The high-precision, high-definition color 3D modeling solution composed of a laser 3D scanner, a SLR camera and iReal 3D mapping software, its precision, accuracy and color reproduction are fully in line with applications that require relatively high details, such as damage analysis of the aluminum steering knuckle’s surface. From this three-dimensional color workpiece model, the damaged part of the surface can be clearly seen, providing reliable data support for later repairs.
