A method for cooperative control of a high-speed three-dimensional scanner

Abstract

The application discloses a kind of cooperative control methods of high-speed three-dimensional scanner, belong to three-dimensional scanning control technical field, the application is used to include double black and white industrial camera, double camera acquisition card, DLP light machine, controller and double motion axis high-speed three-dimensional scanner;Control flow is in turn motion axis positioning control, DLP light machine projection and trigger signal sending, double camera synchronous acquisition control, data transmission and three-dimensional reconstruction;Controller integrates motion control, light machine drive, trigger control and four big modules of data transmission, the precise cooperation of each component is realized by unified timing scheduling;The method uses hardware trigger mode, the time synchronization error of double camera acquisition is controlled within 1 μs, the scanning rate of scanner is improved to 120FPS, reaches more than 2 times of traditional structured light scanner, while effectively reducing three-dimensional reconstruction error, improves scanning precision, meets the demand of high-precision, high-speed industrial scanning.
