We describe an auto-calibrated 3D perspective-corrected spherical display that uses multiple rear projected pico-projectors. The system is via reconstruction of each pixel on the using a single inexpensive camera. With automatic calibration, multiple-projector supports seamless blended imagery screen. Furthermore, we incorporate head tracking with to present content motion parallax by rendering images based viewpoint. To show effectiveness this design, implemented view-dependent application...
We describe a novel automatic calibration method using single camera for multiple-projector spherical Fish Tank Virtual Reality (FTVR) display. Modeling the projector as an inverse camera, we estimate intrinsic and extrinsic parameters automatically set of projected images on screen. A calibrated is placed beneath to observe partially visible patterns. Using correspondence between observed pattern pattern, reconstruct shape display finally recover 3D position each pixel Additionally present...
<title>Abstract</title> Non-destructive, rapid, and accurate detection of the nutritional compositions in sorghum is great significance to application agricultural production food industry. In process nutrition detection, it can obtain good effect by extracting corresponding characteristic wavelengths selecting suitable model for different nutrients. this study, crude protein, tannin, fat contents variety samples were taken as research object. Firstly, visible near-infrared(Vis-NIR)...
In this paper, a method based on point source and view-window is proposed that covers the features as full parallax, depth accurate occlusion cue, shading lighting, ensures computational efficiency in meantime, to calculate on-the-fly computer-generated holograms. With acceleration of graphics processing unit (GPU), bunch data reconstructed image go through pipeline OpenGL finish with coordinates transformation, fragment interpolation, lighting calculation, test, calculation superposition...
