Abstract
The invention discloses a spiral scanning method for rapid omnibearing search, which is applied to the safety protection of infrared periscopic scanning, protection of key parts and the like, realizes rapid omnibearing search of long-wave infrared and has high scanning efficiency. The method disclosed by the invention has the positive effects that: a scanning mechanism is preposed at the initial position of a corresponding working mode before the scanning motion, and one cycle of scanning search motion is finished on the azimuth direction and pitching direction according to the set scanning speed and motion trail respectively, thereby reducing the pre-scanning time on the pitching direction and improving the scanning efficiency. The method disclosed by the invention realizes rapid omnibearing search of a long-wave infrared optical system at low-altitude and high-altitude modes.
Description
Technical field
The invention belongs to scanning technique field, be specifically related to a kind of spiral scan method for quick all direction searching.
Background technology
In infrared acquisition field, the scan mode that research realizes quick all direction searching to infrared target has great importance and is worth.The scan mode that infrared target is carried out to all direction searching normally scanning mechanism by constantly changing the sweep limit in pitch orientation, complete the continuous panorama scanning on azimuth direction, its movement locus as shown in Figure 1, this scan mode need to be accelerated and moderating process in the time of each circular scan, greatly increase the prescan time that scanning mechanism produces in the time changing the sweep limit of pitch orientation, and then affected the scan efficiency of system.How to reduce the prescan time of scanning mechanism, improve scan efficiency, the requirement that meets military mission is crucial.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of spiral scan method for quick all direction searching, be applicable to the aspect such as security protection, the protection of keypoint part of infrared panoramic scanning, realize the quick all direction searching of LONG WAVE INFRARED, had advantages of that scan efficiency is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of spiral scan method for quick all direction searching, comprises the steps:
The velocity amplitude that the first step, setting scanning mechanism should reach on azimuth direction;
Second step, determine the sweep limit of scanning mechanism in pitch orientation;
The 3rd step, scanning mechanism is placed in to the initial position of corresponding mode of operation, and scanning mechanism is adjusted in pitch orientation to the extreme lower position of corresponding mode of operation;
The 4th step, within a search cycle, make the sweep velocity of scanning mechanism on azimuth direction accelerate to the velocity amplitude setting, make scanning mechanism in the sweep limit of pitch orientation, do at the uniform velocity lifting campaign simultaneously;
The 5th step, complete after the search cycle, scanning mechanism is adjusted in pitch orientation to the extreme lower position of corresponding mode of operation, prepare to start the spiral scan in next cycle.
Compared with prior art, good effect of the present invention is: by scanning mechanism is prepended to the initial position of corresponding mode of operation in scanning motion, then respectively on azimuth direction and pitch orientation on according to the sweep velocity setting and movement locus, complete the scanning search campaign of one-period, reduce the prescan time of pitch orientation, thereby improved scan efficiency.The inventive method has realized the quick all direction searching of LONG WAVE INFRARED optical system under low, high-altitude pattern.
