[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] To facilitate understanding of this embodiment, the embodiment of the present invention is described in detail below.

[0047] Embodiment 1:

[0048] Figure 1 This is a flow chart of the application method of the floodlight intelligent camera light spot boundary sense provided in the first embodiment of the present invention.

[0049] Reference Figure 1 , the method comprises the following steps:

[0050] Step S101, determining the attribute information of the light spot, the attribute information includes the shape of the light spot, the irradiation distance of the light spot and the size of the light spot;

[0051] Here, the shape of the required light spot (such as round, square, etc.), the irradiation distance and the size of the light spot (such as radius, side length, etc.) are determined according to the actual monitoring requirements. The attribute information of the light spot is not limited to the above information, and may also include other information.

[0052] Step S102, obtaining a lens group, where the lens group includes at least one lens;

[0053] Step S103, taking the light spot boundary sense as the target condition, optimizing and calculating the parameter information of the lens through optical software to obtain various parameter values ​​of the lens under the required light spot condition;

[0054] Step S104, adjusting various parameter values ​​of the lens according to the shape of the light spot until the light spot reaches the required specification.

[0055] Specifically, the lens group includes at least one lens, and the types of lenses include spherical, aspherical and free-form surfaces. The adjustable parameter information of the lens includes outer diameter, curvature radius, thickness, position and surface shape, but is not limited to the above parameters, and may also include other parameters.

[0056] By optimizing these parameters, the size and shape of the light spot can be controlled. For example, changes in the curvature of the lens will affect the size of the light spot, and different curvature combinations can produce light spots of different sizes and shapes. Figure 3-Figure 5 shown.

[0057] Schematic diagram of the effect of lens curvature on light spot size: intuitively shows how changes in lens curvature affect the size of the light spot on the screen, and helps explain the principle of lens parameter control in the optical solution.

[0058] Further, step S103 includes the following steps:

[0059] Step S201, setting the parameter information of the lens as a variable, and selecting an optimization function in the optical software;

[0060] Step S202, setting the light spot boundary sense as the actual required illumination value, and using the optimization function to optimize the variables to obtain the various parameter values ​​of the lens under the required light spot condition.

[0061] Furthermore, the spot boundary sense is achieved in the following manner, referring to formula (1):

[0062] D=Z 0.6h -Z 0.1h ≤0.2m (1)

[0063] Among them, Z 0.1h is the position coordinate of the first illumination point, Z 0.6his the position coordinate of the second illumination point, D is the distance between the second illumination point and the first illumination point, and h is the maximum illumination of the light spot.

[0064] Specifically, refer to Figure 2 Schematic diagram of the curve showing the change of spot illumination with position. Figure 2 The relationship between the spot illumination and the position coordinates is shown, that is, the positions of the 60% maximum illumination point and the 10% maximum illumination point and the calculation method of the distance D between them.

[0065] Furthermore, when the light spot reaches the required specifications, the method further includes the following steps:

[0066] Step S301, manufacturing and processing the lens according to the adjusted parameter values, and installing it behind the light source of the pan-tilt smart camera, so as to construct a complete lighting system.

[0067] Furthermore, after the pan-tilt smart camera is installed, the method further includes the following steps:

[0068] Step S401, when measuring in a dark room, the ambient illumination is lower than 0.01 lx;

[0069] Step S402, setting a plurality of equidistant position points from the center to the edge of the light spot on the detection plane;

[0070] Step S403, measuring the illumination value of each position point;

[0071] Step S404, generating a plane illumination distribution curve according to the illumination value of each position point;

[0072] Step S405 , comparing the illumination value of each position point with the edge sense of the light spot, so as to determine whether the edge clarity of the light spot meets the standard.

[0073] Here, the installed pan-tilt smart camera is tested to check whether the light spot effect meets expectations under different environmental conditions, such as light spot shape, boundary clarity, light and dark contrast, etc. If necessary, the lens parameters can be fine-tuned to achieve the best monitoring lighting effect.

[0074] In one embodiment, the requirement is to achieve a circular spot with a radius of 1.6m at an illumination distance of 5m, and the lens group uses a single aspherical lens. After optimization by optical software, the specific parameters of the optical lens are shown in Table 1:

[0075] Material outer diameter thickness Location Radius of curvature Resin 10mm 4.56mm 2.02mm R1:7.06, R2:5.13

[0076] The final light spot effect is as follows Figure 6 As shown, the definition of the light spot boundary sense is met. Figure 6The final light spot effect achieved under specific parameters was demonstrated, verifying that the optical solution can meet the definition of a clear sense of boundary of the light spot and achieve the expected lighting effect.

[0077] In this application, through the obvious sense of light spot boundaries and light-dark contrast effects, users can more easily identify objects and human activities in the monitoring area, especially at night or in low-light environments, and can quickly detect potential intruders.

[0078] The requirements of different irradiation distances and spot shapes can be met by optimizing the lens group parameters, thus improving the flexibility and adaptability of smart camera lighting.

[0079] It improves the overall security monitoring experience and provides more reliable protection for home security.
