This study proposes an adaptive Lane Departure Warning system (LDW) on smartphone, to deal with flexible warning capability for different road environment and driver behavior. The proposed system is migrated the preliminary developed LDW algorithm and utilizing mobile camera built-in Android smartphone to capture images of road environment. Through "Java Call C" approach, the LDW kernel...
Based on the lane marking tracking, this study presents a robust tracking approach for vision-based forward vehicle detection. Following vanishing point of lane which is according to lane detection point and linear regression analysis, five scan lines created as region of interest (ROI) for tracking is adopted to reduce the computational cost in detection process. The proposed algorithm implemented...
An image based distance self-calibrating method for automotive electronic system is proposed to ease the difficulty in setup procedure and offset the possible changes caused by moving the camera that used to capture image for distance measurement. By process the information from vertical edge of dashed road line, the lookup table is established to translate the pixel distance to real distance. The...
This study presents an effective vehicle detection and tracking approach to deal with forward collision warning (FCW) system. Based on robust lane-marking tracking and vanishing point, a regions of interest (ROI) is created for detecting whether vehicle in the front. The proposed method is implemented in TI DM648 DSP embedded system, and get very good result in the highway. In particular, when the...
A fast lane departure warning system which realized in embedded system is presented in this paper. Based on small process area of image and Nearest Near Peak (NNP), the lane-marking detection and tracking process can extract lane-marking pattern fast. Further, the dynamic vanishing point is employed to fine-tuning both of sides for lane-marking results. Finally, the departure alarm is active when...
Based on lane-marking tracking with fuzzy adjustable vanishing point mechanism, this paper presents robustness forward vehicle detection system. Compared to most of the detection systems with a large curvature of road trend, which are not effective for the routes to detection and marking. Therefore, follow the current image frame, the proposed system calculate the error between lane detection point...
This paper focuses on vehicle warning system based on fuzzy decision making for lane departure and forward collision avoidance for dealing with driver assistant system. The proposed system is composed of vision-based preprocessing and a fuzzy decision making. The objective of vision-based preprocessing part is lane tracking and forward vehicle detection, and provides the necessary information for...
