Abstract
Various embodiments each include at least one of systems, methods, devices, and software for environment mapping with automatic motion model selection. One embodiment in the form of a method includes receiving a video frame captured by a camera device into memory and estimating a type of motion from a previously received video frame held in memory to the received video frame. When the type of motion is the same as motion type of a current keyframe group held in memory, the method includes adding the received video frame to the current keyframe group. Conversely, when the type of motion is not the same motion type of the current keyframe group held in memory, the method includes creating a new keyframe group in memory and adding the received video frame to the new keyframe group.
