Mixed reality view for enhancing pedestrian safety
Methods, apparatuses, and computer-readable media are disclosed for providing a mixed-reality scene. In response to a pedestrian detection event at a first vehicle, a sequence of mixed-reality images is presented to a driver of a second vehicle. At least one image in the sequence of mixed-reality images results from merging (a) an image captured by a camera aboard the first vehicle and (b) an image captured by a camera aboard the second vehicle. The merging may comprise de-emphasizing an occluded portion of the image captured by the camera aboard the second vehicle and emphasizing an unoccluded portion of the image captured by the camera aboard the first vehicle. The unoccluded portion of the image captured by the camera aboard the first vehicle may provide, in the merged image, visibility of a pedestrian at least partially blocked from a view of the driver of the second vehicle.
