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

As one example, the virtual camera system may rotate the virtual camera to generate imagery corresponding to oncoming traffic at unprotected turns. In this regard, the virtual camera may rotate in the opposite direction of the vehicle's projected trajectory 1430 to generate imagery corresponding to other vehicles 1501 travelling on the road where the vehicle is attempting to turn 1420, as shown in FIGS. 14 and 15. The camera rotation angle may be predetermined for unprotected turns, such as 45° or more or less. As such, the generated video may provide passengers of the vehicle with imagery similar to that which they would experience were they driving the vehicle. Unprotected turns may include turns where the vehicle is turning onto a road where traffic is moving, such as a right on red or right at a stop sign at an intersection where the road the car is turning onto does not require other vehicles to stop at the intersection.

The height and pitch of the virtual camera may also be adjusted to capture more or less of the vehicle's surroundings. For example, when the vehicle is stopped at an intersection 1600 the virtual camera 710 may be positioned above the vehicle 100 and the pitch of the virtual camera may be adjusted such that it looks down to the vehicle, as shown in FIG. 16. The virtual camera 710 may look straight down on the vehicle 100. The virtual camera 710 may then generate a video which includes imagery from all around the vehicle as further shown in FIG. 16.
