Problems solved by technology

[0003] There are certain defects in the current technology: when the target is approaching head-on at a speed of more than 100m / s, the pitch angle exceeds 15 degrees, and the target pitch direction moves with variable acceleration. The step-by-step lift on the pitch cannot be accurately controlled by manual prediction. The servo lifts to within the field of view where the next time interval of the target appears

Abstract

The present invention relates to an infrared search and tracking method, device and system based on motion estimation and automatic layer lifting. The method includes the following steps: storing the scene in the space with original image data; processing the original image data, and detecting target information in the image; Associate the same target detected by each weekly scan with the same pipeline, and record the historical information of the target; after receiving the automatic layer lift command, extract the manually selected layer lift target, and scan the automatic layer lift according to the manual selection. Target pipeline information, calculate the historical movement information of the target in the pipeline, predict the next movement position of the target, and calculate the predicted pitch angle of the target; according to the predicted pitch angle of the target, align the center of the detector field of view with the predicted pitch angle. The invention realizes the search technology of the automatic layer-lifting mode under the air-to-air condition by fitting the target motion track and correcting the target preset pitch angle deviation in real time, thereby avoiding the influence brought by artificial estimation errors.

Description

technical field [0001] The invention belongs to an infrared thermal imaging search and track system, in particular to an infrared search and track method, device and system based on motion estimation and automatic layer lift. Background technique [0002] In the current air-to-air infrared search and tracking system, in order to achieve a 360-degree search and alarm for a certain target with a time interval of 1 second, the current method is to artificially estimate the position of the target at the next moment by manually controlling the servo lift. , raise the servo pitch angle to the estimated field of view in advance. [0003] There are certain defects in the current technology: when the target is approaching head-on at a speed of more than 100m / s, the pitch angle exceeds 15 degrees, and the target pitch direction moves with variable acceleration. The step-by-step lift on the pitch cannot be accurately controlled by manual prediction. The servo lifts to within the field...
