Target real-time tracking control method and system

Abstract

The invention discloses a target real-time tracking control method and system. The method comprises the steps of calculating a short-wave infrared field of view A and an area array single-photon imaging field of view B, extracting pixel coordinates of a suspicious target in the field of view A, judging whether the suspicious target is in the field of view B or not, if not, rotating a rotary table to enable the suspicious target to fall in the field of view B, and identifying whether the suspicious target is a target to be tracked or not through single-photon three-dimensional imaging. And performing three-dimensional imaging on the to-be-tracked target according to the time interval, and fitting a three-dimensional trajectory equation to follow and aim the to-be-tracked target in real time. The system comprises a view field calculation module, a passive short-wave infrared imaging module, an active area array single-photon imaging module, a pixel coordinate extraction and judgment module, a target identification module, a real-time tracking module and a two-dimensional turntable. According to the method and the device, rough positioning and reliable extraction of the suspicious target can be rapidly realized, and the motion track can be predicted in real time by using historical data of the target, so that a reference is provided for capturing the target again after the target is lost.

Description

technical field [0001] The invention belongs to the technical field of target control, in particular to a target real-time tracking control method, and also to a target real-time tracking control system. Background technique [0002] When a moving target moves rapidly, its background may be clouds and nature, and the environment in which it moves may be a low-light environment or an environment without natural light illumination, and sometimes there may be smoke and fog between the target and the detector. In other cases, in order to track and detect such moving targets, the area array single photon is often used to have certain physical properties of penetrating smoke, and active area array single photon imaging is used to actively detect the target. [0003] However, due to the small number of single-photon pixels in the area array, generally only 32 × 32 or 64 × 64 arrays, the detection field of view of the target is generally small, only a few tenths to a few milliradian...

Problems solved by technology

[0003] However, due to the small number of single-photon pixels in the area array, generally only 32×32 or 64×64 arrays, the detection field of view of the target is generally small, only a few tenths to a few milliradians, and it is difficult to search and find the target

In addition, when tracking the target, if the target moves too fast, the target may move out of the field of view, and the target cannot be tracked and imaged. Therefore, it is necessary to solve the problem of predicting the next or multiple positions in the target movement
