced, and the production efficiency is effectively improved; in addition, whether the battery cover has quality problems or not is judged in an image processing mode, unqualified products are removed, manual judgment is not needed, and manpower and time cost are saved.

Description

technical field [0001] The invention relates to the technical field of image processing and product quality inspection, in particular to a battery cover quality inspection method, device, computer equipment and storage medium. Background technique [0002] In the production process of the battery cover, due to certain reasons such as processing technology, problems such as deformation, abnormal size such as being too long or too short, and missing buckles may occur; moreover, if the quality inspection of the battery cover is not carried out It is easy to rework and return materials after installation, and there may be quality problems when the product leaves the factory, and the user experience is poor. Therefore, it is necessary to perform quality inspection on the battery cover before installation, and reject unqualified products in advance to ensure product quality. Line site material quality. [0003] In the prior art, a manual method is used to judge whether the batter...
