The proposed method firstly detects keypoints by setting thresholds for intensity of uniformly sampled points. Each keypoint is then verified by the appearance ...

Abstract: Automobile navigation in tunnel environment is challenging. GPS sensors and ordinary cameras can't function effectively.

Thus the method gives promising results in real time. Detection performance and efficiency are verified by experiments carried on challenging real data.

We propose a method to detect emergency lights for the navigation in the challenging tunnel environment. The method efficiently combines appearance and temporal ...

Jan 5, 2014 · For positioning we propose a method to detect emergency telephone indicators in a tunnel environment by using infrared cameras. The proposed ...

We evaluate our method based on detection performance and efficiency. Data To collect data, we mount an infrared camera on top of the experimental vehicle ...

Our detection scheme focuses on notifying the person about the disturbances in its path. Ultrasonic sensors are used to spot potholes, as they compute their ...

This paper describes an automatic method for the detection of tunnel luminaires as well as to easily obtain their 3D spatial location, using colored 3D point ...

This paper presents an integrated solution for the problem of detecting, tracking and identifying vehicles in a tunnel surveillance application, ...

One of the methods used by CIE to calculate visual adaptation is the L20 method, which considers the average luminance from environment, sky and road in a ...
