1. Which explanation matches find a planar marker?A. Camera pose estimates position and orientation relative to known 3D or planar geometry.B. Graphics must use the estimated pose, camera intrinsics, and consistent coordinate frames.C. Known planar marker corners provide correspondences between marker coordinates and the image.D. Pose quality should be tested across movement, occlusion, and illumination conditions.

2. Which explanation matches estimate camera pose from geometry?A. Known planar marker corners provide correspondences between marker coordinates and the image.B. Camera pose estimates position and orientation relative to known 3D or planar geometry.C. Graphics must use the estimated pose, camera intrinsics, and consistent coordinate frames.D. Pose quality should be tested across movement, occlusion, and illumination conditions.

3. Which explanation matches place graphics in the camera view?A. Graphics must use the estimated pose, camera intrinsics, and consistent coordinate frames.B. Known planar marker corners provide correspondences between marker coordinates and the image.C. Camera pose estimates position and orientation relative to known 3D or planar geometry.D. Pose quality should be tested across movement, occlusion, and illumination conditions.

4. For estimate camera pose from geometry, which result or action fits this practical case: A virtual caption should follow the exhibit as the camera moves.A. Detect four corners and check their ordering before estimating the mapping.B. Project one fixed world anchor each frame and test whether it remains beside the exhibit.C. Record reprojection error and failure rate for slow and fast camera turns.D. Project known marker corners using the candidate pose and compare them with observed pixels.

5. For test pose under motion and poor light, which result or action fits this practical case: Motion blur and dim lighting make the marker hard to find.A. Detect four corners and check their ordering before estimating the mapping.B. Project known marker corners using the candidate pose and compare them with observed pixels.C. Record reprojection error and failure rate for slow and fast camera turns.D. Project one fixed world anchor each frame and test whether it remains beside the exhibit.
