The invention belongs to the technical field of camera equipment, and discloses a calibration device and a satellite-borne camera. The objective of the invention is to solve the problem that the existing calibration device is poor in locking effect in a closed state and disturbs a calibration plate in an unfolded state. The calibration device comprises a calibration plate, a fixing mechanism and a control mechanism, the calibration plate is connected with the end part of the light shield, and the calibration plate can be unfolded or closed along the edge of the light shield; the fixing mechanism comprises a positioning structure and a locking structure, the positioning structure is used for limiting the movement of the calibration plate on the light shield in a closed state, the locking structure is used for limiting the rotation of the calibration plate on the light shield in the closed state, and the calibration plate is firmly fixed in the closed state; the control mechanism is connected with the calibration plate; the power source is connected with the self-locking speed reduction transmission structure, the power source can drive the self-locking speed reduction transmission structure to drive the calibration plate to be self-locked after the calibration plate is unfolded to the preset position on the light shield, certain rigidity is achieved after the calibration plate is unfolded, and the imaging effect is improved.

    本发明属于摄像设备的技术领域,公开了一种定标装置及星载相机。旨在解决现有的定标装置闭合状态锁定效果差,展开状态对定标板产生扰动的问题。定标装置,包括:定标板、固定机构和控制机构;定标板与遮光罩的端部连接,且定标板能够沿遮光罩的边沿展开或者闭合;固定机构包括定位结构和锁紧结构,定位结构用限制定标板于遮光罩上处于闭合状态下的移动,锁紧结构用于限制定标板于遮光罩上处于闭合状态下的转动,将定标板在闭合状态下进行牢固的固定;控制机构与定标板连接;动力源与自锁减速传动结构连接,动力源能够驱动自锁减速传动结构带动定标板于遮光罩上处于展开至预设位置后自锁,在展开后具有一定刚度,提高成像效果。
