摘要： A method is provided for detecting road lane markers in a vehicle road using an imaging device. Road input data is captured using the imaging device. Lighting normalization is applied to the road input data. The method detects the road lane markers in a few main orientations in the normalized input data. In each main orientation, the normalized input data is convolved with an oriented edge detection filter for generating an oriented edge-based filter response. The normalized input data is convolved with an oriented line detection filter for generating an oriented line-based filter response. Candidate lane markers are selected in response to the edge-based filter response and line-based filter response in each main orientation. A transformation technique is applied to the candidate lane markers for identifying the lane markings in each main orientation.

摘要： A system and method that provide a video-based vehicle navigation system. The system positions an arrow on the video display that shows the specific turning direction for the vehicle for route guidance purposes. To determine the proper position of the guidance arrow, the process determines a distance from the current vehicle position to the location where the vehicle needs to turn using any suitable information, such as GPS position, range measurements and map information. The process then positions the guidance arrow on the ground at the turning location in world coordinates, and projects the guidance arrow onto the image. The camera can be calibrated to the ground using various techniques, such as an online automatic calibration process that uses detected objects in the scene around the vehicle.

摘要： A method is provided for detecting road lane markers using a light-based sensing device. Reflectivity data is captured using the light-based sensing device. A light intensity signal is generated based on the captured reflectivity data. The light intensity signal is convolved with a differential filter for generating a filter response that identifies a candidate lane marker region and ground segment regions juxtaposed on each side of the candidate lane marker region. A weighted standard deviation of the data points within the identified candidate lane marker region and weighted standard deviation of the data points within the ground segment regions are calculated. An objective value is determined as a function of the respective weighted standard deviations. The objective value is compared to a respective threshold for determining whether the identified candidate lane marker region is a lane marker.

摘要： 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.

摘要： A reconfigurable clear path detection system includes an image capture device and a primary clear path detection module for determining corresponding probability values of identified patches within a captured image representing a likelihood of whether a respective patch is a clear path of the road. A plurality of secondary clear path detection modules each are used to assist in identifying a respective clear path of the traveled road in the input image. One or more of the secondary clear path detection modules are selectively enabled for identifying the clear path. The selectively enabled secondary clear path detection modules are used to identify the clear path of the road of travel in the input image. A fusion module collectively analyzes the clear path detection results of the primary clear path detection module and the selectively enabled secondary clear path detection modules for identifying the clear path in the input image.

摘要： A method and system for vehicular clear path detection using adaptive machine learning techniques including reliable local model updating. Digital camera images are segmented into patches, from which characteristic features are extracted representing attributes such as color and texture. The patch features are analyzed by a Support Vector Machine (SVM) or other machine learning classifier, which has been previously trained to recognize clear path image regions. The SVM classifier is adaptively updated using reliable local test samples, such as positive clear path samples which just passed by the vehicle. The resultant classifier, being continuously and adaptively updated with recent, reliable training samples, exhibits improved performance and accuracy in analyzing subsequent image regions or patches for the existence of a clear driving path.
