specific Embodiment approach 1

[0032] Specific implementation mode one: the following combination image 3 This embodiment is described. This embodiment includes a visual tracking system, a photoelectric conversion circuit, an amplifier circuit, a single-chip microcomputer, and a quadcopter.

[0033] The visual tracking system is composed of a single camera, the output end of the camera 1 is connected with the photoelectric conversion circuit 2; the input end of the photoelectric conversion circuit 2 is connected with the camera 1, and the output end is connected with the amplifier circuit 3; the input end of the amplifier circuit 3 is connected with the photoelectric conversion circuit 2, the output end is connected with the single-chip microcomputer 4; the input end of the single-chip microcomputer 4 is connected with the amplifier circuit 3, and the output end is connected with the interface 6;

[0034] The single-chip microcomputer processes the information transmitted by the visual tracking system, com...

specific Embodiment approach 2

[0040] Specific embodiment two: the difference between this embodiment and embodiment one is that it also includes a filter 5, and a particle filter algorithm is added in the single-chip microcomputer 4, the input end of the filter 5 is connected with the single-chip microcomputer 4, and the filter 5 The output end is connected with the single-chip microcomputer 4.

[0041]Due to the unclear image quality collected by the camera, there is a deviation in the calculation of the shooting range of the multi-barrel rocket, so a particle filter is added to filter the image error, and the processed information is transmitted to the single-chip microcomputer, and the single-chip microcomputer processes the filtered Information is processed to reduce random errors and improve shooting accuracy.

Description

technical field [0001] The invention belongs to the research field of shooting accuracy and shooting range measurement of multiple rockets, and in particular relates to a shooting accuracy measurement of multiple rockets with a filter installed on a four-axis aircraft, which can measure the shooting range of multiple rockets and calculate the shooting accuracy. instrument. Background technique [0002] Due to the complex and changeable position of the shooting target of multiple rockets, such as the presence of obstructions, the traditional measuring instrument has a dead angle of observation, and in some cases it cannot achieve the purpose of measuring the shooting range of multiple rockets or the obtained multiple The shooting range of the rocket is not accurate, which leads to a large error in the calculation of the shooting accuracy; and the traditional multi-tube rocket shooting accuracy measuring instrument needs to adjust the angle of the camera, and the visual images...
