[0002] In modern automobile manufacturing, each component of the car needs to be matched with high precision to ensure the performance, safety and reliability of the car. For example, the precision of engine components directly affects the power output and fuel efficiency of the engine; the precision of the car body is related to the appearance quality, wind resistance coefficient and sealing of the car. As consumers' requirements for automobile quality continue to increase, automobile manufacturers must use more advanced precision inspection equipment to ensure product quality.

[0003] Simple measuring tools such as calipers and micrometers are used to measure linear dimensions. These tools are relatively simple to operate, but the measurement accuracy is limited, and it is difficult to measure parts with complex shapes. Samples and plug gauges are used to compare specific dimensions. This method can only perform qualitative or rough quantitative measurements, and it is difficult to obtain accurate three-dimensional dimension information. In the early stages of the development of the automotive industry, the requirements for accuracy were relatively low, and traditional measurement methods could basically meet production needs. With the continuous advancement of automotive technology, the requirements for accuracy have gradually increased, and the shortcomings of traditional methods have gradually become apparent.
