In traditional video surveillance, multiple sub-shots are tiled on the display in a 2D manner. It is difficult to correspond the sub-shot video to the actual geographical location, and it is impossible to conduct effective and intuitive real-time monitoring of large scenes, and there is no situational awareness. The HT Video Fusion solution fuses 2D images into a 3D model of the scene, providing operators with intuitive video images and simple view control.

The HT video fusion technology uses WebGL technology to process video images in real time using GPU high-performance computing capabilities. Image processing does not occupy CPU resources, and the entire solution has a smooth screen.

Electronic patrol system

The electronic patrol system is a means for managers to check whether the patroller arrives at the specified location according to the patrol route at the specified time. The traditional electronic patrol requires the patrol personnel to hold the patrol device and patrol along the specified route. Through the visualization system of Tupu software, each inspection point is integrated into the system, and the roaming electronic patrol system is displayed on a large screen. Tupu can seamlessly integrate various multimedia functions of HTML5, and display the monitoring situation of inspection points in real time, which is convenient for inspectors to view. with records.

When the patrol arrives at the corresponding patrol point, the corresponding real-time video display will appear. The operation and maintenance personnel can choose whether the scene is safe or unsafe. The confirmed patrol point will continue to roam the next patrol point. Check. Realize station safety patrol and scientific management patrol system. In addition, Tupu's smart station system can access relevant video images anytime and anywhere, and meet the monitoring needs of decision makers for real-time situational awareness and historical data retrospective of resource database retrieval, monitoring, and evaluation.
