[0009] Aiming at the characteristics that binary sensors are limited by the number and placement of sensors and modulating elements in the field of view, the present invention proposes a visualization method for the deployment of sensors and modulating elements and space division for monitoring area division, which fully considers the position of sensors There are many combinations of modulation components and field of view. Taking into account the difficulty of measuring the location information of the actual deployment segmentation area, the high cost of personnel and time, it can ensure that the monitoring area segmentation and coding information that needs to be measured can be obtained through simulation experiments, so as to modulate the sensor and field of view. The deployment quantity and location of components are optimized, and the segmentation effect and coding of the monitoring area are displayed in a visual display, so that it is convenient for deployment personnel to evaluate and adjust the deployment scheme of sensors and modulation components

Embodiment Construction
[0064] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0065] The sensor in this embodiment is an infrared sensor. Since the sub-regions of each sensor divided by infrared rays cannot be seen under visible light, and it is necessary to use a field of view modulation element to further divide the field of view of each sensor, the present invention proposes a method for Visualization method for sensor and modulating element deployment for monitoring area division. Such as figure 1 As shown, the method steps include six steps: deployment scheme setting, data preprocessing, spatial segmentation information extraction, deployment parameter analysis, deployment scheme adjustment, and visual display.

The invention relates to a sensor and modulation element deployment visualization method for monitoring area division. The method comprises the step of simulating a generated sensor vision field segmentation effect and a coding result of each monitoring area according to the number and the positions of the set sensors and the sensor vision field modulation elements, Wherein the segmentation effect comprises the shape and the size of the segmented vision field and each vertex position of a polygon formed by the vision field. Optimized positions of the sensor and the modulation element can be quickly known through simulation visualization. The method has the advantages of being high in visualization, comprehensive in deployment parameter information, convenient to use and high in operation efficiency, and deployment personnel can be helped to rapidly and conveniently adjust the deployment scheme and display the visual deployment effect. The method is an efficient visualization method which is wide in applicability and can be applied to large-scale sensor deployment.
