Description
Technical Field
The invention relates to the field of spectral imaging, in particular to a system and a method for spectrum time-sharing detection based on visual field gating, which are mainly applied to spectral imaging guidance and detection.
Background
The target detection and identification technology based on multispectral imaging has wide application prospect and research value in the fields of early warning and reconnaissance, accurate guidance, target hyperspectral characteristic acquisition and the like. At present, the existing multispectral imaging technology mainly comprises multi-channel imaging, multicolor device imaging and spectral spectroscopic imaging, and the three multispectral imaging modes have certain defects in the aspects of technical indexes such as spectral resolution, imaging frame frequency, equipment weight and volume and the like. In the field of spectrum detection and accurate guidance, the spectrum cooperative detection equipment with wide wave band, fast response, small volume and low power consumption is a trend of future development.
The multispectral scene information comprises a multidimensional database of multispectral targets, interference and background radiance characteristics in the battle scene, and is called a multispectral data cube. The database is a four-dimensional data cube containing the two-dimensional geometric properties of the target, interference, background, radiation intensity properties and spectral properties. The spectral distribution of different pixels in a multispectral scene has differences, and the image data of each spectral band should have spatial consistency and temporal consistency. The sparse spectral information is a sparse four-dimensional database consisting of the radiation intensity characteristics and the spectral characteristics of certain regions in a selected scene, and is called a sparse multispectral data cube.
The patent CN104535186B discloses a moving platform infrared spectrum correlation detection system and a method, the invention utilizes a two-dimensional servo-actuated system to control the center pointing of a broadband optical system, realizes target detection, tracking and spectral measurement under the condition of a moving platform, can effectively isolate the disturbance of the moving platform to the system, and simultaneously realizes scene imaging and local area spectral measurement through spectroscope light splitting. However, the above patent shows that the spectral measurement can be performed only when the target is locked at the center of the field of view, and the measurement area is in principle within 5 pixels of the center of the field of view, so that when the multi-target spectral measurement is performed, a servo-action is performed to lock one target first, the spectral measurement of the target is completed, and then the spectral measurement of the next target is performed in sequence, the response speed of the spectral measurement is slow, the measurement range is the center of the field of view, and the area is limited. To avoid the above disadvantages, a system and method for atlas detection based on view gating are proposed.
