Abstract:
Techniques for generating maps without shadows are discussed herein. A plurality of images can be captured by a vehicle traversing an environment representing various perspectives and/or lighting conditions in the environment. A shadow within an image can be identified by a machine learning algorithm trained to detect shadows in images and/or by projecting the image onto a three-dimensional (3D) map of the environment and identifying candidate shadow regions based on the geometry of the 3D map and the location of the light source. Shadows can be removed or minimized by utilizing blending or duplicating techniques. Color information and reflectance information can be added to the 3D map to generate a textured 3D map. A textured 3D map without shadows can be used to simulate the environment under different lighting conditions.

Claim (Index 16):
A non-transitory computer-readable medium storing instructions that, when executed, cause one or more processors to perform operations comprising:\n obtaining a mesh representing an environment; receiving a plurality of images representing the environment from an image capture device; determining a first location of a first light source illuminating the environment; projecting a ray originating from the first location of the first light source onto the mesh; determining, based at least in part on an intersection point between the ray and the mesh, a candidate shadow region in an image of the plurality of images; determining, based at least in part on the intersection point, a second location of a second light source for illuminating the candidate shadow region; selecting an additional image of the plurality of images based at least in part on the second location of the second light source; and generating, based at least in part on the candidate shadow region and the additional image, an updated image representing the environment, the updated image corresponding to the image with one or more shadows at least partially modified.
