Description

Technical field [0001] The invention relates to the technical field of remote sensing stereo imaging simulation, in particular to an asynchronous push-broom remote sensing stereo imaging simulation test system and a test method thereof. Background technique [0002] Asynchronous push-broom remote sensing stereo imaging is an important way to obtain remote sensing data, and has a wide range of applications in deep space exploration, land survey and other fields. Different from the usual binocular and multi-eye stereo imaging, asynchronous push-broom remote sensing stereo imaging is non-synchronous imaging, so the baseline distance, orbit height and camera position and attitude are not fixed, and the gradient vector changes of the three-dimensional terrain and landforms will cause push-broom stereo imaging. The lack of three-dimensional information in different regions of the imaging data has an impact on the accuracy and resolution of three-dimensional imaging, and brings difficul...

Problems solved by technology

Although this method can apply for remote sensing image data for the scientific research of asynchronous push-broom remote sensing stereo imaging, it has limitations.

It is mainly reflected in: First, although this method obtains real remote sensing image data, due to the limitation of authority level, it is difficult for some research institutions and individuals to obtain the required remote sensing image data to carry out scientific research; secondly, the applied remote sensing image is obtained by Spaceborne or airborne CCD (Charge Coupled Device, Charge Coupled Device) camera, the particularity and high cost of the data acquisition method make some experiments in scientific research unable to be effectively carried out, such as multiple orbits for specific areas Remote sensing imaging under altitude and multiple attitude angles, that is, the influence of CCD attitude and orbit six-degree-of-freedom changes on the resolution of asynchronous push-broom remote sensing stereo imaging, or the remote sensing of areas with different gradient changes in the state of CCD camera fixed attitude and orbit Comparative study of imaging, that is, the influence of topographic relief and gradient changes on the resolution of asynchronous push-broom remote sensing stereo imaging
