Method for obtaining spectrum-integrated time-varying target optical spectrum information and device thereof

Abstract

The invention discloses a method for obtaining spectrum-integrated time-varying target optical spectrum information and a device thereof. The method specifically comprises the steps of: obtaining a current frame image of a scene; extracting candidate interest regions which comprises time-varying targets therein; respectively leading the each candidate interest region to be associated with each interest region obtained from the last frame; confirming the candidate interest regions which are successfully associated to be interest regions; assigning the identification of the interest regions to the identification of the last frame interest region which is successfully associated therewith; and obtaining optical spectrum data of the each interest region of the current image. The invention also designs a device for realizing the method, which comprises a main control unit, an imaging sensor, an optical spectrum sensor, an infrared spectroscopy lens, a tracking reflecting mirror and a tracking and scanning rotary table. The invention provides a data acquisition method for combining a wide imaging optical spectrum with a wide non-imaging optical spectrum; and compared with a normal method for acquiring optical spectrum data of the all regions of the whole scene, has fast reaction speed and low cost, is suitable for the intellectualized acquisition of the time-varying target optical spectrum data, and improves the cost-effectiveness ratio for acquiring the optical spectrum date.

Description

technical field [0001] The invention belongs to the field of remote sensing, monitoring and spectral data collection, and in particular relates to a method and device for collecting spectral data of time-varying objects. Background technique [0002] Spectral data acquisition technology mainly studies the methods and techniques of acquiring spectral data of scenes or objects of interest. This technology is widely used in the field of remote sensing, and provides a data basis for studying the spectral characteristics of various target backgrounds, and then classifying, monitoring, and target detection and recognition of scenes. [0003] Usually, multispectral / hyperspectral imaging sensors are used for the collection of scene spectral data. The multispectral / hyperspectral imaging sensor has a certain field of view, angular resolution, and spectral resolution. The process of data acquisition by the multispectral / hyperspectral imaging sensor is to collect the scene area corresp...

AI Technical Summary

Problems solved by technology

[0005] For spectral data collection of time-varying objects, existing multispectral / hyperspectral imaging sensors have two disadvantages: (1) expensive; Its integration time is long and the response speed is slow, so it is not suitable for spectral data acquisition of time-varying objects
