Description

Technical Field

[0001] The present invention relates to the technical field of 3D modeling, and in particular to a virtual visualization 3D modeling method based on walled area video monitoring. Background Art

[0002] 3D modeling is a technology that uses professional software to create three-dimensional models, which converts real-world objects or fictional objects into data forms that computers can understand and process. This technology is widely used in movies, games, architecture, engineering, and manufacturing, creating many amazing visual effects and innovative designs.

[0003] The basic process of 3D modeling includes three main steps: modeling, texturing, and rendering. Modeling is the process of converting the shape, size, and structure of an object or scene into a 3D model. Designers use tools and techniques in modeling software to shape and define the appearance and shape of the object. Texturing is the process of adding surface details and colors to the model. By creating and editing material maps using texturing software or drawing software, you can add realism and details to the model. Rendering is the process of adding lighting, shadows, and other special effects to the model to make it look realistic on the computer screen. By adjusting parameters such as the position, intensity, and color of the light source, you can create amazing visual effects.

[0004] When performing 3D visualization modeling of the fence monitoring area, the existing modeling methods are prone to leaving blind spots and are unable to fully display the scenes of the fence monitoring area. Summary of the invention

[0005] 1. Technical Problems Solved

[0006] The technical problem to be solved by the present invention is that the existing 3D modeling method of the wall monitoring area cannot fully display the scene of the wall monitoring area.

[0007] 2. Technical Solution

[0008] In order to solve the above technical problems, a virtual visualization 3D modeling method based on video surveillance of a walled area is provided, comprising the following steps:

[0009] S1. 3D scene modeling: constructing a 3D scene model of the walled area through artificial modeling, establishing a digital surface model, describing the real texture information through actual photo mapping, and realizing the 3D model construction of the walled area;

[0010] S2. Video surveillance equipment layout: In the three-dimensional scene model, the monitoring target is determined according to the requirements of the security monitoring area, and the detection area corresponding to the monitoring target is generated. By analyzing the requirements of the detection area for the video surveillance coverage effect, the equipment layout plan of the video surveillance system is formulated;

[0011] S3, PSIM software application, in the field of video surveillance, the use of 3D models can improve security warning capabilities, using satellite images and CAD drawings to draw the plane structure into the 3D model;

[0012] S4. Enhanced visual monitoring management: 3D technology can maximize safety warnings. By installing a set of simulation maps inside the monitoring system and combining it with a high-definition monitoring system to determine whether target movement needs to trigger an alarm, visual monitoring management can be enhanced.

[0013] S5. Post-processing and detail optimization. When making a three-dimensional scene, pay attention to the processing of details and the use of lighting to improve the accuracy and visual impact of the model.

[0014] Furthermore, when performing manual modeling in S1, CAD drawings, on-site measurement data and current status photos are used as a basis.

[0015] Furthermore, when formulating the equipment layout plan of the video surveillance system in S2, camera components are placed in the three-dimensional scene model to simulate the layout of multiple video surveillance devices to ensure that the coverage effect of the surveillance equipment meets the requirements.

[0016] Furthermore, when establishing the 3D model in S3, the 3D model is created by using a layered method.

[0017] Furthermore, the 3D technology in the S4 and the PSIM service provide an enhanced integrated safety model, providing better situational awareness capabilities.

[0018] Furthermore, the use of lighting in the S5 is flexibly adjusted according to the needs of the scene to create a suitable atmosphere and visual effects.

[0029] S1. 3D scene modeling. First, it is necessary to build a 3D scene model of the walled area. This is usually achieved through manual modeling. Using CAD drawings, on-site measurement data and current photos as the basis, a digital surface model is established. The real texture information is described through actual photo mapping to achieve the construction of a 3D model of the walled area.

[0030] S2. Video surveillance equipment layout: In the 3D scene model, the surveillance target is determined according to the requirements of the security surveillance area, and the detection area corresponding to the surveillance target is generated.
