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.

Upon the vehicle performing a turn, the fixed position virtual camera 501 may remain in the default position relative to the vehicle, such that the video will continue to provide the vehicle's surroundings 610 and the vehicle's projected trajectory 620 captured in the first heading 505 and located within the set field of view 503 as shown in the example video of FIG. 6.

As the vehicle performs a turn the position of the virtual camera may be rotated around the vehicle to present video within an adjusted field of view corresponding to the vehicle's anticipated heading. In this regard, the virtual camera may rotate a predetermined distance around the vehicle, from the default position, as the vehicle performs the turn. For example, upon the vehicle 100 making a turn in a first direction 710 from a first road to a second road, the virtual camera 701 may rotate counter clockwise from its fixed positioned to be directed at a new heading 705, as shown in FIG. 7. As such, the field of the view of the virtual camera may correspond to an updated field of view 703.

The updated field of view 703 may be adjusted such that the video includes imagery of the second road 812 onto which the vehicle 100 is turning, as shown in FIG. 8. Although the above example shows the vehicle 100 turning from a first road 811 to a second road, as discussed below, the virtual camera rotation may occur when the vehicle 100 makes any turning motions, such as around a bend on a road or into a parking spot.
