Description

Technical Field

[0001] This invention belongs to the field of satellite visual measurement and data acquisition technology, and relates to a satellite dataset acquisition system and method. Specifically, it relates to a dataset acquisition system and method that acquires satellite image data through camera imaging and uses a robotic arm to adjust the camera attitude to construct a controllable simulated space imaging environment under ground conditions. Background Technology

[0002] With the development of aerospace and space robotics technologies, technologies such as satellite recognition, positioning, and attitude measurement based on visual information have gradually become key supporting technologies for on-orbit servicing, space operations, and autonomous spacecraft operation. The research and verification of these technologies typically rely on large datasets of high-quality satellite images for algorithm training, testing, and evaluation.

[0003] Existing satellite vision datasets mainly originate from numerical simulations or in-orbit measured data. While simulation datasets generated using computer graphics methods offer advantages such as high generation efficiency and strong controllability, their imaging processes still differ from the real physical environment. This makes it difficult to accurately reflect the imaging characteristics of real satellites under complex lighting conditions, resulting in domain differences between simulation and real data and affecting the generalization performance of vision algorithms in practical applications. In-orbit measured data acquisition is constrained by high mission costs, limited acquisition conditions, and the non-reproducibility of data, making it difficult to meet the demands for data scale and diversity in algorithm development.

[0004] To bridge the gap between purely simulated data and real data, some studies have attempted to construct experimental environments using physical satellite models and imaging equipment on the ground, acquiring image data by photographing the satellite models. However, existing ground acquisition schemes typically suffer from low system integration and insufficient control over environmental conditions, making it difficult to uniformly control lighting conditions, imaging angles, and the acquisition process. Furthermore, the acquisition process largely relies on manual operation, with camera attitude adjustment and data acquisition lacking automation and repeatability, resulting in low data consistency and acquisition efficiency, and hindering the formation of standardized, large-scale datasets.

[0005] Furthermore, existing solutions rely on a limited range of camera attitude adjustment methods, making it difficult to achieve multi-view, multi-attitude data acquisition while maintaining imaging stability. This restricts the applicability of the datasets in satellite vision missions. Therefore, there is an urgent need for a satellite dataset acquisition system and method that can simulate the space imaging environment under ground conditions and achieve automatic camera attitude adjustment and unified data acquisition, thereby improving the controllability, repeatability, and practicality of data acquisition. Summary of the Invention

[0006] To address the problems of existing satellite vision datasets, which mainly rely on simulation generation or on-orbit measured data, low integration of ground acquisition systems, insufficient controllability of imaging environments, and low automation of camera attitude adjustment and data acquisition processes, this invention provides a satellite dataset acquisition system and method based on ground-space environment simulation. By constructing a controllable simulated space imaging environment under ground conditions and using a robotic arm to adjust the camera attitude, the system achieves automated and repeatable acquisition of satellite image data, thereby providing stable and reliable dataset support for satellite vision missions.

[0022] Step 5, Data Recording: Record and store the satellite image data acquired by the camera acquisition unit;

[0023] Step 6, Loop Acquisition: Repeat steps 3 and 4 to complete multi-view, multi-pose data acquisition.

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings, but it is not limited thereto. Any modifications or equivalent substitutions to the technical solution of the present invention that do not depart from the spirit and scope of the technical solution of the present invention should be covered within the protection scope of the present invention.

[0040] This invention addresses the problems of existing satellite visual datasets, which mainly rely on simulation-generated or on-orbit measured data, low integration of ground acquisition systems, insufficient controllability of the imaging environment, and low automation of camera attitude adjustment and data acquisition processes. It provides a satellite dataset acquisition system based on ground-space environment simulation, such as... Figure 1-8 As shown, the system includes a satellite physical model unit, a simulated space environment construction unit, an attitude and position adjustment unit, a camera acquisition unit, and a data acquisition and control unit. Each unit works collaboratively under the unified coordination of the data acquisition and control unit to construct a controllable simulated space imaging environment and complete the acquisition of satellite image data.

[0041] The satellite physical model unit is used to simulate the shape, structure, and visual characteristics of a real satellite under ground conditions;

[0042] The simulated space environment building unit is used to simulate environmental conditions related to space imaging under ground conditions;

[0043] The attitude and position adjustment unit is used to adjust the spatial position and attitude of the camera relative to the satellite physical model;

[0044] The camera acquisition unit is used to image the satellite physical model under different attitudes and environmental conditions to acquire satellite image data;

[0045] The data acquisition and control unit is used to uniformly control the satellite physical model unit, the simulated space environment construction unit, the attitude and position adjustment unit, and the camera acquisition unit, so as to realize the configuration of acquisition parameters, the control of the acquisition process, and the recording and storage of image data.

[0046] In this invention, the satellite physical model unit is used to physically simulate the shape, structure, and visual characteristics of a real satellite under ground conditions. Its overall structure is designed and assembled according to the proportions of the target satellite. For example... Figure 2 As shown, the main structure of the satellite physical model unit is made of carbon fiber plates. Carbon fiber plates are lightweight, high-rigidity, and structurally stable, which can reduce the impact of structural deformation on imaging results while ensuring the overall strength of the model. The detailed components of the satellite physical model unit adopt a modular design. Among them, components with obvious external features, such as the nozzle structure, are formed by 3D printing and then surface-treated by painting to simulate the color and reflective properties of a real satellite surface. Special components with clear geometric features and metallic texture requirements, such as the docking ring, are made of metal materials to enhance the structural accuracy and visual consistency of the model in key parts. The solar panels on both sides of the satellite are made of printed polypropylene plates and are installed on both sides of the main structure through pivots or fixed connections to simulate the solar deployment structure of a real satellite. After the assembly of all components is completed, the overall exterior of the satellite physical model unit is covered with gold aluminum foil to simulate the appearance of multi-layered heat insulation materials commonly found on satellites in the space environment, thus presenting a visual effect similar to that of a real satellite under visible light and specific imaging conditions. Through the above structural design and material combination, the satellite physical model unit can realistically reproduce the satellite's outline, key structural features and overall visual characteristics in a ground-based simulated space imaging environment, providing a reliable physical carrier for subsequent image data acquisition.

[0047] In this invention, the simulated space environment construction unit is used to simulate environmental conditions related to space imaging under ground conditions, providing a stable and controllable imaging background and lighting environment for image acquisition from the satellite physical model. This simulated space environment construction unit mainly includes a darkroom environment construction section and a lighting simulation section. The darkroom environment construction section consists of a closed or semi-closed darkroom space, with a large area of ​​green screen material laid and covered inside to form a uniform, low-texture background environment. The green screen background effectively isolates external ambient light from interfering with the imaging process and facilitates subsequent background separation or data processing of the acquired images, thereby improving the usability and consistency of the satellite image data. The lighting simulation section includes at least one set of full-band light sources to simulate the illumination conditions in the space environment where the sun is the primary light source. In specific implementations, the lighting simulation section can use two full-band lamps, respectively arranged at different locations on the satellite physical model, to achieve combined adjustments of different incident angles and light intensities. By adjusting the on / off status, brightness, and spatial position of each full-band light fixture, imaging scenarios under different solar altitude angles, azimuth angles, and light intensity conditions can be simulated. Furthermore, the simulated space environment construction unit also includes a reflector for secondary reflection or supplementary lighting adjustment of the full-band light source. By changing the position, angle, or reflective area of ​​the reflector, diverse lighting distribution patterns can be further constructed, thereby simulating complex lighting conditions that may occur in space imaging, such as strong light, weak light, side lighting, or localized high reflectivity. Through the synergistic construction of the darkroom background and lighting simulation described above, this invention enables the creation of a repeatable and adjustable simulated space imaging environment under terrestrial conditions.

[0048] In this invention, the arrangement diagram of the simulated space environment construction unit and the satellite physical model is as follows: Figure 3 As shown, from a top-down perspective, the simulated space environment construction unit forms an approximately rectangular imaging area enclosed by a green screen. The satellite physical model unit is positioned at the center of this rectangular imaging area, ensuring it is within a relatively symmetrical imaging space in all directions. This facilitates image acquisition of the satellite physical model from different perspectives. Illumination simulation devices for simulating sunlight are arranged at the corners of the rectangular imaging area to create illumination conditions with different incident directions. Furthermore, reflectors are placed within or around the rectangular imaging area; their position and orientation can be adjusted or moved according to acquisition needs. These reflectors reflect and compensate for light from a full-spectrum light source to create different illumination distribution patterns. Through this arrangement, various illumination environments related to space imaging can be flexibly simulated under ground conditions.

[0049] In this invention, the attitude and position adjustment unit is used to adjust the spatial position and attitude of the camera acquisition unit relative to the satellite physical model, so as to realize multi-view and multi-attitude image acquisition. In a specific implementation, the attitude and position adjustment unit includes a robotic arm with multiple degrees of freedom, which can realize position movement and attitude adjustment in three-dimensional space.

[0050] In this invention, the camera acquisition unit is installed at the end effector of the robotic arm and forms an integrated motion and acquisition structure with the robotic arm.

[0051] In this invention, the camera acquisition unit is used to image a satellite physical model under different spatial locations, shooting angles, and simulated space environments, thereby acquiring satellite image data. Through the motion control of the robotic arm, the camera acquisition unit can perform multi-angle scanning or fixed-point shooting around the satellite physical model to meet the diverse data requirements of different satellite vision tasks.

[0052] In this invention, during data acquisition, the attitude and position adjustment unit is communicatively connected to the data acquisition and control unit, which uniformly schedules and controls the robotic arm's trajectory, speed, and target attitude. When the camera acquisition unit reaches the preset position and attitude, it triggers the camera to complete the image acquisition operation, thus achieving coordinated operation between camera attitude adjustment and image acquisition. Through this structure and control method, the automation and repeatability of satellite image data acquisition can be improved while ensuring acquisition stability.

[0053] In this invention, the data acquisition and control unit is used to uniformly control the satellite physical model unit, the simulated space environment construction unit, the attitude and position adjustment unit, and the camera acquisition unit, so as to realize the configuration of acquisition parameters, the scheduling of the acquisition process, and the recording and storage of image data. In a specific implementation, the data acquisition and control unit includes a host computer control system, which establishes a communication connection with the robotic arm control system and the camera acquisition unit through a communication interface.

[0054] In this invention, the host computer control system has a visual software interface for providing operators with functions such as configuring acquisition parameters, displaying system operating status, and controlling the acquisition process. Through the software interface, operators can set the camera's imaging parameters, the robotic arm's motion parameters, and data acquisition-related parameters, and control the start, pause, or termination of the acquisition task. During the acquisition process, the host computer control system coordinates the robotic arm's movement with the camera's trigger timing, ensuring that the camera acquisition unit completes the image acquisition operation after reaching the preset spatial position and posture.

[0055] In this invention, the data acquisition and control unit is also used for unified management of the acquired satellite image data, including recording, classifying, and storing the image data. Image data generated during the acquisition process can be named and saved according to preset rules to form a structured satellite image dataset. Through the aforementioned host computer software interface and control logic, centralized control of multi-unit collaborative work is achieved, improving the automation level and system integration of the satellite dataset acquisition process in a simulated space environment.

[0056] In this invention, such as Figure 5 As shown, in specific implementation, the software system of the host computer control system adopts a modular architecture design. Its functional modules include at least a parameter configuration module, a device communication module, a motion and acquisition scheduling module, a data management module, and a status monitoring and display module. The interface diagram of the host computer control system software is shown below. Figure 6 As shown, the parameter configuration module is used to uniformly configure various parameters required during data acquisition, including camera imaging parameters, robotic arm motion parameters, and acquisition task-related parameters. Through this module, the operator can flexibly adjust the system operating parameters according to different acquisition needs to adapt to data acquisition tasks under different satellite models, imaging distances, and lighting conditions. The device communication module is used to realize data communication and command interaction between the host computer control system, the robotic arm control system, and the camera acquisition unit. This module manages the connection status of external devices and completes the sending of control commands and the receiving of device feedback information, thereby ensuring stable communication between the hardware units. The motion and acquisition scheduling module coordinates the working sequence of the attitude and position adjustment unit and the camera acquisition unit. During acquisition, this module plans the robotic arm's motion path according to the preset acquisition task and triggers image acquisition after the camera acquisition unit reaches the preset spatial position and attitude, thus achieving synchronous control of the robotic arm's motion and image acquisition process. The data management module manages and stores the acquired satellite image data. The data management module can name, classify, and save image data according to preset rules, thereby forming a structured satellite image dataset, which facilitates subsequent data retrieval, processing, and analysis. The status monitoring and display module is used to display the system's operating status in real time on the host computer software interface, including the robotic arm's operating status, camera's working status, and the progress of the acquisition task. Through this status monitoring and display module, operators can intuitively understand the system's operation and adjust or intervene in the acquisition process when necessary.

[0057] In summary, the workflow of a ground-based satellite data acquisition system simulating a space environment is as follows: Figure 7 The specific steps are as follows:

[0058] Step 1: After system startup, the data acquisition and control unit initializes the satellite physical model unit, the simulated space environment construction unit, the attitude and position adjustment unit, and the camera acquisition unit, and establishes communication connections between the host computer control system, the robotic arm control system, and the camera acquisition unit. The operator configures the acquisition parameters, including camera imaging parameters, robotic arm motion parameters, and acquisition task-related parameters, through the software interface of the host computer control system.

[0059] Step Two: After parameter configuration, the simulated space environment construction unit enters the working state, constructing a preset simulated space imaging environment through a darkroom environment and lighting simulation device. Subsequently, under the scheduling of the data acquisition and control unit, the attitude and position adjustment unit controls the robotic arm to drive the camera acquisition unit to move to the preset spatial position and attitude.

[0060] Step 3: Once the camera acquisition unit reaches the target position and attitude, the data acquisition and control unit triggers the camera acquisition unit to image the satellite physical model, acquiring satellite image data under the corresponding viewing angle and lighting conditions. After acquisition, the image data is recorded and stored by the data acquisition and control unit.

[0061] Step 4: After completing one image acquisition, the system repeats the camera attitude adjustment and image acquisition process according to the preset acquisition task plan to achieve satellite image data acquisition under multiple viewing angles, attitudes, and lighting conditions. After all acquisition tasks are completed, the system automatically ends the current acquisition process and enters standby mode, waiting for the start of the next acquisition task.

[0062] Through the above workflow, this invention realizes the automated and systematic acquisition of satellite image data under ground conditions, improving the controllability, repeatability, and efficiency of the satellite image data acquisition process.

[0063] The ground-based satellite dataset acquisition system in a simulated space environment of the present invention can be applied to the research and development and verification stage of satellite vision mission-related algorithms, and is especially suitable for scenarios where satellite pose estimation, target recognition, visual navigation and other missions require image datasets.

[0064] Example:

[0065] In this embodiment, the satellite physical model unit is installed within the darkroom imaging area formed by the simulated space environment construction unit, with the satellite physical model positioned at the center of a rectangular imaging area enclosed by a green screen. By adjusting the position and state of the full-band light source and reflector in the simulated space environment construction unit, simulated space imaging environments with different lighting directions and intensities are constructed to simulate various imaging conditions that a satellite may encounter in space. Before data acquisition, the operator configures the acquisition task through the host computer control system in the data acquisition and control unit, including camera imaging parameters, robotic arm motion trajectory parameters, and the number of acquisitions. After the parameter settings are completed, the system enters automatic acquisition mode. During the acquisition process, the attitude and position adjustment unit controls the robotic arm to drive the camera acquisition unit, moving it around the satellite physical model at multiple angles and in multiple attitudes according to a preset trajectory. When the camera acquisition unit moves to the designated spatial position and attitude, the data acquisition and control unit triggers the camera to complete the image acquisition operation. The acquired satellite image data is uniformly recorded and stored by the data acquisition and control unit. By repeating the above process, multi-view satellite image data can be acquired under different camera attitudes, different observation distances, and different lighting conditions, thereby constructing a structured satellite image dataset. This dataset can be directly used for training, testing, or comparative analysis of satellite vision algorithms.

[0066] The ground-based simulated space environment satellite data acquisition system of this invention can acquire satellite image data with high realism and consistency (e.g., [data missing]) without the need for actual on-orbit testing. Figure 8 As shown in the figure, it significantly reduces data acquisition costs, improves data acquisition efficiency, and provides reliable data support for the research and development of satellite vision-related technologies.
