20150070682 | APPARATUS AND METHOD FOR RECOGNIZING OBSTACLE USING LASER SCANNER - An apparatus and method for recognizing an obstacle using a laser scanner are provided. The apparatus includes a laser scanner that is installed at the front of a traveling vehicle and is configured to acquire laser scanner data configured of multiple layers in real time and an imaging device installed at the front of the moving object and is configured to acquire video data. A controller is configured to divide first laser scanner data item and second laser scanner data item acquired by the laser scanner into multiple layers to extract measurement data items each existing in the respective layers and is configured to compare the measurement data items in the same layer of the multiple layers to determine whether an obstacle is present ahead of the traveling vehicle. Additionally, the controller is configured to combine the laser scanner data reflecting whether an obstacle is present with the video data. | 03-12-2015 |
