A dimension measurement system and measurement method based on lab VIEW development platform

Abstract

The invention provides a dimension measurement system based on a Lab View development platform, and a measurement method thereof. The dimension measurement system based on a Lab View development platform includes a upper computer, a PLC, a 3D laser camera and a linear module device, wherein the upper computer is used to send an operation instruction to the PLC, and complete signal interaction withthe 3D laser camera and the linear module device through the PLC; the PLC is connected with the upper computer, and receives the instruction of the upper computer to control triggering of the 3D laser camera and movement of the linear module device; the 3D laser camera is arranged on the linear module device; the 3D laser camera is used to scan the measured object to generate 3D point cloud dataand gray scale data, and transmit the data to the upper computer; and the linear module device is connected to the PLC, and is controlled by the PLC to drive the 3D laser camera to move. The dimensionmeasurement system based on a Lab View development platform has the advantages of simple structure, high noise resistance, wide visual field, convenient installation, high accuracy, and high universality, and solves the problems of poor stability, limited visual field, complicated configuration, poor noise resistance and difficult integration caused by a traditional measurement system.

Description

technical field [0001] The invention relates to a size measurement system, in particular to a size measurement system based on a Lab VIEW development platform and a measurement method thereof. Background technique [0002] Today's production industry has extremely strict requirements on size. For the measured objects such as injection-molded shells and welded circuit boards, the height of the measured objects such as column heads, pin headers, and electronic components is the basis for judging whether the product meets the production requirements. an important indicator. [0003] Traditional dimension measurement systems use industrial cameras to capture plane images, and calculate the height of the measured target on the measured object by analyzing grayscale or color images. Such systems usually have strict requirements on the working environment, poor noise immunity, and small field of view , The configuration is cumbersome, the accuracy is limited, and the insensitivity...
