Solving both problems together from camera images is known as SLAM, short for simultaneous localization and mapping. The cameras used here record a normal colour image together with the distance to everything in view; such devices are called depth cameras, or RGB-D cameras, and they suit indoor robots because they provide both appearance and scale without the cost of a laser scanner. Many open-source SLAM systems exist, and they differ considerably in how they store the map, how they recognize a place already visited, how much computing power they require, and how well they cope with dim light or rapid motion.
