A method of indoor distance measurement

Abstract

The invention discloses an indoor ranging method, which uses a direction sensor set on an AR device to obtain the horizontal distance between its camera and a target object and the height of the target object, and superimposes it on the scene in the real world displayed by the augmented reality device. . The present invention only acquires the angle between the line connecting the camera to the bottom of the target and the intersection point of the ground and the vertical direction of the ground or the angle between the line connecting the camera to the intersection of the extension line of the target and the ground and the vertical direction of the ground, and the angle between the camera and the top of the target. The angle between the connection line and the vertical direction of the ground, the angle between the line connecting the camera to the bottom of the target and the vertical direction of the ground, and then according to the vertical distance between the camera and the ground, the Pythagorean theorem can be used to calculate the distance between the camera and the target The calculation method of the horizontal distance and the height of the target object is simple and fast, with a small amount of calculation and low cost.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to an indoor distance measuring method. Background technique [0002] Augmented reality (Augmented Reality, referred to as AR) is to integrate the real environment and virtual auxiliary information objects through the computer to enhance the user's understanding and experience of the real world. Apply virtual information to the real world, and superimpose computer-generated virtual objects, scenes or system prompt information on the real scene, so as to realize the enhancement of reality. In the visual augmented reality, users use the head-mounted display to multiplex the real world and computer graphics, and then they can see the real world surrounding it. [0003] When the AR device is used outdoors, the location coordinates can be obtained by the GPS sensor, and the distance between the current AR device location and the target location can be calculated by the coordi...
