Product inspection method and device, producing system and computer storage medium

A product inspection device, comprising:

• one or more processors;
• and
• a memory for storing one or more programs, wherein when the one or more programs are executed by the one or more processors, the one or more processors implement the following operations;
• conducting image acquisition on a product assembly line to obtain a production line image;
• extracting a product image including a product to be inspected from the production line image;
• extracting an inspection point image in a part inspection area in the product image;
• inputting the inspection point image into an inspection model to obtain an inspection result;
• and
• determining that the product to be inspected in the product image has defects under the condition that the inspection result meets any of the following conditions:
• the inspection type of the inspection point image in the inspection result is a defect type;
• the edge box position of the inspection point image in the inspection result exceeds the first edge box position range or the edge box position of the inspection point image does not exist;
• and
• the feature similarity between the inspection point image in the inspection result and a reference part image is smaller than a similarity threshold.

A producing system, comprising a product assembly line, a camera arranged towards the product assembly line, and an industrial personal computer, wherein the industrial personal computer is used for implementing the following operations:

• conducting image acquisition on a product assembly line to obtain a production line image;
• extracting a product image including a product to be inspected from the production line image;
• extracting an inspection point image in a part inspection area in the product image;
• inputting the inspection point image into an inspection model to obtain an inspection result;
• and
• determining that the product to be inspected in the product image has defects under the condition that the inspection result meets any of the following conditions:
• the inspection type of the inspection point image in the inspection result is a defect type;
• the edge box position of the inspection point image in the inspection result exceeds the first edge box position range or the edge box position of the inspection point image does not exist;
• and
• the feature similarity between the inspection point image in the inspection result and a reference part image is smaller than a similarity threshold.
