Terrain modeling and building reconstruction requires interpretation of millions of points acquired by terrestrial and airborne laser scanners. Nearest neighbors search is often used in LiDAR data processing based computation of local features in 3D space. Kd-tree and range tree etc. are usually employed for range search. In this paper we investige the feasibility of Locality Sensitive Hashing (LSH)...
In order to meet the requirement of large data processing and high speed data exchanging between the host computer and electrical instruments, a scenario about data communication system based on USB interface is designed and realized. The basic communication system configuration and architecture are discussed. The detail of hardware interface about a specific USB controller chip PIDUSBD12 is described...
