A non-contact type attitude measurement system for three axis simulator

摘要

The present invention is non-contact 3-axis simulator for the precise measurement of the position of the 3-axis attitude control rocket simulator relates to a position measuring system. The present invention includes the coordinate plate are laser pointer is displayed; Camera to measure the image of the laser pointer indicated above; And wherein in use the image information obtained by the camera position and attitude of the object of the conventional non-contact type comprising a computer for calculating the position measuring system, the object is in the air unit and the air form the ball bearing, the rotation axis on the air bearing ball connected to the simulator, and the pitch axis consists of three laser pointers are fixed rest simulators installed, John shaft, and air bearing system that is rotated in the roll axis, three-axis, the coordinate axis of rotation and the outer plate is the air bearing ball in the air bearing system match to be installed in the same direction and the color is painted in two different colors so as to facilitate the measurement coordinates when obtaining image information by the camera, the camera is mounted outside the air bearing system forming the three laser pointer on the coordinate plate measuring the image of a triangle, and wherein the computer is a pitch angle of the simulator in the obtained image is measured by the camera, yaw angle, but calculating the roll angle, pitch angle and the coordinates of the triangle formula , yaw angle and the coordinates of the triangle equation , the roll angle and the coordinates of the triangle equation The present invention is moved on the coordinate plate in the same motion as a laser pointer are also air bearing system with the air bearing system air bearing system is moved by the air cushion. The camera transmits the images to a computer to detect, process the image to be stored inside the computer calculates the current position and attitude of the simulator.
