SLAM stands for simultaneous localization and mapping. It’s a technology method used in autonomous systems for creating a map in the unknown environment or updating an existing map in the known environment while continuous tracking a current location. Augmented reality mobile apps rely on SLAM to determine where to put virtual content to ensure it perfectly fits real environment objects. Simultaneous localization and mapping is also a technology behind self-driving cars that use this method to create a virtual 3D copy of the physical environment and “understand” road conditions that include pedestrians, vehicles, obstacles, and other objects.
