A METHOD FOR CREATING TONES BASED ON THE SENSED POSITION OF THE BODIES IN THE SPACE AND A DEVICE FOR IMPLEMENTING THE METHOD

摘要

"Objects-of-Interest" are scanned in space (spatially), and the height of the generated tones, their colour and their loudness are all assigned according to the spatial coordinates of these objects. The coordinates of the object are determined based on the machine-vision camera system principle, where at least one camera scans a scene in which there are "objects-of-interest" that differ from the surrounding environment - and other objects with their characteristic colour, shape, and/or dimensions. Each single snapshot is pre-processed by segmenting the image based on the occurrence of a given colour by the user setting the acceptable range of individual colour coordinates. Each "object-of- interest" is determined by its momentary characteristics - which determine the area of the object in the image and two spatial coordinates of the centre of gravity. The third spatial coordinate of the centre of gravity of an object is determined - in the case of a one -camera image capture, after initial calibration according to the size of the area of the "object-of-interest" in the image. In the case of captures by at least two cameras, the coordinate is determined by the superposition of the images from different cameras, taken at the same time.
