Abstract
Aspects of the disclosure relate to verifying the location of an object of a particular type. For instance, a plurality of images of an environment of the vehicle may be received. Associated objects of the particular type may be identified in ones of the plurality of images. A plurality of estimated locations may be determined for the object using a plurality of different localization techniques. For each image of the ones of the plurality of images, determine a reprojection error for each of the plurality of estimated locations. For each of the plurality of estimated locations, an error score is determined based on the reprojection errors. An estimated location may be selected from the plurality of estimated locations based on the determined error score. This selected location may be used to control a vehicle in an autonomous driving mode.
