Embodiment Construction
[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0045] A specific implementation structure of a space panoramic imaging system, such as figure 1 As shown, it includes a satellite payload manager, a camera controller, and 5 cameras (camera 1 to camera 5, code-named 1, 2, 3, 4, 5) and a camera controller 6 (Note: for easy understanding and description, this embodiment uses 5 cameras to illustrate the present invention, but the present invention is not limited to 5 cameras).
[0046] The satellite load manager sends exposure mode instructions to the camera controller through RS422, and the exposure mode instructions include exposure mode, exposure time, satellite time information, satellite attitude parameters, and satellite speed and altitude;
[0047] The signals between the camera controller and the 5 cameras include synchronization signals and RS422 communication. The synchronization signals are sent fro...

The invention relates to a space panoramic imaging system and an imaging method. According to the characteristics of space panoramic imaging, one controller is adopted to control synchronous exposureof a plurality of cameras; a main camera is determined according to the attitude of the satellite; according to the speed and height of the satellite and the focal length information of the main camera, the maximum exposure time limit of the main camera is controlled, and the exposure time of other cameras is controlled by utilizing the exposure time of the main camera, so that all the cameras aresynchronously exposed, synchronous shooting work is realized, the panoramic image of the celestial body target is finally reconstructed, and the problems that the panoramic image is difficult to splice and the image is blurred in the prior art are solved.
Description
technical field [0001] The invention belongs to the field of optical imaging, and in particular relates to a space panoramic imaging system and an imaging method. Background technique [0002] Space panoramic imaging is used for panoramic imaging of the earth from space, and generally consists of multiple cameras, such as figure 1 Shown is a space panoramic imaging system composed of multiple cameras, which are installed on multiple surfaces of the satellite for panoramic imaging of the earth from space [0003] The traditional panoramic camera exposure method is generally that each camera performs its own exposure according to the built-in automatic exposure algorithm, and then outputs its own image. After adjusting the contrast and brightness of the output image, the images of several cameras are combined into a panoramic image. Get a panoramic photo or video of the target scene. This method is used for ground applications. It can achieve better results for scenes where ...
