Wireless positioning location detection system based on laser and ultrasonic fusion scanning

Abstract

The invention discloses a wireless location smoothness detection system based on laser and ultrasonic fusion scanning. The system is characterized in that the system achieves accurate measurement on the smoothness of a large plane workpiece, based on an ultrasonic and laser scanning fusion technology, and combined with a multipoint wireless radio-frequency location method, wherein the ultrasonic and laser scanning fusion technology is divided into two links; one link is that height data within a transmission path range required by laser scanning is obtained by using an ultrasonic scanning method, and the height data serves as a preset reference height for a laser target; and the other link is that a laser scanner is installed at a known height, the height of the laser target is preset, the laser is emitted, and the height data of a position where the mark target is located is calculated. The multipoint wireless radio-frequency location method comprises the steps that radio-frequency monitors are installed at three known coordinate points selected from the surface of the workpiece; accurate coordinates of a position of the target are determined by a three-point location method; and a plane pattern of the measured workpiece is obtained finally by combining with the height data of the position of the target.
