  • Patent number: 10176386
    Abstract: A vehicle speed determination system and method receive image data of a field of view of a camera operably disposed onboard a vehicle. A speed and/or heading of the vehicle are determined as the vehicle is moving based at least in part on one or more differences in the image data. In one aspect, pixel intensities in different images or frames may be examined to identify one or more features of interest in the images or frames. Movement of the one or more features of interest in the images or frames is correlated to movement of the vehicle along the route, and the time difference between when the images or frames are obtained can be used to determine the vehicle speed.

  • Patent number: 8099213
    Abstract: A method is provided for detecting road-side edges in a road segment using a light-based sensing system. Input range data is captured using the light-based sensing system. An elevation-based road segment is generated based on the captured input range data. The elevation-based road segment is processed by filtering techniques to identify the road segment candidate region and by pattern recognition techniques to determine whether the candidate region is a road segment. The input range data is also projected onto the ground plane for further validation. The line representation of the projected points are identified. The line representation of the candidate regions is compared to a simple road/road-edge model in the top-down view to determine whether the candidate region is a road segment with its edges. The proposed method provides fast processing speeds and reliable detection performance for both road and road-side edges simultaneously in the captured range data.

  • Patent number: 8009024
    Abstract: A display device of the present invention is mounted on an automotive vehicle. An obstacle located in front of the vehicle is detected by a camera, and its features including speed, distance, size, etc. are analyzed by electronic circuits. An image showing the features of the front object is outputted from a liquid crystal panel. The outputted image is reflected on the windshield, displaying a virtual image to a driver. The virtual image is displayed in a form of a spot encircling the front obstacle seen through the windshield. The ways of displaying the encircling spot are variously changed according to a degree of collision danger that is determined according to a period in which the vehicle reaches the obstacle. For example, if the degree of collision danger is high, the spot is shown in red-orange color and/or with a high brightness. Thus, the driver easily recognizes the front obstacle in a high degree of collision danger.
