Abstract

The present invention relates to an apparatus and a method for multiple-touch three-dimensional contactless control for spatial sensing. The apparatus comprises two cameras (101, 102) having spatial sensors to capture object position in a form of an image, a register for registering the spatial directions as sensed by the spatial sensors, a data processing unit, and a computer for computing object point derivation and blob analysis. The method multiple- touch three-dimensional contactless control for spatial sensing comprising the steps of: positioning first and second camera (101, 102) and capturing image data of an object (107) by the cameras (101, 102); transferring the captured image data of the object (107) through background and foreground segmentation using image processing function; determining spatial positions of each of the image data of the object (107) and deriving a three-dimensional spatial position of the point; and processing the captured image data through blob analysis.
