Description

The virtual studio which can make composite real image and computer graphics is indispensable equipments for broadcasting stations. However, it's difficult to use handy type cameras in such kind of studios, because it requires the precise camera movement data. So, we devised the new sensor which could measure angle and the 3 dimensional position of the camera, using Micro Electro Mechanical Systems (MEMS) and Particle Image Velocimetry (PIV) technology. We clarified the method of MEMS's noise control, and the development of a new image processing algorithm, we can get precision around 0.2[deg] by the new MEMS sensor, and within 3% to moving distance in a rate of 59.94[Hz] (video rate) by PIV process.
