Automobile navigation in tunnel environment is challenging. GPS sensors and ordinary cameras can't function effectively. For navigation, infrared cameras are installed on top of our experimental vehicle, and here we propose an efficient object detection method to detect emergency lights from the collected data in tunnel environment. The proposed method firstly detects keypoints by setting thresholds...
Indexing global-scale 3D vector data is a challenging task because more and more vector datum is used to analyze global problems. Various indices of 2D vector based on tree or grid structures have been approached. Although these indices may support 2D vector indices effectively, they do have some significant drawbacks for indexing global-scale 3D vector, such as critical spatial overlapping, unstable...
In the context of driving assistance, detection of moving targets is challenging when the automobile is witnessing very complex environment. The main challenges come from difficulties to tell foreground from moving background due to camera motion. We present an efficient method for target detection by hierarchically distinguishing the motion of targets from that of the background and using color information...
