The security monitoring EasyCVR video convergence comprehensive management platform has powerful data access, processing and distribution capabilities. The platform can provide video surveillance live broadcast, cloud recording, cloud storage, video retrieval and review, alarm reporting and query, platform cascading, PTZ Control, voice intercom, electronic map, trajectory tracking, H.265 automatic transcoding and other video capabilities.
In the electronic map module of the video surveillance management platform TSINGSEE Qingxi Video EasyCVR, when the channel device is set with latitude and longitude information, the location of the device can be seen on the electronic map, as shown in the following figure:
When we tested the function, we found that the coordinates of the device positioning were not accurate, and there was a serious offset, as shown in the following figure:
The latitude and longitude set by the device is in the circle in the lower left corner, but it is offset to the upper right corner on the map. After checking the code, I found that the coordinate conversion was added in the code, and the latitude and longitude were used as the coordinate points of the Tencent map to be converted into the Baidu map, but the actual data used was the coordinate point of the Baidu map.
Optimize the code and solve the offset problem.
The electronic map function of the security monitoring EasyCVR video convergence platform can display the front-end connected devices (cameras, vehicle monitoring, mobile soldiers, law enforcement devices, etc.) Real-time video monitoring can also support the drawing of historical driving trajectories, playback of historical trajectories, etc.
TSINGSEE Qingxi Video Surveillance Management Platform EasyCVR can gather, integrate and centrally manage all kinds of scattered video resources in a complex network environment, and realize authentication management, on-demand access, network-wide distribution and intelligent video resource management. Analysis, etc. The platform is highly integrated, highly open, and easy to deploy. It has broad application prospects in scenarios such as smart construction sites, smart parks, smart factories, smart docks, and smart water conservancy. Interested users can go to the demonstration platform for experience or deployment testing.
