Abstract
An approach is provided for determining quality assessment of cross view feature correspondence using bundle adjustment techniques. The approach, for example, involves retrieving a plurality of annotated images that are labeled with one or more feature correspondence labels. The approach also involves performing a bundle adjustment process on the plurality of annotated images to compute a three-dimensional (3D) location and a residual error of a feature corresponding to the one or more feature correspondence labels. The approach further involves flagging the one or more feature correspondence labels as potentially incorrect based on determining that the residual error is greater than an error threshold.
