Environment Mapping with Automatic Motion Model Selection
First Claim
1. A method comprising:
- receiving a video frame captured by a camera device into memory;
estimating a type of motion relative to 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, adding the received video frame to the current keyframe group; and
when the type of motion is not the same motion type of the current keyframe group held in memory, creating a new keyframe group in memory and adding the received video frame to the new keyframe group.

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.

10. A non-transitory computer readable medium, with instructions stored thereon, which when executed by the at least one processor cause a computing device to perform data processing activities, the data processing activities comprising:
-
receiving a video frame captured by a camera device into memory; identifying features in the received video frame; 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, adding the received video frame to the current keyframe group; and when the type of motion is not the same motion type of the current keyframe group held in memory, creating a new keyframe group in memory and adding the received video frame to the new keyframe group. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A device comprising:
-
at least one processor; at least one memory; and an instruction set, stored in the at least one memory and executable by the at least one processor to perform data processing activities, the data processing activities comprising; executing a tracking process including; receiving a video frame into the at least one memory; estimating a type of motion from a previously received video frame held in the at least one memory to the received video frame; when the type of motion is the same as motion type of a current keyframe group held in the at least one memory, adding the received video frame to the current keyframe group; and when the type of motion is not the same motion type of the current keyframe group, creating a new keyframe group in the at least one memory and adding the received video frame to the new keyframe group. - View Dependent Claims (18, 19, 20)
