Abstract: There is provided mechanisms for aligning different DPCs of a physical object. A method is performed by an image processing device. The method comprises obtaining DPCs captured from different orbits around the physical object. The method comprises aligning the DPCs with each other. The method comprises selecting, in a first stage, a first DPC of the DPCs as a first reference DPC and individually aligning all remaining DPCs with the first ref-crence DPC, resulting in a first alignment of the DPCs. The first alignment of the DPCs yields a first value of an alignment metric per each of the DPC's except the first DPC. The method comprises selecting, in a second stage, a second DPC of the DPCs as a second reference DPC and individually aligning all remaining DPCs, except the first DPC, with the second reference DPC, resulting in a second alignment of the DPCs. The second alignment of the DPCs yields a second value of the alignment metric per each of the DPC's except the first DPC and the second DPC.

Abstract: An indoor distance measurement method includes, but is not limited to acquiring a horizontal distance between a camera on an Augmented Reality (AR) device and a target object and a height of the target object by using a direction sensor provided on an AR device. The method further includes, but is not limited to, superimposing and displaying the horizontal distance and the height of the target object on a real-world scene displayed by the AR device.
