[0020] The calibration device for improving unmanned aerial vehicle throwing precision includes calibration main body 1, first level 2, second level 3 and collimator 4, the first level 2, second level 3 and collimator 4 are respectively installed on the calibration main body 1, and the optical axis of the collimator 4 is perpendicular to the reference surface A of the calibration main body 1 by special tooling, when the reference surface normal of the calibration main body 1 is perpendicular to the ground, the bubble position of the first level 2 and the second level 3 is adjusted to the center;When correcting unmanned aerial vehicle, the calibration main body 1 is installed at the back of the throwing pod platform 6, and the photoelectric aiming pod 7 is aligned with the collimator 4.

[0021] Preferably, multiple groups of mounting holes or waist-shaped holes are reserved on the calibration main body 1 to meet the connection of the throwing pod platform 6 of different models. Wherein, the specific structure form of calibration main body 1 is not limited to the structure form in Figure 1 As long as the calibration device for improving unmanned aerial vehicle throwing precision can transfer the reference mounting surface of throwing pod platform 6 to the reference surface A of the calibration device during the adjustment process, and can correct the optical axis of collimator 4 perpendicular to the reference surface A of the calibration device.

[0022] Preferably, the photoelectric collimating pod 7 has collimating scales, and the collimating telescope 4 has target scales. The collimating scales in the photoelectric collimating pod 7 are adjusted to be consistent with the target scales in the collimating telescope 4, so as to ensure that the normal line of the reference installation surface of the launching pod platform 6 (i.e. the launching bin ejection axis) is parallel to the collimating optical axis of the photoelectric collimating pod 7.

[0023] Preferably, the back surface of the launching pod platform 6 is the reference installation surface of the launching pod platform 6.

[0024] In the present embodiment, the calibration device is adjusted by a special tool to ensure that the normal line of the installation reference surface A of the calibration device is perpendicular to the ground plane, and then two levels are fixedly installed on the calibration device, and the bubble positions of the first level 2 and the second level 3 are adjusted to be centered. The normal direction of the reference installation surface of the launching pod platform 6 is corrected by the levels fixedly installed on the device, so as to be perpendicular to the ground plane.

[0025] In the present embodiment, after the calibration device corrects the normal line of the reference installation surface of the launching pod platform 6 to be perpendicular to the ground plane, the inertial measurement unit IMU of the unmanned aerial vehicle is calibrated; and in the subsequent launching of objects by the launching bin 8, the normal line of the reference installation surface of the launching pod platform 6 (i.e. the launching bin ejection axis) is ensured to be perpendicular to the ground plane.

Therefore, the corrected unmanned aerial vehicle effectively ensures that the central optical axis of the photoelectric aiming pod 7 is perpendicular to the ground during the free fall throwing process of the throwing bin 8, and the throwing precision of the unmanned aerial vehicle is improved.

[0028] The calibration device for improving unmanned aerial vehicle throwing precision provided by the utility model is applied to the calibration of the photoelectric aiming pod and the reference installation surface of the throwing pod platform of the unmanned aerial vehicle in the free fall throwing mode. Through the calibration device, the normal line of the reference installation surface of the throwing pod platform (namely the exit axis of the throwing bin) can be corrected to be perpendicular to the ground plane, and then the correction of the inertial measurement unit IMU of the unmanned aerial vehicle is carried out in this state. Meanwhile, the calibration device can also correct the normal line of the reference installation surface of the throwing pod platform (namely the exit axis of the throwing bin) to be parallel to the aiming optical axis of the photoelectric aiming pod. The corrected unmanned aerial vehicle effectively ensures that the normal line of the reference installation surface of the throwing pod platform (namely the exit axis of the throwing bin) and the central optical axis of the photoelectric aiming pod are perpendicular to the ground during the free fall throwing process of the throwing pod platform, and the throwing precision of the unmanned aerial vehicle is improved.
