Abstract: A public transport vehicle charging system is applied to multiple charging stations and an electric vehicle. The public transport vehicle charging system includes a server communicatively connected to the charging stations and the electric vehicle. The server is configured to establish a charging decision model according to multiple historical conditions and a transport schedule. The server is configured to calculate multiple ideal decisions according to the historical conditions and the transport schedule, so as to adjust multiple parameters in the charging decision model. When the electric vehicle drives toward a first charging station according to the transport schedule, the server is configured to input a current condition into the charging decision model, so as to selectively charge the electric vehicle by the first charging station. The current condition includes a current remaining power and a current position of the electric vehicle.

Abstract: A system and method for creation of high density virtual content is provided, according to a preferred embodiment, a point is selected within a point cloud extracted from the original image; a radius set using a ratio of the distance between the selected point and the closest point thereto to the resolution of the original image is sequentially reset at predetermined intervals to create virtual content for each reset radius; and a section-wise optimal radius is derived from all the radii on the basis of the color image differences between each created virtual content and the original image for each section, thereby creating virtual content with the derived optimal radius for each section, whereby it is possible to implement a sense of reality for high density virtual content with a small number of samples.
