DISTANCE MEASUREMENT APPARATUS OF AN IMAGE PROCESSING-BASED

摘要

The present invention relates to a distance measurement apparatus of an image processing-based which is configured such that the distance to an object can be measured accurately through an image processing based on real size data of a laser pointer image, width size data of a laser pointer image displayed on a screen, and focus distance of a camera in order to use an augmented reality, calculate space data and materialize building information modeling (BIM) comprising: a laser pointer to project visible light of a laser beam; a camera photographing laser pointer images formed by the laser pointer; a memory to store real size data of the laser pointer images and focus distance data when adjusting a focus; and a controlling part to control display of a laser beam filmed by the camera and calculate a distance based on width size data of a laser pointer image displayed on a screen, real size data of a laser pointer image, and focus distance data.
