Through the description of the specific implementation manners, a more in-depth and specific understanding of the technical means and effects adopted by the present invention to achieve the predetermined purpose can be obtained. However, the attached drawings are only for reference and illustration, and are not used to limit the present invention.
[0021] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the present invention is described in detail below in conjunction with the attached drawings and preferred embodiments.
[0022] Figure 1 Flow chart of the test method for a satellite remote sensing camera in an embodiment of the present invention.
[0023] As Figure 1 shown, the test method for the satellite remote sensing camera provided in this embodiment includes the following steps:
[0024] Step S11: Obtain orbital information and satellite imaging tasks.
[0025] Specifically, orbital data is obtained through the input information and / or network, and orbital information is generated based on the orbital data; satellite imaging data is obtained according to the input information and / or received data, and a satellite imaging task is generated based on the satellite imaging data. The satellite imaging task can be a single imaging task or multiple imaging tasks. The satellite imaging task includes one or more of the data length of the satellite imaging task, the checksum of the satellite imaging task, the number of tasks, and the imaging task. The imaging task includes one or more of the task mode, the payload imaging time, the required duration of payload imaging, the imaging attitude information, and the payload imaging parameters. The payload imaging parameters include one or more of the frame rate, exposure time, resolution, band, dynamic range, signal-to-noise ratio, saturation, color space, and data format. The imaging attitude information can be the estimated longitude, latitude, and altitude, or the set information such as the satellite pitch angle and roll angle planned on the ground.
[0026] Specifically, in one implementation manner, satellite timing is performed according to the orbital information to ensure that each step in the test matches the actual state of the satellite.
[0027] Specifically, in one embodiment, orbit information and satellite imaging tasks are obtained according to the set information queue.
[0028] Step S12: Verify the satellite imaging task based on the orbit information.
[0029] Specifically, step S12 includes verifying whether the orbit information meets the orbit requirements and time window requirements required by the satellite imaging task, verifying whether the format of the payload imaging parameters or other data of the satellite imaging task conforms to the preset format. When it is verified that the orbit information meets the orbit requirements and time window requirements required by the satellite imaging task, and the format of the payload imaging parameters or other data of the satellite imaging task conforms to the preset format, it is determined that the satellite imaging task verification passes. When it is verified that the orbit information does not meet the orbit requirements and time window requirements required by the satellite imaging task, and / or the format of the payload imaging parameters or other data of the satellite imaging task does not conform to the preset format, it is determined that the satellite imaging task verification fails. After generating the reason for the verification failure, return to step S11 to re-obtain the satellite imaging task.
[0030] Step S13: When the satellite imaging task verification passes, perform satellite attitude simulation maneuvers according to the satellite imaging task.
[0031] Specifically, obtain the payload imaging time and imaging attitude information according to the satellite imaging task. At a period of time before the payload imaging time (for example, 10 minutes before the payload imaging time), record the current attitude of the satellite as the pre-imaging attitude of the satellite, and simulate and adjust the attitude parameters such as the pitch, roll, and yaw of the satellite according to the imaging attitude information so that the attitude of the satellite meets the imaging requirements; at a period of time after the payload imaging time (for example, 10 minutes after the payload imaging time), simulate and adjust the attitude parameters such as the pitch, roll, and yaw of the satellite according to the pre-imaging attitude to prepare for the next task. This can ensure that the satellite can maintain good attitude control when continuously executing multiple tasks.
[0032] Step S14: Send the satellite imaging task to the satellite minimization module.
[0033] Specifically, send the satellite imaging task to the satellite minimization module so that the satellite minimization module performs imaging according to the satellite imaging task.
[0034] Specifically, in one embodiment, the satellite imaging task is signal-converted and then sent to the satellite minimization module.
[0035] Step S14: Obtain the imaging data fed back by the satellite minimization module, and parse and process the image data.
[0036] Specifically, operations such as decompressing the imaging data fed back by the satellite minimization module, restoring the original image format, etc. are performed, and data packetization is carried out to organize the imaging data into a processable structure. Further operations such as correction, pseudo-color synthesis, stripe removal, and distortion correction are performed on the packetized imaging data to improve the image quality.
[0037] Specifically, after step S14, it includes determining whether all satellite imaging tasks are completed. If so, it is determined whether all the set information queues are completed; if not, attitude parameters such as pitch, roll, and yaw of the satellite are simulated and adjusted according to the uncompleted satellite imaging tasks, and a continue test instruction is sent to the satellite minimization module so that the satellite minimization module performs imaging according to the uncompleted satellite imaging tasks.
[0038] Specifically, after determining whether all the set information queues are completed, if all the set information queues are completed, the test is ended; if not all the set information queues are completed, return to step S11 to obtain orbit information and satellite imaging tasks according to the uncompleted information queues.
[0039] The test method for the satellite remote sensing camera provided by the present invention generates orbit information to verify the satellite imaging tasks. When the satellite imaging tasks pass the verification, satellite attitude simulation maneuvers are performed according to the satellite imaging tasks, and the satellite imaging tasks are sent to the satellite minimization module so that the satellite minimization module performs imaging according to the satellite imaging tasks, obtains the imaging data fed back by the satellite minimization module, and analyzes and processes the image data. It can realize full-automatic, full-process, and high-efficiency ground segment function tests of the remote sensing camera during the integrated satellite desktop joint test stage, making the ground test of the satellite no longer dependent on physical devices such as attitude and orbit control single machines and semi-physical simulation platforms, effectively utilizing general ground computing resources, and having the characteristics of low cost, high reliability, simple setup, convenient operation, and high test efficiency.

[0045] Specifically, when the orbit information does not meet the required orbit requirements and time window requirements of the satellite imaging task, and / or receives the first verification failed instruction sent by the dynamics module 211, the remote sensing payload comprehensive measurement module 214 generates a verification failed prompt message and the reason for failure, and re-obtains the satellite imaging data according to the input information and / or received data.
