If you use these databases in your research, we kindly ask that you reference this webpage and our papers relevant to each database. Please find the corresponding information below to download the databases. We are making the databases available to the research community free of charge. The natural environments where the image and range data were collected cover areas around Austin, Texas, including the campus at The University of Texas and the Texas State Capitol. ![]() Finally, to obtain the aligned 2D range map with the 2D image, the 3D point clouds are projected and transformed into the 2D range map by applying the pinhole camera model with lens distortion. The acquired range data are exported from the range scanner as point clouds with three-dimensional coordinates and range values, while the image data are stored in the digital camera. Next, to acquire the image and range data in natural scenes, the device obtains distances by lidar reflection and waveform analysis as it rotates, and then the digital camera takes an optical photograph with the same field of view. The mounting calibration is done manually using the RIEGL RiSCAN PRO software, which is designed for scanner operation and data processing. Since there are inevitable translational and rotational shifts when mounting the camera onto the range scanner, calibration is performed before data acquisition. The image and range data in the LIVE Color+3D Database were collected using an advanced range scanner, RIEGL VZ-400, with a Nikon D700 digital camera mounted on top of it. The LIVE Color+3D Database consists of accurately co-registered color images and ground-truth range maps at high-definition resolutions. Towards obtaining a better understanding of the statistical relationships between color and range, we constructed the LIVE Color+3D Database. Therefore, interaction and correlation between color and depth need further examination. ![]() Moreover, it has been demonstrated that the perception of color and depth are related, and that chromatic information can be used to improve the solution of stereo correspondence problems. ![]() Hence, comparisons of the outputs of the different cone types by the retinal ganglion cells allow dense spatiotemporal chromatic information to be transmitted from the retina to the primary visual cortex (V1).Ĭolor can be used at later visual processing stages to help infer large-scale shape information to better solve visual tasks by both humans and machine algorithms. While the cones themselves do not encode color, they do come in three types that have different spectral sensitivities. The cone photoreceptors, which are densely distributed in the fovea centralis of the retina, capture and convey rich information both in space and time. The LIVE 3D databases are constructed in collaboration with Center for Perceptual Systems (CPS,Ĭolor is an important and dense natural visual cue that is used by the brain to reconstruct both low-level and high-level visual percepts.
