Pearson's Correlation Coefficient for Discarding Redundant Information: Velodyne Lidar Data Analysis

摘要

Energy limitation is one of the most important challenges. Many applications are being developed and one important aspect is the excess of information, frequently redundant, that imposes a great computational cost in data processing and consequently power consummation. Management of all power resources is therefore important for intelligent vehicles and mobile robots. In previous works, we have proposed a discarding method as a simple solution to improve the performance of a real-time navigation system. The objective in this paper is to analyze the performance of the discarding criteria with a Velodyne sensor, a light detection and ranging (LIDAR) system, which generates around 1.3 million points per second.
