  • Patent number: 7636479
    Abstract: A system for classifying image data includes a vision system (58) for continuously imaging an area (42) of interest and providing an image signals. A classifier (84) determines an image class corresponding to each image signal, determines a confidence level for each determined image class, determines a time period for the confidence level, and establishes an image classification in response thereto. Switching between image classifications is in response to the confidence level and time period of the confidence level. When used in a vehicle restraining system (20), other monitor vehicle parameters (54) can be used to adjust the confidence levels and time periods needed to switch between image classifications.

  • Patent number: 7471832
    Abstract: A system (400) for classifying an input image into one of a plurality of output classes includes a plurality of pattern recognition classifiers (420, 422, 424). Each of the plurality of pattern recognition classifiers determines a candidate output class and at least one rejected output class for the input image from an associated subset of the plurality of output classes. Each classifier generates a confidence value associated with the classifier based on the determination. An arbitrator (430) selects a classifier having the best associated confidence value and eliminates the at least one rejected class determined at the selected classifier from consideration as the associated class for the input image.

  • Patent number: 7379559
    Abstract: An apparatus (20) for determining a location of a person's head (90) includes stereo vision system (60) for imaging an area of interest such as the interior of a vehicle (26). The vision system provides an image signal of the area of interest. An analyzer (80) analyzes the image signal to identify head candidates (90?, 210, 212, 214, 216) in the area of interest and provides data regarding any identified head candidates in the area of interest. A processor (80) processes the provided data regarding identified head candidates to locate the person's head. In an air bag restraining system (22), a controller (50) monitors the location of the person's head and controls an air bag (34) in response to a sensed crash condition (52) and the location of the person's head.

  • Patent number: 7123747
    Abstract: A method for helping to control a vehicle occupant protection device (22) includes taking an image of the vehicle interior with a digital imager (50) having an array of pixels (53). A contiguous portion of the image less than the entire image is selected. At least one image enhancement technique is applied to the selected image portion. The enhanced image portion is combined with the other portions of the image to make an enhanced image. The enhanced image is analyzed to detect at least one of features and characteristics of the enhanced image. Alternatively, a selected non-contiguous group of the pixels (53) of the imager (50) are read out, as representative of the entire image, to estimate the illumination levels across the entire array of pixels. In one aspect, the imager shutter (56) speed may be controlled to enhance the image.

  • Patent number: 7003384
    Abstract: A method and apparatus (20) for recognizing and determining a location of an object (40) in an area of interest (31) comprises an imaging device (61) for obtaining an image of the area of interest. At least three identifying marks (104) are located at predetermined positions in the area of interest (31). The apparatus (20) also comprises a memory (78) in which the predetermined positions of the at least three identifying marks (104) are stored. A controller (80) determines whether the imaging device (61) is calibrated properly by analyzing the image obtained by the imaging device to determine whether positions of the at least three identifying marks (104) in the obtained image correspond to the predetermined positions stored in the memory (78). The controller (80) is also adapted to determine whether a view of the area of interest (31) from the imaging device (61) is obstructed.

  • Patent number: 6947575
    Abstract: An apparatus (30) and associated method determine a vehicle occupant characteristic. An imager (32) collects a first image of an occupant location while the occupant location is subject to a first lighting condition. A light source (38) provides light onto the occupant location. The imager (32) collects a second image of the occupant location while the occupant location is subject to the first lighting condition and the provided light. A subtractor device (50) generates a third image of the occupant location indicative of the difference between the first and second images. An image processing device (52) processes the third image to determine the vehicle occupant characteristic.

  • Publication number: 20050196015
    Abstract: An apparatus (100) for tracking at least one head candidate comprises an image analyzer (104) for analyzing an image signal to identify at least one of a possible plurality of new head candidates within an area of interest. The image analyzer (104) provides data regarding the identified head candidates. A tracking system (108) stores location information for at least one tracked head candidate. A candidate matcher (106) predicts the current position of a given tracked head candidate and selects a subset of the at least one of a plurality of new head candidates according to their distance from the predicted position. The similarity of each member of the selected subset to the tracked candidate is evaluated to determine if a member of the selected subset represents a current position of the tracked candidate.

  • Patent number: 6914526
    Abstract: A vehicle intrusion detection system (10) for detecting an intrusion condition of a vehicle (12) having an occupant compartment (14) partially defined by an outer structure (30) of the vehicle, comprises an actuatable illuminator (40) mounted in the vehicle and having a limited field of illumination (52) extending within the vehicle occupant compartment adjacent the vehicle outer structure. A linear imager (60) mounted in the vehicle (12) has a field of view (62) that substantially coincides with the field of illumination (52) of the illuminator (40). A controller (70) compares a first image taken by the imager (60) when the illuminator (40) is actuated and a second image taken by the imager when the illuminator is unactuated to help determine the existence of an intrusion condition of the vehicle.

  • Patent number: 6810133
    Abstract: An occupant sensing system (12) and an associated method provide for the sensing of an occupant (14). An illuminating element (46) of the system (12)selectively illuminates the interior of a vehicle (8). An image sensor (50) acquires a first image of the interior of the vehicle (8) when the interior of the vehicle is illuminated by ambient sources only and acquires a second image of the interior of the vehicle when the interior of the vehicle is illuminated by ambient sources and the illuminating element (46). A controller (34) removes the effect of ambient sources by comparing the first and second images to produce a third image of the interior of the vehicle (8) as illuminated by the illuminating element (46) only. The controller (34) determines the presence of an occupant (14) by comparing the third image to a produced map of the interior of the vehicle (8).

  • Patent number: 6781676
    Abstract: An apparatus (12) for determining the location of a vehicle occupant (20) in a vehicle interior includes a light source (40) for projecting at least one structured light beam (42) onto an area of interest (44) to form a light pattern on the area of interest. A beam divergence control device (50) alters the apparent location of the light source (40) with respect to the area of interest (44). An imager (60) detects the light reflected from the area of interest (44). A characteristic of the reflected light is measured, and the distance between the imager (60) and the area of interest (44) is measured, based on the measured characteristic of the reflected light.
