Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of target calibration, in particular to a miniaturized self-positioning target device. BACKGROUND

[0002] For aiming equipment, target calibration is an important work that is directly related to aiming accuracy, and target calibration is mostly carried out by using a laser target calibration mirror, an optical target calibration mirror, an electronic target calibration mirror and the like, but all of the target calibration mirrors need a target to provide a calibration target.

[0003] In order to facilitate correction or due to environmental restrictions, target calibration is mostly carried out at a short distance, but the traditional short-distance target calibration only provides a designed target plate: a target plate without attitude correction, which has a low calibration accuracy and a large size due to the influence of the attitude of the target plate; and a target plate with attitude correction, which eliminates the influence of the attitude of the target plate.

[0004] For aiming equipment, the distance between the aiming axis and the firing axis is several tens of centimeters or even several meters, and through calculation, the target is basically not less than the distance, so the size of the target is relatively large, which seriously affects the portable use. SUMMARY

[0005] Therefore, the present application provides a miniaturized self-positioning target device, which reduces the size of the target and improves the calibration accuracy on the basis of a target plate that can correct the attitude.
