Practical techniques for improving sensor fusion accuracy In addition to the usual design techniques for improving sensor performance such as (1) calibration to correct errors including multi-point calibration for higher accuracy, and regular recalibration to correct for drift over time; (2) signal conditioning to correct for errors like offset and linearity, amplified signals for improved signal-to-noise […]
LIDAR
Key Considerations for integrating LiDAR and radar data for robust perception: part 1
For autonomous vehicle (AV) applications, both radar and LiDAR (light detection and ranging) are often used in addition to high-definition cameras and other sensors. The proper fusion of the output from these devices enables the detection of obstacles, identification of lane markings, and the accurate recognition of other vehicles and pedestrians. The radio waves (typically […]
What do the latest imaging systems in airborne objects reveal? Part 2
Archeological searching is being conducted from above at altitudes well below those of satellite orbits. One group of researchers has used an airborne laser scanner (ALS) mounted to a helicopter’s skid pad to reveal several cities between 900 and 1,400 years old beneath the tropical forest floor in Cambodia. The first LiDAR (light detection and […]
Using LIDAR for Transmission Power Lines
Dave Brown of Terra Remote Sensing explains the use of LIDAR (Light Detection And Ranging) technology to Randy Frank at the IEEE 2011 Power Systems Conference & Expo (PSCE) held March 20-23, 2011, in Phoenix, AZ. LIDAR is being widely used by utility companies to map transmission lines for adverse conditions and vegetation. For more […]
