Atlas time-sharing detection system and method based on field-of-view gating

Abstract

The invention provides an atlas time-sharing detection method and system based on field-of-view gating, and the method comprises the steps: S1, scene information is input into an imaging detection channel and a spectrum detection channel through a field-of-view gating module in a time-sharing gating manner, and the full-field-of-view and broadband image information of a scene and the sparse spectrum information of the scene are obtained; S2, a target area recognition module recognizes a sensitive target area in the scene according to the full-view-field and broadband imaging information of the scene and the sparse spectral information of the scene; s3, the tracking control module controls the vision field gating module to dynamically gate the current sensitive target area to serve as the basis of vision field gating in a spectrum detection channel, current scene information serves as the basis of vision field gating in an imaging detection channel, the steps S1 to S3 are repeatedly executed, the area where the sensitive target is located in the vision field is dynamically recognized, and the spectral characteristics of the target area are tracked and detected in real time. The light path structure is simple and compact, the detection response speed is high, and the spectrum detection area is flexible and variable.

Problems solved by technology

However, the above-mentioned patent shows that spectral measurement can only be performed when the target is locked at the center of the field of view, and in principle the measurement area is within 5 pixels of the center of the field of view, so that when performing multi-target spectral measurement, it is necessary to perform servo maneuvers to lock one Target, after completing the spectral measurement of this target, the next target will be measured sequentially. The response speed of spectral measurement is slow, and the measurement range is the center of the field of view and the area is limited.
