摘要： An image based obstacle detection method. A camera mounted on a vehicle provides a set of image frames whilst the vehicle is in motion. The image frames define an image plane having a vertical aspect and a horizontal aspect. The relevancy of an object is determined by (i) selecting first and second feature points from the object that are spaced apart vertically in a first image frame; (ii) tracking the positions of the first and second feature points over at least a second image frame; and (iii) deciding the object to be relevant if the first and second feature points move dissimilar distances in physical space, within a tolerance, and deciding the object to be irrelevant otherwise. The motion of relevant objects is then estimated to determine if any relevant object is likely to become an obstacle to the vehicle.

摘要： A combination measuring tape/chalk marker holder includes a main housing and a chalk retention pocket. The main housing has a main housing shell with a base and a back plate. The main housing is an equilateral triangular prismatic body with two outwardly curved lateral walls meeting at an apex. Within the housing, a locking reel holding a flexible measuring tape is releasably engaged with a locking hub formed on the back plate. The measuring tape extends through a portal formed in one of the outwardly curved lateral walls. The chalk retention pocket is fixed to and extends from the back plate. The pocket has a base parallel to and coextensive with the main housing base, two parallel lateral walls, and a flexible chalk retention member. The chalk retention pocket is flexible and removably retains a convex lensate marking body. A rotatable foot enables the holder to stand erect.

摘要： A bead crimping tool for crimping a bead element and method for use, wherein the tool includes a base handle, a crush plate member, a pair of opposed pincer members, an actuator handle, and a crush arm member. The bead element is placed on the crush plate and preferably secured in place by the crush arm. Crimping the bead includes squeezing of the actuator handle. During a first portion of such actuation, a cam portion of the actuator handle cases the pincer members to impart a lateral compressive force to a lateral portion of the bead element sufficient to collapse the bead element in a lateral direction. During a subsequent second portion of the single actuation cycle, the crush arm is caused to impart a longitudinal compressive force about a top portion of the bead element sufficient to compress the collapsed bead element in a longitudinal direction.

摘要： A method of dynamically calibrating a given camera relative to a reference camera of a vehicle includes identifying an overlapping region in an image frame provided by the given camera and an image frame provided by the reference camera and selecting at least a portion of an object in the overlapped region of the reference image frame. Expected pixel positions of the selected object portion in the given image frame is determined based on the location of the selected object portion in the reference image frame, and pixel positions of the selected object portion are located as detected in the given image frame. An alignment of the given camera is determined based on a comparison of the pixel positions of the selected object portion in the given image frame to the expected pixel positions of the selected object portion in the given image frame.

摘要： A vehicle interior classification system and method in accordance with the present invention determines a classification relating to the interior of the vehicle, such as the occupancy status of a vehicle seat or the state of alertness of a vehicle driver, from one or more images of an appropriate portion of the interior of the vehicle acquired with an image capture device. The acquired images are preferably processed to limit the dynamic range of the images to obtain a resultant image which can comprise one or more regions of interest which are less than the total field of view of the image capture device. The resultant images are processed to extract information about features in the image and, in one embodiment, this processing is achieved with a two-dimensional complex discrete wavelet transform which produces a set of coefficients corresponding to the presence and/or location of the features in the resultant image. The set of coefficients produced with such a transform is potentially quite large and can be reduced, through described techniques, to a subset of the total number of coefficients, the members of the subset being selected for their ability to discriminate between the classifications defined for the system. By selecting a subset of the possible coefficients, computational requirements are reduced, as are hardware requirements in the system, such as memory. The selected set of coefficients (whether comprising all of the coefficients or a subset thereof) are provided to a classifier which processes the coefficients with a set of calibration vectors, that were determined when the system was calibrated, to determine the most probable classification for the portion of the vehicle interior.

摘要： A method of dynamically ascertaining the alignment of a vehicular camera. The method involves acquiring a sequence of images provided by the camera whilst the vehicle is in motion. For each range of steering angles, the method (i) selects a plurality of feature points in the images, (ii) tracks a motion trajectory for each selected feature point, and (iii) determines a vanishing point in the image plane based on the tracked motion trajectories. The method determines a vanishing line in the image plane based on a locus of these vanishing points and determines the alignment of the camera based on the position of a central vanishing point (corresponding to the zero degree angle) and the vanishing line.
