Problems solved by technology

The traditional method of checking the brand and model information of projectors is to rely on the eyes of workers on the assembly line for identification. The identification efficiency is low, the labor cost of identification is high, and workers are prone to visual fatigue after working for a long time, resulting in a decline in identification accuracy.

Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0065] Please refer to figure 1 , the present invention provides a method for identifying the brand and model of a projector, comprising the following steps:

[0066] Step S1: collect the image of the area where the projector brand and model are located;

[0067] Step S2: Preprocessing the collected image, extracting the candidate target area;

[0068] Step S3: using the target area screening strategy to screen the candidate target area to obtain the target area;

[0069] Step S4:: According to the obtained target area, use OCR technology to identify the characters in the target area to obtain the character string in the target area

[0070] Step S5: Match the identified character string in the target area with the character string data in the brand and model database to obtain the matching result of the brand and model.

[0071] In an embodiment of t...

Abstract

The present invention relates to a method for identifying the brand and model of a projector, comprising: step S1: collecting images of the area where the brand and model of the projector are located; step S2: preprocessing the collected image, and extracting a candidate target area; step S3 : adopt the target area screening strategy to screen the candidate target area to obtain the target area; step S4: according to the obtained target area, adopt OCR technology to identify the characters in the target area to obtain the character string of the target area; step S5: identify Match the target area character string with the character string data in the brand and model database to get the matching result of the brand and model. The invention can accurately and automatically identify the brand and model text information on the shell surface of the projector body.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method for recognizing the brand and model of a projector. Background technique [0002] During the industrial production process of projectors, the processed projectors need to be boxed. The general process of packing is: check whether there is any defect in the appearance of the projector → paste the factory label → check whether the brand and model information of the projector is correct → put the projector into a plastic bag → install the protective lining → put it in the packing box. The traditional method of checking projector brand and model information is to rely on the eyes of workers on the assembly line for identification. The identification efficiency is low, the labor cost of identification is high, and workers are prone to visual fatigue after working for a long time, resulting in a decline in identification accuracy.
