摘要

Aspects of the disclosure relate to adjusting a virtual camera's orientation when a vehicle is making a turn. One or more computing devices may receive the vehicle's original heading prior to making the turn and the vehicle's current heading. Based on the vehicle's original heading and the vehicle's current heading, the one or more computing devices may determine an angle of a turn the vehicle is performing and The one or more computing devices may determine a camera rotation angle and adjust the virtual camera's orientation relative to the vehicle to an updated orientation by rotating the virtual camera by the camera rotation angle and generate a video corresponding to the virtual camera's updated orientation. The video may be displayed on the display by the one or more computing devices.

說明書

The virtual camera system may continually adjust the camera rotation angle based on the angle of the turn the vehicle is currently performing relative to the heading the vehicle was traveling prior to entering the turn. In this regard, the virtual camera system may update the camera rotation angle in substantially real-time by continually calculating a camera rotation angle based on the angle of the turn. For instance, the vehicle may be travelling along a projected trajectory 901 at an initial heading 903 and the virtual camera 701 may be positioned in the default position with a first field of view 920.

As the vehicle 100 begins to turn, the heading of the vehicle may be updated to a new heading 1003, as shown in FIG. 10. The difference between the initial heading and the new heading may be input into the rotation table and a camera rotation angle may be output. The virtual camera system may then rotate the virtual camera 701 by the output camera rotation angle, thereby causing the field of view of the virtual camera 701 to also rotate by the camera rotation angle to show a second field of view 1020, as further shown in FIG. 10.
