Reflecting Surface

In recent years, Light Detection and Ranging (LiDAR) scanners have become more prevalent in the scientific community. They capture a “2.5-D” image of a scene by sending out thousands of laser pulses and using time-of-flight calculations to determine the distance to the first reflecting surface in the scene. Rather than setting up a collection of objects in real life and actually sending lasers into the scene, one can simply create a scene out of 3d models and “scan” it by casting rays at the models. This is a great resource for any researchers who work with 3D model/surface/point data and LiDAR data. The synthetic scanner can be used to produce data sets for which a ground truth is known in order to ensure algorithms are behaving properly before moving to “real” LiDAR scans. Also, noise can be added to the points to attempt to simulate a real LiDAR scan for researchers who do not have access to the very expensive equipment required to obtain real scans.

Introduces a kind of method that creating the point cloud for laser inner carving from texture of 3D model surface. At first, the 3D model surface with texture needs to be converted to the triangle faces. Then texture coordinates which corresponded to the vertex will be obtained by visiting the triangle faces. The transform from texture triangle surface to 3D model triangle surface will be completed next. Then the Bayer dithering algorithm should be applied to handle the texture image. At last, the inner carving point cloud will be gained by transforming from the surface texture space to the 3D model space.
