After the intelligent monitoring hardware system is deployed, a three-dimensional visual monitoring system can be generated for intelligent monitoring.
And 2, generating a community three-dimensional live-action model according to the community plane graph.
Three-dimensional modeling software such as 3Ds Max, Maya, Rhino, Sketchup, Blender, AutoCAD and the like is used for manufacturing a highly reduced community three-dimensional live-action model.
And 3, generating a three-dimensional visual monitoring system for three-dimensional visual display in the WEB according to the community three-dimensional real scene model based on the WEBGL technology.
After a community three-dimensional live-action model is generated, universal three-dimensional data formats such as OBJ, FBX, 3DS and the like are output, then the three-dimensional data are converted into a format which is friendly to WEB environment, supports high expandability, multiple image layers and LOD and follows RESTAPI specification, such as GLTF, S3M, I3S, 3DTILES and 3DML, by combining a GIS technology, and finally, three-dimensional visual display is carried out by using a WEBGL technology. Such as loading a 3DTILES model using the cesum. cesum 3dtileset interface provided by cesium mjs.
And 4, step 4: the method comprises the steps of constructing a monitoring device model for monitoring devices deployed in a community, adding the monitoring device model into a three-dimensional visual monitoring system according to monitoring device deployment information, and enabling the three-dimensional visual monitoring system to obtain monitoring flows of the monitoring devices deployed in the community.
Different monitoring equipment models can be manufactured for the intelligent monitoring equipment according to the classified use of the monitoring equipment.
And (3) after the three-dimensional visual monitoring system is generated, according to the monitoring position deployment information on the CAD drawing drawn in the step 1, visually displaying the monitoring equipment model at the specified position in the three-dimensional visual monitoring system.
According to the monitoring equipment deployment CAD drawing, coordinate projection definition and conversion are carried out in GIS software (such as ArcGIS, Supermap, MapInfo and the like), after data correction, point location coordinate information of the monitoring equipment is extracted, such as (114.38764, 30.2456), and the monitoring equipment MODEL manufactured in the step 2 is combined, such as the monitoring equipment MODEL is visually displayed at a specified POSITION in a three-dimensional visualization system through specifying a coordinate point POSITION attribute and a path address MODEL attribute of a MODEL file by using a center.
After the monitoring equipment model is added to the three-dimensional visual monitoring system, communication can be carried out between the three-dimensional visual monitoring system and the hardware monitoring equipment, and monitoring flows of monitoring equipment deployed in a community can be obtained. The monitoring stream can be a video stream collected by a camera, and can also be a signal stream collected by other equipment such as RIFD electronic fence equipment.

And 4, integrating WEBGL development technology, customizing the interaction event of each monitoring device, expanding and displaying the basic information of the monitoring device, playing the video of the monitoring device and the like.
As WEBGL three-dimensional visualization, a user may interact with a model in the visualization through an external device such as a MOUSE, a touch pad, a stylus, and the like, for example, a MOUSE CLICK event, a MOUSE movement event, a MOUSE entry event, a MOUSE exit event, and the like, and for example, the user interaction may be enriched by means of a LEFT _ clip, a LEFT _ dot _ clip, and a motion _ MOVE event defined by a screenspace eventtype interface provided by a three-dimensional visualization library cesimjs. Therefore, the user can be allowed to browse the monitoring video, call the historical video and the like in real time through mouse interaction with the monitoring equipment model.
As another link of interaction, standard HTML tags can be used to display basic information of the monitoring device, such as: device name, device ID, device type, location of the device, device status, device photo, etc. Therefore, the basic information such as the serial number, the position, the state and the like of the monitoring equipment can be displayed in real time, and the monitoring equipment is convenient to manage.
Of course, the monitoring device video may also be played, for example, taking haikang as an example, the RTSP video stream of the haikang camera may be transcoded into an RTMP stream in real time, and then the video display and playing control may be performed by using HTML plug-ins such as VEDIOJS and the like in combination with the VEDIO tag provided by HTML 5.
In one embodiment, the three-dimensional GIS intelligent monitoring method further supports an automatic inspection function, and comprises the following steps:
step 6: and drawing an automatic routing inspection route in the three-dimensional visual monitoring system, and setting monitoring equipment to be called for the automatic routing inspection route.
In a three-dimensional visual scene, an automatic routing inspection route is compiled and drawn according to reference information such as a road network and the like, and the route is intelligently identified and tracked by a system when the automatic routing inspection is carried out.
When the device is arranged in automatic inspection, equipment needing to call monitoring video information can be specified according to the equipment identification number, the equipment position and the equipment type.
The drawn multiple automatic routing inspection routes can be saved and managed based on application scene requirements. For example, a plurality of automatic routing inspection routes can be drawn and stored, and each automatic routing inspection route is named, so that management is facilitated. It is also possible to set the effective time of each automatic patrol route, for example 6: 00-22: 00 execution route a, 22: 00-6: 00 execute route B, etc.
And 7: and starting automatic inspection in the three-dimensional visual system, automatically calling the monitoring equipment to be called set by the automatic inspection route, and playing the corresponding monitoring stream.
In one embodiment, the three-dimensional GIS intelligent monitoring method further supports automatic abnormal function analysis, and comprises the following steps:
and step 9: and if the called monitoring flow of the monitoring equipment has abnormity, recording abnormal information and reporting.
The three-dimensional visual scene starts automatic inspection according to a self-defined inspection route, when equipment needing to be taken monitoring video is met, inspection is automatically suspended, video information of the monitoring equipment is automatically taken, the monitoring equipment is opened, the monitoring video is played, after the intelligent equipment is automatically analyzed and judged, the inspection point is confirmed to be abnormal, the monitoring equipment is closed to continue inspection, if the abnormality is found, the abnormality is automatically recorded, the abnormality is reported, and finally the equipment is closed to continue inspection until the inspection is finished.
In the automated analysis study, we describe two small scenarios. For example, in the inspection process, a certain suspected illegal person is snapshotted and matched by a face recognition camera. Of course, photo samples of suspected law enforcement personnel have been entered into the system in advance. For example, the high-altitude parabolic camera detects that a person in a certain high-rise throws down a garbage bag.
Step 10: after the inspection is finished, the inspection result can be reported in a statistical manner.
And after the inspection is finished, automatically processing, storing and reporting the inspection result, and informing related personnel to process events.
