Injection updating platform of satellite-borne real-time processing algorithm of remote sensing camera

Abstract

The invention provides an injection updating platform of a satellite-borne real-time processing algorithm of a remote sensing camera. A configuration control unit reads an image processing algorithm in a solidification storage unit, writes the image processing algorithm in a satellite-borne image real-time processing module, reads the image processing algorithm and writes the image processing algorithm in the satellite-borne image real-time processing module; the solidification storage unit stores the solidified image processing algorithm; a nonvolatile injection updating algorithm storage unit stores the image processing algorithm forwarded by an uploaded data receiving unit; the uploaded data receiving unit forwards an image processing algorithm configuration instruction and an injection updating instruction to the configuration control unit, and forwards the image processing algorithm to the nonvolatile injection updating algorithm storage unit; a satellite-borne camera data acquisition unit sends original image data to the satellite-borne image real-time processing module and sends target information data to the ground; and the satellite-borne image real-time processing module processes the original image data to obtain the target information data and original image background block data, and sends the target information data and the original image background block data to the satellite-borne camera data acquisition unit.

Description

technical field [0001] The invention belongs to the field of on-board real-time image processing, and proposes an on-board real-time processing algorithm update platform for remote sensing cameras, which can be used for real-time processing of on-orbit camera image data for target detection and recognition. Background technique [0002] With the continuous improvement of the resolution and width of remote sensing cameras, the amount of raw image data generated by remote sensing cameras has increased exponentially. Limited by the bandwidth of the satellite-ground link, it is impossible to transmit all the original data to the ground in time for further processing. It is necessary to rely on the on-board real-time processing algorithm to extract important target information data, significantly reduce the amount of data, and transmit effective image data from the satellite to the ground receiving station. Due to the higher and higher requirements for rapid response to remote s...
