High quality road and track maps are an important factor in vehicle localization, since it allows for non-linear localization algorithms, such as Particle Filter and Extended Kalman Filter, to be run with over-the-shelf mobile sensing products. The current paper studies and experiments with a low-cost methodology of annotating open-source topological maps, with large quantities of crowd sourced sensor...
With the rapid increase of image sensors resolution, some pressure moved on compression algorithms again. Fractal compression is known to provide good performance in terms of compression ratio. But more than ever, the focus is on execution time of these algorithms. Large and fast access memories are hard to provide and very expensive. Therefore, a fast compression algorithm can reduce the expensive...
More than 50% of the motorcycle accidents are fatal for the rider. 70% of those are due to the time needed for the emergency service to arrive at the accident. This leads us to a necessity in finding a device able to detect accidents. This document explains how to use the MPU6050 IMU sensor in an embedded device for measuring the Euler angles (roll, pitch, yaw) and also the G Forces on different axes.
