SPATIAL IMAGE DRAWING DEVICE FOR DRAWING OBJECTS BASED ON REFERENCE POINTS OF IMAGE

摘要

The present invention relates to a spatial image drawing device for drawing objects based on reference points of an image, which is capable of precisely adjusting the distances between stereo cameras. The stereo camera comprises: a left side camera and a right side camera, placed at regular intervals on the same line, for photographing images on the left and right side respectively with lenses and an image sensor; a camera moving device for adjusting the distance between the right and left side cameras by moving the cameras on a straight line based on the distance with an object; and a camera control device for computing an optical distance between the left and right side cameras based on the distance to an object included in an interesting area extracted by color images and depth images captured by the left and right side cameras and for transmitting driving signals to the camera moving device for the left and right side cameras to move according to the computed distance. Additionally, the camera control device comprises: an object extracting unit for extracting an object included in an interesting area using the depth and color images received by the left and right side cameras; a distance determining unit for determining the distance to the object using a differential value of the interesting area; a first adjusting unit for firstly adjusting the distance between the left side camera and the right side camera using the distance value of the object; and a second adjusting unit for readjusting the distance between the left side camera and the right side camera to correct the value if an error regarding the distance between the left side camera and the right side camera adjusted by the first adjusting unit occurs.;COPYRIGHT KIPO 2016
