This paper presents an early research on the route recommendation system based on street view images. It consists of three primary functions. (1) Data collection: The user selects a path using a graphical user interface and download all street view images for the path. (2) Road surface extraction: The vanishing point in the image is obtained according to the road surface region segmentation by local...
Lane departure and forward collision detection plays an important role in autonomous driving and commercial driver-assistance systems. This paper presents an integrative approach to vision-based lane departure detection which aims to be as simple as possible to enable the real-time computation while being able to adapt to a variety of highway and urban scenarios on different weather conditions. In...
Tennis is an interesting racket sport played by millions of recreational and professional players and is also a very popular worldwide spectator sport. Players ranging from the beginners to the professionals usually require a lot of practices. At the end of such practices, the tennis balls are usually scattered randomly over the surface of the tennis court, hence, it is time consuming and annoying...
In this paper, we implement a path planning algorithm and combine with an obstacle avoidance system for a small commercial quadrotor vehicle. To keep the flight safe, the quadrotor navigates with the vision information for obstacle detection. A sequence of images are captured from the onboard camera and used for visual guidance. The optical flow is computed from the images and the derived depth cues...
