Information processing device and information processing method

2:

• The information processing device according to claim 1, wherein the registration information generation unit classifies some of the keyframes into a group prohibiting discard.

3:

• The information processing device according to claim 2, wherein the registration information generation unit selects the keyframe classified into the group prohibiting discard, on a basis of distribution of states of the device produced when the respective keyframes are captured.

4:

• The information processing device according to claim 3, wherein the registration information generation unit selects one of the keyframes captured in respective directions in division areas defined by dividing a space by yaw directions around the device with an axis aligned with a gravity direction, and classifies the selected one keyframe into the group prohibiting discard.

5:

• The information processing device according to anyone in claim 1, wherein the registration information generation unit classifies the keyframes on a basis of at least any one of the number of extracted feature points, an acquisition time point, the number of times of use for collation, and a difference between a state of the device at a time of imaging and other states.

6:

• The information processing device according to claim 1, wherein the registration information generation unit discards the keyframe registered first in the keyframes previously registered and belonging to one of the groups at the time of an excess of a registration upper limit of the keyframes due to registration of the new keyframe.

7:

• The information processing device according to claim 1, wherein the state information acquisition unit acquires the state information on a basis of the moving image that indicates a space around a user wearing a head mounted display as the device and that is captured by movement of the user.

8:

• The information processing device according to claim 7, further comprising:
• a play area control unit that sets a play area where the user is movable, on a basis of an environment map having a three-dimensional structure, including a set of the points, and constructed together with the state information, wherein
• the registration information generation unit selects the keyframe classified into a group prohibiting discard from frames of the moving image captured at a time of setting of the play area.

9:

• The information processing device according to claim 7, further comprising:
• an application execution unit that forms a display image in a visual field corresponding to a visual line of the user on a basis of state information regarding the head mounted display, wherein
• the state information acquisition unit acquires the state information regarding the head mounted display by using data of the keyframes stored in the registration information storage unit before the application execution unit starts processing.
