Abstract

The invention discloses a three-dimensional surface shape measurement device and method for a mirror object based on infrared stripes. The device comprises a computer, an infrared projector, a CCD infrared camera, a to-be-measured mirror object, frosted glass, a reflecting mirror with a circular mark on the surface, a first high-precision horizontal moving guide rail, a fixed plate and a second high-precision horizontal moving guide rail. The method comprises the following specific steps: preliminarily constructing a measurement device: 1) preliminarily constructing the measurement device; 2)calibrating the measurement device; 3) completing construction of the measurement device; 4) collecting stripe information of two positions; 5) solving three-dimensional shape depth information of themirror object, so as to complete three-dimensional shape measurement of the mirror object.

Description

technical field [0001] The invention relates to the field of three-dimensional surface shape measurement of mirror surfaces and highly reflective objects, in particular to a device and method for three-dimensional surface shape measurement of mirror objects based on infrared stripes. Background technique [0002] With the advent of the information age, the three-dimensional shape information of objects plays an increasingly important role in various industries. Especially in precision manufacturing, automobile industry, aerospace and other fields, the rapid and accurate acquisition of three-dimensional shape information of objects has increasingly become a hot and difficult point of people's attention and research. In recent years, Optical Three-Dimensional Measurement Techniques (Optical Three-Dimensional Measurement Techniques) has been widely used in industrial inspection, manufacturing, medical industry, aerospace and other fields due to its non-contact, high precision, ...
