Abstract: A dense point cloud (DPC) is generated for a physical object. 2D digital images of the physical object are obtained. Object extractors are defined. A sparse point cloud (SPC) is created from the 2D digital images. A modified SPC is obtained by first applying the object extractors to the 2D digital images to exclude pixels from the 2D digital images and then excluding the datapoints in the SPC that correspond to the pixels that have been excluded from the 2D digital images. The datapoints of the SPC that do not represent the object are excluded from being included in the modified SPC. The DPC is generated by integrating information obtained from the pixels in the 2D digital images with the modified SPC.

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.
