[0031] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0032] The present application provides a laser ground target radiation danger area prediction method, which is applied in the scene of laser target shooting. In this scene, the laser emission point is located in the high altitude, the target point is located on the ground, and the ground target point is shot from the high altitude. The method predicts the area that may pose a threat to human safety under the action of the thermal effect of the laser, the reflection and scattering of the laser on the ground, and the like.
[0033] The method comprises the following steps:
[0034] Step 101, determining the spatial positions of a laser emission point and a target point, acquiring laser parameters and test area environment parameters, and target arrangement parameters;
[0035] Step 102, acquiring laser target point power according to the spatial positions corresponding to the laser emission point and the target point, the laser parameters, and the environment parameters;
[0036] Step 103, acquiring a light beam radiation radius according to the laser target point power;
[0037] Step 104, according to the distance between the laser target point and the target surface reflective light absorbing material, the target area radius is obtained; wherein the distance between the laser target point and the target surface reflective light absorbing material is the target distribution parameter;
[0038] Step 105, according to the beam radiation radius and the target area radius, the laser radiation danger area radius is obtained.
[0039] As shown in the overall flow chart of the method. Figure 1
[0040] In one embodiment, the spatial position in step 101 is a three-dimensional spatial position, which can be a position represented by (x, y, z) in a spatial coordinate system with the earth as the center, or a relative spatial position obtained by taking a certain object as the reference object, such as a target point. The spatial position can be obtained by field measurement. The laser parameters such as laser power can be obtained by measuring equipment (such as a laser power meter), querying product manuals, etc. The environmental parameters of the test area include parameters affecting the propagation of laser energy, the condition of the ground, etc.
[0041] In one embodiment, the laser parameters include incident light power; the environmental parameters include visibility and geographical area constant. Step 102 includes: determining the height of the laser emission point from the ground according to the spatial position of the laser emission point, and determining the horizontal straight line distance between the emission point and the target point according to the spatial positions of the laser emission point and the target point; according to the height of the laser emission point from the ground, the horizontal straight line distance between the emission point and the target point, the incident light power, the visibility and the geographical area constant, the laser target point power is obtained.
[0042] Specifically, the laser target point power P o The calculation formula is as follows:
[0043]
[0044] Wherein, l represents the horizontal straight line distance between the laser emission point and the target point; h represents the height of the laser emission point from the ground; P in represents the incident light power; V represents the visibility of the test area; K represents the geographical area constant of the test area, which includes desert, rural area, urban area and marine scene, and the corresponding desert corresponds to K value of 2.496, the rural area corresponds to K value of 2.828, the urban area corresponds to K value of 3.132, and the marine corresponds to K value of 4.543.
[0045] In one embodiment, step 103 includes: determining the maximum allowable laser radiation exposure; according to the laser target point power, and taking the maximum allowable laser radiation exposure as the limit, the beam radiation area radius is obtained.
[0046] Wherein, the maximum permissible exposure (MPE, Maximum Permissible Exposure) includes the maximum permissible exposure of laser radiation to the human eye and the maximum permissible exposure of laser radiation to the skin, which refers to the maximum exposure level without damage to the eye or skin after exposure or after a long time. This data can be set by itself, or can be determined according to national or industry standards, such as GB7247.1-20142 specifies that the maximum permissible exposure of laser radiation to the human eye is 5.1*10 2 J / m 2 .
[0047] If the maximum permissible exposure of laser radiation to the human eye is used as a limit, the critical value of the beam radiation zone radius of the laser target area is determined, which is lower than the maximum permissible exposure of laser radiation. At this time, the beam radiation zone radius R w The formula is expressed as:
[0048]
[0049] Wherein, P o is the power of the laser target point; 170 is the value of the maximum permissible exposure of laser radiation to the human eye 5.1*10 2 Divided by 3, which simplifies the algorithm here.
[0050] In one embodiment, the target arrangement parameters include the distance between the laser target point and the target surface reflective light absorbing material. In step 104, the laser hits the target point of the laser target, and is reflected on the target surface reflective light absorbing material after the laser target. According to the distance between the laser target point and the target surface reflective light absorbing material, the target area radius is obtained.
[0051] As shown in Figure 2 , it is a schematic diagram of the laser target area.
[0052] In one embodiment, step 105 includes: according to the beam radiation radius and the target area radius, the laser radiation danger area radius is obtained.
[0053] Specifically, the formula of the laser radiation zone danger area radius R o is expressed as:
[0054] Ro=3(R zhi +R w )
[0055] Wherein, R w represents the beam radiation zone radius, and R zhi represents the target area radius.
