Abstract

The present application discloses a visual measurement system. The visual measurement system comprises: an image acquisition device, wherein the image acquisition device has an acquisition port located in a reference plane, and the acquisition port is configured to obtain image data of a to-be-tested object. The visual measurement system further comprises: a distance measuring device, wherein thedistance measuring device comprises at least two range finders, the measuring end of each range finder is located in the reference plane, each range finder is configured to obtain distance data from the measuring end to the measuring direction of the to-be-tested object, and there is a preset angle between the measuring direction and the reference plane; and a processing device, wherein the processing device is respectively electrically connected with the image acquisition device and the distance measuring device, and is configured to obtain coordinate parameters of the test point in a test plane according to the image data of the to-be-tested object, and obtain distance parameters between the test point and the reference plane according to the distance data provided by the distance measuring device.

Description

technical field [0001] The invention relates to the technical field of measurement, and more particularly to a visual measurement system. Background technique [0002] Non-contact rangefinder cameras and rangefinders are based on photoelectric, electromagnetic, ultrasonic and other technologies. When the measuring element of the instrument is not in contact with the surface of the measured object, it can obtain various appearance size data characteristics of the measured object. . Compared with traditional contact ranging systems, non-contact ranging cameras and rangefinders have higher precision, more convenient operation, and higher safety factor, so they are used in many fields of industrial production and scientific research. [0003] The modern production process requires higher and higher processing efficiency. Non-contact automatic detection can not only greatly improve the detection efficiency, but also avoid damage to the object to be tested by the detection system...
