Embodiment Construction

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0042] The present invention uses an area array detector to perform a multi-channel TDI imaging method. Specifically, the area array detector is a CMOS image sensor. Compared with the CCD image sensor carried by the previous remote sensing satellite, the photoelectric conversion principle of the CMOS sensor is the same, but the CCD adopts one by one. The photosensitive output can only be output according to the specified program, and the ...

Abstract

The invention provides a multi-channel TDI imaging method based on an area array detector, wherein the area array detector includes a full spectrum window and at least one target spectrum window; The starting line position and number of lines of each spectral segment window on the area array detector; calculate the image plane line frequency, adjust the imaging frame frequency of the area array detector to match the line frequency; control the area array detection by external triggering The continuous image sequence of each window is obtained; the image sequence is accumulated according to the corresponding pixel to obtain the image of each spectrum. The method provided by the invention realizes the multi-channel TDI push-broom imaging function on a single area array detector, establishes a strict relationship between the integral series, the frame frequency and the image shift frequency, and can flexibly configure the integral series and the frequency of each channel. Push-broom imaging parameters such as line frequency.

Description

technical field [0001] The invention belongs to the technical field of optical remote sensing imaging, and relates to an imaging method based on an area array detector, in particular to a method capable of flexibly realizing multi-channel TDI imaging. Background technique [0002] Imaging detectors are very important imaging photosensitive elements, mainly including CCD (Charge-coupled Device) and CMOS (Complementary Metal Oxide Semiconductor) two categories. The charge information stored by the CCD needs to be read after being transferred bit by bit under the control of the synchronization signal. The charge information transfer and read output need to be matched by a clock control circuit and different power supplies. The entire circuit is complex and slow. . The CMOS sensor directly outputs digital signals after photoelectric conversion, the signal reading is very simple, and the image information of each unit can be processed at the same time. In recent years, with the...
