To develop a quick detection algorithm for the image-based autonomous vehicle (AV) or computer assisted driving system, this paper proposes a real-time object detection method using two coordinated cameras. The mapping between two simultaneous images from the two cameras and coordination of the virtual sensitive areas can be resolved using parameters like the camera shot angle, the camera focal length,...
The information of vehicle is very important for maintaining traffic order under the present complex traffic environments. The image of vehicle is captured in various ways; fixed camera, movable camera, and vehicle-loaded camera. This paper proposes a new vehicle plate recognition mechanism that is essential to know the information of vehicle. The proposed method is a real-time processing system using...

This paper presents the installation, mechanical design and processing of intelligent vehicle electronic steering control system. According to the characteristics of intelligent vehicle, the neural networks steering control model is designed, programmed and implemented...
Focusing on the problem that the detection accuracy of traffic detection system is sensitive to the changes of complex environments, this paper presents an improved method of vehicle detection. It builds and updates the background adaptively. Additionally, to improve the computation efficiency of shadow elimination, a fast algorithm of neighbor mean based on HSV model is proposed. As the occlusion...
This paper presents a configuration control of a forklift vehicle using a camera-based vision system with limited angle-of-view (AOV). The configuration (i.e., position and orientation) of the vehicle is transformed to navigation variables, which are the distance left to the goal position, the angle made by the x-axis of the target coordinate and the vehicle-to-target (v-to-t) vector, and the angle...
This paper presents target motion estimation for multiple air vehicles. The motion of the airborne target is estimated by vision information from camera sensors fixed to the followers. Each camera sensors provides information of the target by three angles: an azimuth angle, an elevation angle, and a subtended angle. In the frame work of information filter, each follower estimates position, velocity...
Measuring a vehicle's speed using a video image is an important technique in an intelligent transportation system. This paper presents a hardware implemented vehicle speed measurement (VSM) system. The operation of the system consists of three steps. First, we remove vehicles from a series of captured images to create a background. To do this, we introduce a simplified exclusion algorithm optimized...
In recent years owing to the development of computer hardware and image processing technology, the researches to build control system using a vision sensor are stimulated. Vision sensors provide additional information about the environment of the workplace as well as afford position information of an object. However, a vision sensor is sensitive to surrounding environment such as intensity, diffusion...
The process of the alternative functioning of the mobile phones shall be detailed keeping in mind that these devices have less memory and less computing capacity. A simple background subtraction algorithm process may be used, that projects a moving object in consideration to be in the current view, when the subtraction of the current captured image and the background reaches a certain threshold. We...
We propose a distributed algorithm for estimating the poses (positions and orientations) of multiple autonomous vehicles in GPS denied scenarios when pairs of vehicles can measure each other's relative pose in their local coordinates. Currently, navigation of an autonomous vehicle in GPS denied scenarios is achieved by integrating relative pose measurements between successive time instants that are...
Increasingly powerful integrated circuits are making an entire range of new applications possible. Recent technological advances are enabling a new generation of smart cameras that represent a quantum leap in sophistication. While todaypsilas digital cameras capture images, smart camera capture high-level descriptions of the scene and analyze what they see. A smart camera combines video sensing, high-level...
