Application of non-contact laser image contour size measurement system

The measuring instrument adopts a cantilever three-axis motion structure, and the internal main frame is made of granite marble, which can ensure a stable mechanical structure. The tested workpiece can be placed on a glass worktable, and through effective 3D motion control, a combined working mode of 3D laser displacement sensor and imaging module (camera+lens+light source) can be used to measure the plane and height dimensions of the target product.

By using a 3D laser displacement sensor to quickly and densely scan the surface of the target product, three-dimensional point cloud coordinate information is collected and generated. The product's 3D graphics are then processed by measurement software, and the point coordinates of the target position in the 3D graphics are extracted through software algorithms, including but not limited to high points, low points, and average points. Finally, based on the coordinate information of all extracted target positions, the software can further analyze and calculate the specific results of the final target size, including but not limited to flatness, coplanarity, curvature, height, depth, and pitch.

Establish a planar measurement reference coordinate system on the target product through the imaging module (camera+lens+light source), and then extract and evaluate the key planar dimensions of the product, including but not limited to: point coordinates, distance, height difference, angle, diameter, perimeter, area, positional accuracy, parallelism, symmetry, concentricity, and coaxiality.
