The invention discloses an image measurement device and an image measurement method. The device includes: a static image measurement unit, a dynamic image measurement unit, a data processing and control unit, a light source and a workbench. The static image detection unit includes a first optical lens and a static The image sensor; the dynamic image measurement unit includes a second optical lens and a dynamic visual sensor; the light source includes a first light source, a second light source, and the bottom light source of the workbench; 2. The three-dimensional movement of the optical lens; the data processing and control unit is used to receive and process the image data acquired by the static image sensor and the dynamic vision sensor, control the opening and closing of the light source, and control the movement of the workbench. The invention utilizes the advantages of fast response, small amount of data, and fast transmission and processing speed of the dynamic visual sensor driven by brightness change, which can reduce redundant information and improve image measurement efficiency.
Description
technical field [0001] The invention relates to the technical field of workpiece geometry measurement, in particular to an image measurement device and an image measurement method. Background technique [0002] In the manufacturing process, the geometric measurement of parts is an indispensable and important part, and the image measurement method is widely used. Traditional image measurement generally uses static images of area scan cameras, the measured features only occupy a small part of the image, and there is a lot of redundant information in the image. Especially for large target cameras, the high image resolution, slow transmission and processing speed limit the improvement of measurement efficiency. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned defects or deficiencies in the prior art, the present invention provides an image measuring device and an image measuring method. By compiling a measurement program with a static image and measuring with ...
