Claim 0:
1. A camera vision method for an autonomous driving vehicle, the method comprising:
receiving a series of road images from a side-view camera sensor of the autonomous driving vehicle, wherein each image in the series of road images is taken at a different time,
wherein a larger quantity of the series of road images is analyzed to determine directions of travel and speeds of distant objects compared to the series of road images that are analyzed to determine directions of travel and speeds of objects that are close to the autonomous driving vehicle;

generating, for each object from objects captured in the series of road images, a series of bounding boxes in the series of road images, wherein each bounding box corresponds to an image in the series of road images;
determining, for each object from the objects, a direction of travel or that the object is stationary;
determining a speed of each object for which the direction of travel has been determined;
determining, based on the directions of travel, speeds, or stationarity of the objects, whether the autonomous driving vehicle can safely move in a predetermined direction,
wherein a quantity of the series of road images that are analyzed before the determining whether the autonomous driving vehicle can safely move in the predetermined direction depends on a noise level of the directions of travel, speeds, or stationarity of the objects; and

sending one or more control signals to the autonomous driving vehicle to cause the autonomous driving vehicle to move or to remain stationary based on the determining whether the autonomous driving vehicle can safely move in the predetermined direction.
