LiDAR

SpaceGrid provides a complete LiDAR mapping solution. It conducts mapping in all terrains and after detailed processing provides a dense 3D point cloud having photographic quality, 360° panoramic HD video/pictures with time stamp, as built drawing, topographical and terrain model. For this, company uses high end hardware incorporated with latest technology. Our survey acuracies are most suitable for highway dpr projects. For terrestrial LiDAR mapping we use the following equipment’s:

  1. Velodyne – HD32
  2. IMU – Oxts X-Nav200
  3. Camera – GoLook 360
  4. GNSS Receiver – CHC – X900S

Velodyne HD32 Lidar Scanner

The Veodyne HDL-32E LiDAR sensor is small, lightweight, ruggedly built and features up to 32 lasers across a 40° vertical and 360° horizontal field of view. It is designed to capture 7,00,000 points per second within 80-100m radius providing a dense point cloud. Power consumption being minimal and weighing 1kg, it can be mounted on almost all vehicles and is accurate in all terrain.

IMU - OXTIS X-Nav200

The xNAV200 is a small GPS/INS system which is ideal for all size and weight constrained applications. The system is designed to deliver superior position, roll/pitch and heading data even in challenging operating environments. 4 GB of on-board storage is available, allowing four days' worth of measurements to be stored internally

360 Degree HD Camera - GoLook

The GoLook camera system combines seven (7) 1080p HD video cameras capturing 30fps into a synchronized, calibrated photogrammetric video imaging system. GoLook has a full 360 degree horizontal FOV. A simple GPS system is built-in such that street view data can be generated directly without any additional equipment. In addition it accurately time stamps all imagery making it possible to bore sight with a more accurate trajectory solution.

GNSS Receiver - CHC X900S-OPUS

The CHC X900SOPUS dual frequency GNSS receiver is designed to deliver high precision, robust performances and reliable technology. The GNSS raw data recording starts automatically and will stop when the receiver is powered off. The combination of L1/L2 GNSS technology and advanced post processing software allows baselines computation up to 100 km. Compact design of 179 x 84 mm (7.0 x 3.3 in) with less than 1,4 kg (49 oz) makes the it an easy to carry GNSS receiver for everyday field work.
