Abstract

The invention provides a visual tactile automobile high-reflective surface three-dimensional shape measurement method and system, and belongs to the technical field of three-dimensional measurement. Atactile front end used for making contact with a to-be-measured automobile high-reflective surface and a visual rear end used for measuring deformation are built respectively, and a visual tactile automobile high-reflective surface three-dimensional topography measurement system is formed after combination. The opaque coating layer in the touch front end is in contact with a to-be-measured surface and generate deformation, then the projector at the visual rear end projects a coded image to the opaque coating layer to obtain a corresponding projection image, and the point cloud of the to-be-measured high-reflection surface is obtained by calculating the world coordinates of each point on the projection image; and finally, a detection result of the three-dimensional morphology of the to-be-measured high-reflection surface is obtained. The method is comprehensive in measurement, simple in post-processing, high in precision, simple in measurement system installation, low in cost and freeof damage to the measured surface.
