Abstract
Systems and methods may calibrate an indicator of speed of an autonomous vehicle. In one implementation, a system may include at least one processor programmed to: receive from a camera at least a plurality of images representative of an environment of the vehicle; analyze the plurality of images to identify at least two recognized landmarks; determine, based on known locations of the two recognized landmarks, a value indicative of a distance between the at least two recognized landmarks; determine, based on an output of at least one sensor associated with the autonomous vehicle, a measured distance between the at least two landmarks; determine a correction factor for the at least one sensor based on a comparison of the value indicative of the distance between the at least to recognized landmarks and the measured distance between the at least two landmarks.

35. A system for calibrating an indicator of speed of an autonomous vehicle, the system comprising:
at least one processor programmed to; determine a distance along a road segment based on an output of at least one sensor associated with the autonomous vehicle; receive, via a wireless transceiver, a distance value associated with the road segment; and determine a correction factor for the at least one sensor based on the determined distance along the road segment and the distance value received via the wireless transceiver. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42)
