Description

Technical Field

[0001] The present invention relates to the technical field of laser weapon testing, and in particular to a method and system for testing the aiming performance of a laser weapon. Background Art

[0002] Laser weapons are weapon systems that use high-energy beams generated by laser beams to attack and destroy targets. It is based on laser technology, uses lasers to convert electrical energy into laser beams, and achieves killing effects by focusing and irradiating targets. One of the characteristics of laser weapons is high energy density. The laser beam can release a large amount of energy to the target in a very short time, forming a high temperature and high pressure area, which can instantly melt, burn or destroy the target object. Due to the fast and highly concentrated energy transmission speed, laser weapons have a long range and high hit accuracy, and can cause great destructive power in a very short time. Laser weapons have high collimation and controllability. The propagation of laser beams has almost no deviation compared to ballistic weapons, allowing laser weapons to accurately aim at targets and carry out precise strikes. In addition, laser weapons also have the ability to adjust power and duration, and can carry out long-term continuous shooting or short-term pulse shooting when necessary to meet different tactical needs. Laser weapons also have a fast response speed. Since the transmission speed of the laser beam is close to the speed of light, laser weapons can quickly start and strike targets after receiving instructions, reducing the time window for target escape or reaction. This enables laser weapons to have excellent performance in areas such as air defense, anti-missile and anti-boat, and can track and destroy high-speed moving targets in real time.

It is based on laser technology, uses lasers to convert electrical energy into laser beams, and achieves killing effects by focusing and irradiating targets. One of the characteristics of laser weapons is high energy density.

[0066] In recent years, with the increasing complexity of international relations, the upgrading of military equipment in various countries is also in full swing. The application of laser weapons on the battlefield has become increasingly important. The aiming accuracy of laser weapons, especially the testing of laser weapons, has become an important criterion for the inspection of laser weapons. Most of the existing laser equipment tracking and aiming performance test equipment adopts laboratory conditions for testing, with low test accuracy and poor test results.

[0067] Reference Figure 1 The present invention provides a method for testing the aiming performance of a laser weapon, comprising the following steps:

[0068] Step 100, the original image on the target plate body 6 is collected by the image acquisition unit 5; the image acquisition unit can be a camera, a camera, a COMS component, a drone, etc. The original image on the target plate body 6 includes the beacon spot and the laser weapon spot for subsequent data processing.

[0069] Step 300, use the correction model to correct the original image to obtain a corrected image; by correcting the original image with the correction model, the perspective and distortion of the camera lens are overcome to obtain an accurate corrected image. The original image before correction is as follows: Figure 5 As shown, the corrected image is Figure 6 shown.

For example, the beacon spot parameters and the laser weapon spot parameters include the beacon spot center point and the laser weapon spot center point, respectively.

The aiming accuracy of the laser weapon can be determined based on the error value between the beacon spot center point and the laser weapon spot center point, and the tracking performance of the laser weapon can be obtained by processing multiple continuous images.

[0072] The laser weapon aiming performance testing method provided by the present invention acquires an image on a target plate body by an image acquisition unit, and uses a correction model to correct the image, thereby avoiding the problem of inaccurate beacon spot parameters and laser weapon spot parameters due to image distortion.

[0073] In one embodiment, step 200 is further included, generating a correction model according to a correction model generation strategy each time the relative position between the image acquisition unit 5 and the target plate body 6 changes.

[0074] The correction model is determined based on the relative position of the image acquisition unit 5 and the target plate body 6, so that an accurate corrected image can be obtained after the original image is corrected using the correction model. Since each change in the relative position of the image acquisition unit 5 and the target plate body 6 will bring about a change in the viewing angle of the image acquisition unit 5, the correction model needs to be regenerated after each position change.

[0075] The generation of the calibration model in step 200 specifically includes the following process:

[0076] Step 210, obtaining the size of the target plate body 6 and the size of the correction image, wherein the size of the correction image is a preset value and can be expressed in pixels, for example, 1240*800;

[0077] Step 220, obtaining a scale parameter of the coordinate model according to the size of the target plate body 6 and the size of the correction image, wherein the scale parameter is a ratio value of the size of the target plate body 6 and the size of the correction image;

[0078] Step 230, lighting up the multiple LED light sources 9 on the target plate body 6;

[0082] In this embodiment, multiple LED light sources 9 on the target plate body 6 are used as calibration points for easy identification during image calibration. First, a coordinate formula is obtained based on the size of the plate body 6 and the size of the calibration image. Then, theoretical coordinates are obtained through the coordinate formula based on multiple LED light sources. Based on the theoretical coordinates and the coordinates of the image before calibration, the parameters of the calibration model are obtained to determine the calibration model. Finally, the image is calibrated based on the calibration model, avoiding the deviation in identifying the beacon spot and the laser weapon spot, and further causing the problem of inaccurate testing.

[0083] In one embodiment, the preset model in step 260 is:

[0084] ;

[0085] ;

[0086] Among them, x represents the coordinate of the original image in the x direction, and y represents the coordinate of the original image in the y direction. Represents the corrected image The coordinates in the direction, Represents the corrected image The coordinates in the direction, It is a parameter obtained according to the theoretical positions of the multiple LED light sources 9 and the positions of the multiple LED light sources 9 in the original image.

Represents the corrected image The coordinate value in the direction, Represents the corrected image The coordinate value in the direction, and It is a proportional parameter obtained according to the size of the target plate body 6 and the size of the correction image.

[0091] Since the coordinates of the corrected image can be directly expressed by pixel positions, When , you can directly use the maximum number of pixels of the horizontal and vertical coordinates, such as a 1240*800 image. is 1240, is 800.

[0092] In one embodiment, correcting the original image using the correction model in step 300 includes:

[0093] The positions of multiple light sources are respectively identified in the original image; for example, the position of the light source can be identified by identifying the grayscale information of the image, which can be implemented by using a neural network model.

[0094] Calculating the correction positions of the plurality of light sources respectively based on the correction model;

[0095] The multiple light sources in the original image are adjusted to the correction positions respectively to drive the adjustment of the original image as a whole to obtain the correction image. For example, the upper left light source position is stretched upward and the lower left light source position is stretched downward, so that the entire image is stretched in the upward and downward directions.

[0096] In one embodiment, calculating the beacon spot parameters and the laser weapon spot parameters based on the correction image in step 400 includes:

[0097] Step 410, preprocessing the corrected image; for example, the preprocessing may include using a 3×3 mean filter algorithm to perform denoising.

[0098] Step 420: Supplement the integrity of the light spot area in the image based on the bilinear interpolation method.

[0099] Step 430, obtaining the center of gravity position of the light spot based on the center of gravity method.

[0100] Step 440, dividing the light spot into beacon light spot parameters and laser weapon light spot based on color, for example, the beacon light spot is green and the laser light spot is red.

[0101] In one embodiment, the center of gravity of the light spot in step 430 is :

[0102]

[0103]

[0104] Among them, I(x,y) represents the gray value of the pixel with coordinates (x,y). is the horizontal coordinate of the pixel at the center of the light spot, is the vertical coordinate of the pixel in the center of the light spot. x is the horizontal coordinate of each pixel in the light spot, and y is the vertical coordinate of each pixel in the light spot.

[0105] In one embodiment, before the image acquisition unit 5 acquires the image on the target plate body 6 in step 100, the process further includes:

[0106] Step 010 , adjusting the angle of the target plate body 6 based on the image observed by the sight 10 , so that the target plate body 6 is perpendicular to the laser emission direction of the laser weapon 4 .
