Single-camera positioning method for moving objects in space

Abstract

The invention discloses a single-camera positioning method for a space moving target, and the technical problem to be solved is to use a single-camera to perform high-precision positioning of the space moving target. The technical solution is to use a single camera to track and shoot the movement of the measured target, measure the coordinates of the optical center of the camera at each moment and the space angle formed by the connection between the optical center and the target, and combine the movement characteristics of the target, according to a series of shooting moments. For the space and time relationship of the target, the method of curve fitting, translation intersection and collinear equation is used to finally obtain the spatial position of the space moving target at each moment, so as to achieve the purpose of positioning. The invention realizes the positioning of the space moving target by adopting the imaging measuring means based on the single camera, and the precision is better.

Description

Single-camera positioning method for space moving targets Technical field The present invention relates to technical fields such as camera measurement, target positioning, especially refer to utilizing single-image camera to space moving object The method of marking the positioning. Background technique The camera measurement principle is to measure the positional information of the target by processing the target image taken by the camera, The spatial positioning of the target has the characteristics of high precision, non-contact, and low cost. It has been used in the fields of target positioning and target tracking. There are more mature applications. In target positioning and target tracking, fixed measurement base stations are generally built in different regions, and electric Theodolite, high-speed camera and other photometric equipment track and shoot the target, acquire images and data, and then use two or more stations The traditional photogrammetry methods...
