A new form of optical wireless communication is presented in this paper. The proposed method is developed from a cheap and simple technology of two dimensional barcode where the data is easily obtained just by using a camera equipped smart phone. In this paper, a computer monitor is used for displaying spatial modulation images and a webcamera is used as a receiver. Consequently, the acquired images...
A new formulation of 3D modeling using signal processing and calibration of individual frames is proposed. The scheme eliminates the need of the pre-knowledge of the camera position relatively to the source and the object. The experiment performed on primitive geometries and real world objects show qualitatively that the system can give up to ± 0.1 mm accuracy.
