METHOD FOR MEASURING HEIGHT BY IMAGE AND MOVABLE ROBOT APPARATUS

摘要

The present invention relates to a height measuring method for measuring the height of a user by analyzing a user′s image photographed by a camera and a device therefor. A movable robot device according to the present invention comprises: the camera; a display part for outputting the image obtained by the camera in real time; a storage part for storing the actual height from a reference line to the top of the photographed image; and a height measurement part. The height measurement part displays the reference line on the real-time image and recognizes the top of a user′s head on the image by photographing the user positioned on the reference line. And then, it checks a ratio of the height of the top of the head to the height from the reference line to the top of the photographed image. Accordingly, the height measurement part measures the height of the user based on the checked ratio and the actual height from the reference line to the top of the photographed image, which is stored in the storage part.
