20100324796 | DRIVING SUPPORT DEVICE, DRIVING SUPPORT METHOD, AND DRIVING SUPPORT PROGRAM - A target vehicle speed of when a vehicle travels a predetermined forward section is acquired. An acceleration gear ratio for acceleration of the vehicle to reach a vehicle speed higher than the target vehicle speed after the travel of the predetermined section is acquired. The gear ratio of the vehicle is set to the acceleration gear ratio before the vehicle reaches the start point of the predetermined section. Before the vehicle reaches the start point of the predetermined section, the vehicle speed is lowered to the target vehicle speed. | 12-23-2010 |
20110242311 | IMAGE PROCESSING SYSTEM AND POSITION MEASUREMENT SYSTEM - An image processing system inputs a captured image of a scene viewed from a vehicle, extracts image feature points from the captured image, and obtains image-capturing situation information indicating a possibility that a specific subject is included in the captured image. The system determines importance degrees of the extracted image feature points based on the image-capturing situation information and generates image feature point data using the extracted image feature points based on the importance degrees. The system generates reference data by associating the image feature point data with image-capturing attribute information and creates a reference data database. The image-capturing attribute information includes an image-capturing position at which the image is captured to obtain the captured image corresponding to the image feature point data. | 10-06-2011 |
20110242319 | IMAGE PROCESSING SYSTEM AND POSITION MEASUREMENT SYSTEM - An image processing system temporarily stores, as processing target captured images, captured images whose image-capturing positions are included in a predetermined region. The system calculates similarity degrees of the processing target captured images, selects the processing target captured images whose similarity degrees are different from each other as useful images, and extracts image feature points from each of the useful images. The system generates image feature point data that includes the extracted image feature points, generates reference data used when scenic image recognition is performed by associating the generated image feature point data with an image-capturing position at which the image is captured to obtain the captured image corresponding to the image feature point data, and creates a reference data database. | 10-06-2011 |
20110243379 | VEHICLE POSITION DETECTION SYSTEM - A system stores reference data generated by associating image feature point data with an image-capturing position and a recorded vehicle event. The system generates data for matching by extracting image feature points from an actually-captured image. The system generates information on an actual vehicle event, extracts first reference data whose image-capturing position is located in a vicinity of an estimated position of the vehicle, and extracts second reference data that includes a recorded vehicle event that matches the actual vehicle event. The system performs matching between at least one of the first reference data and the second reference data, and the data for matching, and determines a position of the vehicle based on the matching. | 10-06-2011 |
20110243454 | VEHICLE POSITION RECOGNITION SYSTEM - A vehicle position recognition system calculates an estimated position of a vehicle based on satellite positioning and dead reckoning navigation, and calculates a basic error range in which there is a possibility that the vehicle exists. The system calculates an estimated error amount regarding a directional error factor. The directional error factor is an error factor that tends to cause an error in a specific direction with respect to a vehicle traveling direction. The estimated error amount is an estimated amount of the error that is caused by the directional error factor. The system adjusts the basic error range based on (1) a direction in which the error tends to be caused by the directional error factor and (2) the estimated error amount. | 10-06-2011 |
