CAMERA BASED RADAR BLOCKAGE DETECTION

摘要

In automotive applications, software based methods using algorithms and system modifiable calibration parameters exist to detect the blockage of the field ot view of vehicle mounted sensors, such as radar sensors. However, these existing techniques have limitations with respect to classification of blockages and large delays before blockages are detected. Besides, if there are some minor or insubstantial (e.g., thin) objects obscuring the sensor, such as a wire running over the radar, the software techniques may not be sufficiently sensitive to detect such blockages.
