Three-dimensional attitude and position measuring device based on infrared visual guidance and laser ranging

Abstract

The invention discloses a three-dimensional attitude and position measuring device based on infrared visual guidance and laser ranging. The three-dimensional attitude and position measuring device is mainly composed of a laser Y-axis rotating component A, a laser X-axis rotating component B, a laser component C, an image acquisition component D, a target I and a target object II. A measuring point of the laser component (C) is located on the target (I) of the target object (II) by adjusting the laser X-axis rotating component (B) and the laser Y-axis rotating component (A), image acquisition is conducted on the target (I) through the image acquisition component (D), the position of the laser measuring point is continuously optimized through image processing, finally, the laser measuring point is located in the center of the target (I), and the position of the target (I) is accurately positioned. In a small area near the central point of the target (I), a series of distance data are obtained through scanning of the laser component (C), and the spatial position and attitude of the target (I) are obtained through calculation by adopting a spatial plane fitting method based on the distance data and the inclination angle of a sensor, so that position measurement and attitude measurement of a spatial target object are accurately, quickly, stably and continuously realized.

Description

Problems solved by technology

The traditional measurement method has the shortcomings of narrow measurement range, inability to measure on-site and high requirements for the environment, which can no longer meet the requirements of modern measurement.

At present, the relevant products developed in China basically have the disadvantages of low measurement efficiency, low measurement accuracy, poor stability, and inconvenient use, while foreign products are generally very expensive and the use method is relatively complicated.
