Embodiment Construction

[0047] In order to better illustrate the purpose and advantages of the present invention, it will be further described below in conjunction with the accompanying drawings and live ammunition shooting accuracy test examples.

[0048] The live ammunition shooting accuracy test method of the artillery based on the high-speed camera of the present invention is: by adopting an area array camera and two high-speed line array cameras, placing them on a straight line, the calibration target surface is calibrated to obtain the calibration point data and Real-time detection of the image of the shell passing through, while the embedded image processing system processes the image collected by the high-speed line array camera and records the time when the shell passes through the two high-speed line array cameras, once the shell passes through the second high-speed line array camera is detected Immediately send a trigger signal to the area array camera to collect the image when the shell pa...

Abstract

The invention relates to a high-speed camera-based test method and device for live ammunition shooting accuracy of artillery, belonging to the field of artillery test and test. The test method provided by the present invention has high test accuracy; the test device does not need a real target, and the operation is simple. A high-speed line array camera is used to detect in real time whether there is a shell passing through, and the area array camera is triggered to expose and collect the image of the shell in μs level time to obtain the shell penetration. Through the position information of the virtual target surface, it can avoid the situation where multiple shells overlap or miss the target, and the wireless network is used for real-time data transmission. The real-time performance is good and the safety is completely guaranteed.

Description

technical field [0001] The invention relates to a high-speed camera-based method and device for testing the shooting accuracy of artillery live ammunition, belonging to the field of artillery testing. Background technique [0002] Artillery is one of the most widely used, most equipped, and highly lethal conventional weapons. The shooting accuracy of the artillery is the most important technical index to reflect the performance of the artillery, so it is very critical and essential to test the live ammunition shooting accuracy of the artillery. [0003] The accuracy and dispersion of artillery live ammunition shooting are the key technical indicators to measure the final performance of artillery. The existing real target testing methods mainly have the following inevitable problems: [0004] (1) It cannot be distinguished whether the shells overlap the target or miss the target. Since the existing real target test method calculates various technical indicators by manually ...
