[0002] Line scanning image measuring instrument is a measuring device based on digital imaging technology. It captures the two-dimensional image of the object through a line scanning camera and uses a computer to process and analyze the image, thereby achieving accurate measurement of the object's size, shape, position and other parameters. Line scanning image measuring instrument plays an important role in various industries due to its advantages of high precision, high efficiency and non-contact measurement. It can also provide a variety of measurement functions and data processing methods to meet the measurement needs of different industries.

[0003] However, in the actual application of the existing line scanning image measuring instrument, if the measured plate has warping deformation, in order to avoid the error of the test result, the conventional method is to flatten the measured plate with a glass plate, but the glass plate needs to be moved manually, which not only leads to low measurement efficiency, but also the glass plate is very easy to have relative displacement with the measured plate, which eventually causes damage to the measured plate. For this reason, a line scanning image measuring instrument is proposed. Utility Model Content
