Single PSD (Phase-Sensitive Detector) detection method for target space position and posture

Abstract

The invention relates to the technical field of target space position and posture detection, aims at realizing measurement of a posture angle while a target space position is detected, has a rapid detection response speed, high resolution, simple signal processing circuit and relatively low requirements on a detected environment background and an optical system, and effectively improves the detection efficiency. Therefore, the technical scheme adopted by the invention is a single PSD (Phase-Sensitive Detector) detection method for the target space position and a posture; a plurality of light sources of a detected target light-emitting indication unit emit light according to an appointed time sequence and encoding characteristics; a single PSD is used for detecting to obtain a specific position of each light-emitting light source; corresponding signal processing is combined with an algorithm corresponding to a light source space structured layout to directly analyze a space position coordinate and an angle posture of a detected target. The single PSD detection method is mainly applied to target space detection and posture detection occasions.

Description

technical field [0001] The present invention relates to the technical field of target spatial position and attitude detection, and in particular to a method for simultaneously completing target spatial position and attitude detection using a single PSD, which can be used for aiming and docking systems of aerial unit targets. Specifically, it relates to target spatial position and A single PSD detection method for poses. Background technique [0002] Target space position and attitude detection plays an important role in military, automation and civil fields. However, at present, parameters such as target space position coordinates and attitude angle deflection are obtained mainly through high-speed cameras, photoelectric theodolite and other measuring equipment at home and abroad. Most of them use multiple detectors to measure the spatial parameters of the target. The CCD detector can obtain its spatial position and attitude parameters after collecting and processing the im...
