摘要： A method of exposure control for an imaging system. A predetermined number of images are captured by one or more imagers, wherein the images are defined by an image resolution matrix. The images are masked to establish a region of interest within the image resolution matrix and brightness of the images is analyzed within the region of interest. An exposure time is calculated for a subsequent image capturing step based on the brightness analysis, and an exposure time setting of the imager(s) is adjusted during the subsequent image capturing step based on the calculated exposure time.

摘要： A technique for identifying beam images of a beam matrix includes a number of steps. Initially, a plurality of light beams of a beam matrix, which are arranged in rows and columns, are received after reflection from a surface of a target. Next, a reference light beam is located in the beam matrix. Then, a row pivot beam is located in the beam matrix based on the reference beam. Next, remaining reference row beams of a reference row that includes the row pivot beam and the reference beam are located. Then, a column pivot beam in the beam matrix is located based on the reference beam. Next, remaining reference column beams of a reference column that includes the column pivot beam and the reference beam are located. Finally, remaining ones of the light beams in the beam matrix are located.

摘要： A photoelectric sensor is provided with the capability of calculating a threshold magnitude based on a maximum light intensity received by a light sensitive device. The maximum value of the light intensity is determined during a preselected period of time when no object is blocking the path of a light beam. A second threshold magnitude is used to assist the present invention in determining the leading edge and trailing edge of a transparent object. The values of the first and second threshold magnitudes are updated dynamically as bottles pass through the path of the light beam. This permits the photoelectric sensor to react to changes in light intensity without providing false signals of bottles within the light path or missing bottles that are within the light path.

摘要： A method of classifying vehicle occupants utilizes a neural network engine having a state machine for determining if an occupant has changed preferably between an adult and adult, an adult and child, and a child and child from a pair of images. If no change has occurred, the method utilizes the prior occupant type and then decides if the occupant has changed in position. If no, the occupant is deemed static and the prior type is valid as a classification or output to preferably a vehicle restraint system. If the occupant has changed in position, a dynamic classification process is initiated by either an adult or a child dynamic classifier as dictated by the state machine. Valid dynamic classifier outputs or classifications can be sent to the restraint system and invalid dynamic classifier outputs are sent to a static classifier for update of the occupant type.

摘要： A vision-based occupant classification method utilizes a static classification routine for achieving highly accurate occupant classification, a dynamic detection routine for quickly responding to changes in occupant position, and a category state change routine for detecting potential changes in occupant category. The static classification routine determines an initial classification of the occupant, after which the dynamic detection routine monitors for changes in occupant position and the category state change routine monitors for a potential change in occupant category. If category state change routine detects a potential change in occupant category, the static classification routine is re-executed to re-classify the occupant. The category state change routine identifies a composite optical flow vector associated with occupant movement, and detects a potential change in occupant category when the composite flow vector crosses one or more pre-defined entry/exit motion gates.

摘要： Electromagnetic radiation is directed from an optical grating in a regular array of beams in rows and columns toward a target object surface; and the reflected beams are focused through a lens to form beam images on an image plane of a single camera. Each of the beam images has a position on the image plane that moves substantially linearly with variation of a target distance between the optical grating and a point on the object surface from which that beam image is reflected; and the direction of the substantially linear movement of each beam image forms a predetermined angle with the column of the array of beam images on the image plane to which that beam belongs at a common target distance. Positional data for each of the beam images on the image plane is derived and provided to a processor which uses stored reference data defining predetermined beam paths in the image plane for the beam images to locate and determine the associated one of the predetermined beam paths for each of the beam images on the image plane, determine the location of each of the beam images along its associated predetermined beam path, determine the target distance for that beam and store an array of the determined target distances for each of the located beam images to characterize the object surface. The predetermined angle may provide for each beam having a separate predetermined beam path. For greater resolution, some of the beam paths may have two associated beams, and processing is provided to distinguish the beams on a single beam path uniquely.
