We describe a novel automatic calibration method using a single camera for a multiple-projector spherical Fish Tank Virtual Reality (FTVR) display. Modeling the projector as an inverse camera, we estimate the intrinsic and extrinsic projector parameters automatically using a set of projected images on the spherical screen. A calibrated camera is placed beneath to observe partially visible projected...
We describe an auto-calibrated 3D perspective-corrected spherical display that uses multiple rear projected pico-projectors. The display system is auto-calibrated via 3D reconstruction of each projected pixel on the display using a single inexpensive camera. With the automatic calibration, the multiple-projector system supports a seamless blended imagery on the spherical screen. Furthermore, we incorporate...
Industrial robots are widely used in industrial area. Requirements for more accuracy and stable performance are raised in the applications. Especially when the robot executes machining task, the dynamic performance in the machining process has influence on the work piece quality. This article utilizes a high speed camera measuring system to analyze the robot motion for the sake of process improvement...
