Multi-target Tracking Method for Photoelectric Theodolite

Abstract

The photoelectric theodolite multi-target tracking method involves the field of photoelectric measurement and control. It solves the problem that the existing tracking method is only suitable for tracking a single target, and thus cannot effectively use the field of view to measure bursts, simultaneous multi-targets or cluster targets. After stably locking the first captured target at the center of the image, select a new zero point in front of the target's flight direction so that the first captured target deviates from the image center and locks at the new zero point; during the tracking process, enter The angle in the field of view and the position of the target in the image, the position of the zero point is updated in real time, and the main tracking target can also be switched as needed. If the main tracking target disappears, the subsequent extracted target can be switched sequentially to track and lock it at the new zero point. The invention improves the measurement ability of multi-target data, and provides powerful basis for measuring multi-target ballistics, evaluating multi-target damage effects and the like.

Description

technical field [0001] The invention relates to the field of photoelectric measurement and control, in particular to a multi-target tracking method for a photoelectric theodolite. Background technique [0002] The photoelectric theodolite is one of the main optical measurement equipment in the shooting range. It is widely used in the task of measuring the outer trajectory parameters of missiles, rockets and spacecraft, etc., and provides important measurement data for the development, finalization and damage effect evaluation of various aircraft. [0003] The traditional photoelectric theodolite mainly tracks a single target in real time. In the automatic tracking mode, there are usually two stages. The first stage is the target acquisition stage. It usually waits for the target to enter the field of view at a certain waiting point. In the image automatic tracking window, You can see a picture with a reticle and a capture window superimposed in the center of the image. When ...
