Description: This plugin allows you to calculate 3D data out of 2D scanline data captured with a laserscanner. Limitations: This version is only working correctly for laser installation on the left side. Calculation of 3D data from 2D image stacks captured by a laser scanner Open your original distort stack Start the plugin Scan_Calculation Clicking the plugin Scan_Calculator you will start up in the main menu which is split in two different sections. In the upper section you can check and edit the basic scanner setup data. Scan_Calculator – Maim menu Change to the Camera Prefs Menu Camera Prefs – parameters for undistortion of images (zhang calibration parameters) Definition of 3D bounding box

CAVE | Projects: Diffuse Structured Light Today, structured light systems are widely used in applications such as robotic assembly, visual inspection, surgery, entertainment, games and digitization of cultural heritage. Current structured light methods are faced with two serious limitations. First, they are unable to cope with scene regions that produce strong highlights due to specular reflection. Second, they cannot recover useful information for regions that lie within shadows. Examples are shown in the above figure - a metal hemisphere (specularities) and a cube (shadows). We propose diffuse structured light, a simple but effective approach to mitigate both specularities and shadows in structured light methods.
