Description

Technical Field

[0002] With the continuous progress of society and the rapid development of science and technology, the requirements for product specifications are becoming higher and higher. In order to ensure that the products can meet the predetermined requirements, it is necessary to detect the two-dimensional and three-dimensional dimensions of the products.

[0003] Traditional manual inspection methods often use vernier calipers, height gauges, plug gauges, etc. to measure the various dimensions of the product, and then read the values ​​manually. This inspection method is inconvenient to operate, takes a lot of time, has high labor intensity, and occupies a lot of manpower and material resources. In addition, long-term work can easily fatigue the human eye, and it is easy to cause false detection and missed detection. The inspection accuracy is low, so the overall quality and yield of the product are low, which is not conducive to production control and cannot meet production needs.

[0004] In the process of automated assembly line production, in order to ensure that the size of a certain part of the product is qualified, it is often necessary to perform dimensional inspection on specific parts of the product to eliminate products with unqualified sizes. In factory applications, high-precision dimensional measurement is generally performed by technicians operating measuring equipment. The dimensional measurement is based on the drawing to detect whether the product size is within the tolerance range to find errors in shape and size. The actual size of the product is often indispensable, but it may not be obtained due to complex object surfaces or objective physical conditions. Machine vision inspection technology can deal with such problems well.
