Problems solved by technology

[0005] The technical problem to be solved in the present invention is, aiming at the defects in the prior art, through the fixed connection (i.e. rigid connection, the same below) of the sub-camera on the main camera working in the vibrating environment, the sub-camera outside the experimental environment A relay camera fixedly connected to the cooperation mark is installed at a position between the fixed reference objects that can see both the secondary camera and the fixed reference object to form an attitude camera system; the system to be tested is directly obtained through relay measurement. The position and attitud

Embodiment Construction

[0119] 1. Preparation and installation of attitude camera system;

[0120] 2. Calibrate each camera or camera system, and calibrate the relative position and posture between the main and auxiliary cameras, between the relay camera and the fixed cooperation sign;

[0121] 3. If the experiment needs to calibrate the position and attitude of the main camera affected by the vibration environment through the attitude camera system relay as mentioned above, the attitude camera system will collect the changes without the influence of environmental vibration before the experiment starts. image, solve each rotation matrix, translation vector, etc.;

[0122] 4. In the experiment, each camera of the attitude camera system performs corresponding image acquisition in synchronization with the target image acquisition by the main camera;

[0123] 5. According to the needs of the experiment, as mentioned above, directly obtain the position and attitude of the target to be measured relative t...

Abstract

A relay method of attitute camera system for eliminating influence of vibration environment to flash ranging includes forming attitute camera system by connecting secondary camera to primary camera in vibration environment, connecting relay camera to secondary canera, obtaining position and attitute of measured target to fixed reference object, or obtaining secondary camera position and attitute variation caused vibration for having primary camera variation and revising measured result as per variation.

Description

technical field [0001] The invention relates to the fields of optical measurement image technology, photogrammetry and computer vision, and further refers to a method for relaying the attitude camera system used to eliminate the influence of the vibration environment on the optical measurement. Background technique [0002] Photometric image technology has the characteristics of high precision, non-contact and low cost, and has been widely used in many fields. Photometric image technology measures by processing the image of the target, so what is directly measured is the position, attitude, etc. of the target relative to the camera, and has nothing to do with the absolute movement of the target or the camera. If it is necessary to obtain the absolute quantity of the target position, attitude, etc., the camera is required to be absolutely still or to correct the influence of its movement through additional measures. [0003] For example, a visible light remote sensing satell...
