Abstract: Techniques are provided to reduce power consumption when performing surface reconstruction. A surface mesh of an environment is generated, where the surface mesh is generated from multiple depth maps that are obtained of the environment. After the surface mesh is generated, a change detection image of that environment is captured while refraining from obtaining a new depth map of the environment. The change detection image is compared to the surface mesh. If a difference between the change detection image and the surface mesh is detected and if that difference satisfies a pre-determined difference threshold, then a new depth map of the environment is obtained. The surface mesh is then updated using the new depth map.
