Embodiment Construction

[0038] In order to make the solution of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0039] Such as figure 1 As shown, a coaxial optical dual-camera splicing structure includes: a camera connecting plate 3, a cylindrical pin 4, a main load-bearing structure 5, and a supporting structure 6;

[0040] The camera A1 and the camera B2 are connected to the camera connection plate 3 with screws through their respective main load-bearing structures 5 , and are positioned by cylindrical pins 4 . Finally, the dual cameras are connected to the support structure 6 after being assembled. There is a certain angle between the optical axes of camera A1 and camera B2, such as figure 2 As shown, the angle is measured at the early stage of structure assembly and adjusted in real time. After the adjustment is in place, the cylindrical pin 4 is prepared, and the subsequent two camer...

Abstract

The invention discloses a coaxial optical dual-camera splicing structure. According to the scheme, a screw mechanical connection is adopted to enable main support structures of two high-resolution cameras to be fixedly connected together, so that an included angle between optical axes of the two cameras is ensured and splicing of the two cameras is achieved. Through support structures, a dual-camera combination is fixed to a satellite platform, and the problem of thermo-mechanical coupling between the cameras and the satellite platform is solved; and the internal connecting part of the two cameras is provided with a reset pin, and the relative positional relationship between the cameras is ensured at the initial stage of structure assembly by preparing pins. Compared with the prior art, the coaxial optical dual-camera splicing structure is light in weight, good in rigidity and convenient to assembly, the precision and stability of the included angle between the two cameras are high, the stability of an on-orbit geometry is good, large and wide functions are realized at a small cost, and great significance is achieved in realizing the high resolution and wide coverage of space remote sensing cameras.

Description

technical field [0001] The invention belongs to the technical field of aerospace optical remote sensors, and relates to a coaxial optical double-camera splicing structure, in particular to a dual-camera mechanical-thermal integration configuration. Background technique [0002] With the development of aerospace optical remote sensing technology, cameras are gradually developing towards high resolution and wide coverage. However, for the same aerospace optical remote sensing camera, resolution and frame width are two technical indicators that are difficult to balance. In order to achieve a large width, modern high-resolution cameras often adopt a multi-camera stitching layout. [0003] At present, the most commonly used method is to assemble multiple cameras on the satellite platform after the development of each, and rely on the hole position tolerance and shape of the mounting plate to ensure the azimuth relationship between the cameras. Usually, precise measurement and adj...
