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

To minimize minor camera rotations, such as those caused by minor oversteering corrections, and to smooth larger camera rotations, the virtual camera system may use a squashing function. For instance, the angle of the turn the vehicle is performing may be input into the squashing function and a camera angle rotation value, which is the same, or more gradual than the angles of the turn, may be output.

At unprotected turns, the virtual camera system may rotate the virtual camera to generate imagery corresponding to oncoming traffic at unprotected turns. For instance, the virtual camera may rotate in the opposite direction of the vehicle's projected trajectory to generate imagery corresponding to other vehicles travelling on the road where the vehicle is attempting to turn.

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 the virtual camera may be positioned above the vehicle and the pitch of the virtual camera may be adjusted such that it looks straight down to the vehicle. The virtual camera may then generate a video which includes imagery of the vehicle's surroundings on all sides of the vehicle.
