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 combined. 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 camera...

Abstract

The invention discloses a splicing structure of a coaxial optical double camera. The solution adopts a screw mechanical connection method to securely connect the main supporting structures of two high-resolution cameras, thereby ensuring the angle between the optical axes of the two cameras and realizing Stitching of two cameras. Then, through the support structure, the dual-camera assembly is fixed on the satellite platform, which solves the problem of thermal coupling between the camera and the satellite platform. The internal connection part of the dual-camera is equipped with a reset pin, and the method of preparing pins is used to ensure the inter-camera contact at the initial stage of structural assembly. Relative positional relationship. Compared with the prior art, the present invention has light weight, good rigidity, convenient assembly, high accuracy and stability of the included angle between the two cameras, and good geometric stability on the track. The high resolution and wide coverage of aerospace remote sensing cameras are of great significance.

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...
