Optoelectronic system-based continuous-tracking automatic-switching method

Abstract

The invention discloses an optoelectronic system-based continuous-tracking automatic-switching method. The optoelectronic system-based continuous-tracking automatic-switching method comprises the following steps of carrying out capture and tracking of a missile target in a take-off initial-segment by a large-view field television channel, carrying out parallel acquisition of target deviation values output by large and small view field television video trackers according to a sampling period, setting a square position port door by the deviation valve as the center output by the large view field television video tracker, monitoring if the deviation values output by the small view field television video tracker are continuously fall into the square position port door repeatedly, transmitting the deviation values output by the small view field television video trackers into a servo-system when it is determined that the target extracted by a small view field television is the same as a missile target extracted by a large view field television, and carrying out target tracking so that it is realized that when a missile target flying from the near to the distant is automatically tracked and measured by the optoelectronic system, large view field television and small view field television tracking channels are switched automatically. The optoelectronic system-based continuous-tracking automatic-switching method avoids influences produced by manual operation-caused uncertain factors thereby improving reliability and accuracy of switching from the large view field television tracking channel to the small view field television tracking channel.

Description

technical field [0001] The invention belongs to the field of optoelectronics, and mainly relates to an optoelectronic system for measuring the initial trajectory of a flying missile, in particular to an automatic switching method for continuous tracking measurement of the optoelectronic system. Background technique [0002] In order to realize autonomous detection, tracking, and ballistic measurement of targets such as missiles moving from near to far at high speed, optoelectronic systems generally adopt multi-field of view and multi-sensor solutions. This optoelectronic system includes optoelectronic pointing device, video tracker, servo system, control computer and console. The photoelectric pointer is a platform with two axes and two frames, and the large field of view TV, small field of view TV, and laser rangefinder are all installed on the same frame. Large field of view TV and small field of view TV provide image information of the target visible band. Large field of...

AI Technical Summary

Problems solved by technology

However, it takes a certain amount of time for the operator to react from seeing the characteristics of the target to operating the switching button correctly, and it is difficult to grasp the exact timing of switching

In addition, the psychological quality and operation level of each operator are different, which is prone to human error

In other words, manual operation has relatively high requirements for operators, and a little carelessness will lead to tracking failure, especially for complex background conditions such as mountains and seas, manual operation is more difficult
