Problems solved by technology

[0005] However, in the actual use process, it was found that the application has the following problems in product size measurement: 1) The application can only be used for the detection of smaller parts by means of air blowing to the side and automatic positioning of the software. For larger parts Or when the product is inspected, it cannot be positioned or the positioning accuracy is not enough, and it cannot be compatible with multiple products; 2) The application needs to transport the product between cameras on a track and a turntable, and measure the external contour size, height measurement, and internal contour size in sequence For measurement and 3D scanning, there will be positioning errors between each transportation and measurement, which will affect the measurement error. The more steps, the greater the positioning error, and the corresponding measurement error will be larger; 3) Although this application combines 2D measurement with 3D lasers are combined, but the different measurement elements of the product are still measured by the sub-device, the equipment is large; and the measurement direction is fixed, the data is prone to deviation

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a size measuring device integrating a 2D camera and a 3D laser. Background technique [0002] At present, in most product processing operations, it is necessary to inspect the processed products, including inspecting the shape, contour, and size of the products. Currently, the vast majority of product testing is done independently by humans. However, when the size of the product is small, the error of manual measurement is large, it takes a long time, and the efficiency is low, which greatly affects the qualified rate of the product. When the number of products is large, the demand for human resources is large, and the cost of human resources is high. Therefore, it is necessary to carry out automated measurement through measuring equipment to improve efficiency and reduce human resource costs. [0003] However, if the existing measurement device integrates 2D ...
