The Brown Range Image Database contains 197 range images collected by Ann Lee and Jinggang Huang. Some preliminary analysis on these images were presented at CVPR, South Carolina, June 2000, and ICCV (2nd Int'l Workshop on Statistical and Computational Theories of Vision), Vancouver, July 2001. The images have been collected with a laser range-finder with a rotating mirror (3D imaging sensor LMS-Z210 by Riegl). Each image contains 444x1440 measurements with an angular separation of 0.18 deg. The field of view is thus 80 degrees vertically and 259 degrees horizontally. Each measurement is calculated from the time of flight of the laser beam. The operational range of the sensor is typically 2-200m. The laser wavelength of the range-finder is 0.9 mu m, which is in the near infra-red region. The data set consists of images which can be categorized as "forest", "residential", and "interior" scenes. All range image files are stored in a binary format and can be found in the directory binary/. Each image is represented in terms of 16 bit unsigned integer (uint16) elements stored by big-endian byte ordering.
