and visually presenting, via a display of the augmented reality device, an augmented-reality view of the physical space including a predetermined pose cue indicating a predetermined pose in the physical space and a current pose cue indicating the current pose in the physical space. ### Claim 2 (depends on 1) The method of claim 1, wherein the predetermined pose cue has a world-locked position that is fixed relative to the physical space, and wherein the current pose cue has a device-locked position that changes with the current pose of the augmented-reality device. ### Claim 3 (depends on 1) The augmented-reality device of claim 1, wherein the predetermined pose is determined, via a pose sensing system of the augmented-reality device, during capture of a previously-captured image of the physical space. ### Claim 4 (depends on 1) The method of claim 1, further comprising: visually presenting, via the display, a visual alignment cue indicating that the current pose cue is at least partially aligned with the predetermined pose cue. ### Claim 5 (depends on 1) The method of claim 1, further comprising: audibly presenting, via an audio speaker of the augmented-reality device, an audio alignment cue indicating that the current pose cue is at least partially aligned with the predetermined pose cue. ### Claim 6 (depends on 1) The method of claim 1, further comprising: capturing, via a camera of the augmented-reality device, a first image at a first time while the current pose cue is aligned with the predetermined pose cue; and capturing, via the camera, a second image at a second time subsequent to the first time while the current pose cue is aligned with the predetermined pose cue. ### Claim 7 (depends on 1) The method of claim 1, wherein the predetermined pose cue is a first predetermined pose cue, and wherein the method further comprises: capturing, via a camera of the augmented-reality device, a first image while the current pose cue is aligned with the first predetermined pose cue; visually presenting, via the display, a second predetermined pose cue different than the first predetermined pose cue; and capturing, via the camera, a second image while the current pose cue is aligned with the second predetermined pose cue. ### Claim 8 An augmented-reality device, comprising: a camera configured to image a physical space; a pose sensing system configured to determine a current pose of the augmented-reality device in the physical space; a display; a logic machine; and a storage machine holding instructions executable by the logic machine to: receive a predetermined pose in the physical space; and visually present, via the display, an augmented-reality view of the physical space including a predetermined pose cue indicating the predetermined pose in the physical space and a current pose cue indicating the current pose in the physical space. ### Claim 9 (depends on 8) The augmented-reality device of claim 8, wherein the predetermined pose cue has a world-locked position that is fixed relative to the physical space, and wherein the current pose cue has a device-locked position that changes with the current pose of the augmented-reality device. ### Claim 10 (depends on 8) The augmented-reality device of claim 8, wherein the storage machine further holds instructions executable by the logic machine to: visually present, via the display, a visual alignment cue indicating that the current pose cue is at least partially aligned with the predetermined pose cue. ### Claim 11 (depends on 10) The augmented-reality device of claim 10, wherein the predetermined pose cue, the current pose cue, and the visual alignment cue are visually different from each other. ### Claim 12 (depends on 8) The augmented-reality device of claim 8, further comprising: an audio speaker; and wherein the storage machine further holds instructions executable by the logic machine to: audibly present, via the audio speaker, an audio alignment cue indicating that the current pose cue is at least partially aligned with the predetermined pose cue. ### Claim 13 (depends on 8) The augmented-reality device of claim 8, wherein the predetermined pose is determined, via the pose sensing system, during capture of a previously-captured image of the physical space. ### Claim 14 (depends on 13) The augmented-reality device of claim 13, wherein the predetermined pose cue includes the previously-captured image with a world-locked position at the predetermined pose. ### Claim 15 (depends on 8) The augmented-reality device of claim 8, wherein the predetermined pose cue at least partially indicates a field of view from the predetermined pose, and wherein the current pose cue at least partially indicates a field of view of the current pose. ### Claim 16 (depends on 8) The augmented-reality device of claim 8, wherein the predetermined pose cue includes a first set of coplanar markers, and wherein the current pose cue includes a second set of coplanar markers. ### Claim 17 (depends on 8) The augmented-reality device of claim 8, wherein the storage machine further holds instructions executable by the logic machine to: capture, via the camera, a first image of the physical space at a first time while the current pose cue is aligned with the predetermined pose cue in the augmented-reality view, and capture, via the camera, a second image of the physical space at a second time subsequent to the first time while the current pose cue is aligned with the predetermined pose cue in the augmented-reality view. ### Claim 18 (depends on 8) The augmented-reality device of claim 8, wherein the predetermined pose cue is a first predetermined pose cue, and wherein the storage machine further holds instructions executable by the logic machine to: capture, via the camera, a first image of the physical space while the current pose cue is aligned with the first predetermined pose cue; visually present, via the display, a second predetermined pose cue different than the first predetermined pose cue; and capture, via the camera, a second image while the current pose cue is aligned with the second predetermined pose cue. ### Claim 19 A method comprising: receiving a previous pose assumed by an augmented-reality device during capture of a previously-captured image of a physical space by a camera of the augmented-reality device; determining a current pose of the augmented reality device in the physical space; and visually presenting, via a display of the augmented reality device, an augmented-reality view of the physical space including a predetermined pose cue and a current pose cue, wherein the predetermined pose cue indicates the predetermined pose in the physical space and has a world-locked position that is fixed relative to the physical space, and wherein the current pose cue indicates the current pose in the physical space and has a device-locked position that changes with the current pose of the augmented-reality device. ### Claim 20 (depends on 19) The method of claim 19, further comprising: visually presenting, via the display, a visual alignment cue indicating that the current pose cue is at least partially aligned with the predetermined pose cue.
