Object detection and ranging method
First Claim
Patent Images
1. An object detection and ranging method for a motor vehicle, comprising the steps of:
- providing an imaging device;
providing a data processor for interpreting a captured image of a field of interest provided by the imaging device;
processing rows of pixels;
comparing pixel data collected by said data processor to a pixel map of one or more surfaces to filter out and discard said surfaces; and
reporting a real world translation to a vehicle operator, wherein said real world translation includes at least object dimensions and distance from the vehicle for all objects in said field of interest;
wherein processing said rows further comprises a morphological erosion filter for filtering out and discarding pixel noise.

Abstract
The present invention relates to a method for object detection and ranging within a vehicles rearward field of interest which includes an algorithm to translate images provided by an imaging device. An image device provides images to a processor which divides the images into groups of rows of pixels. The rows are processed by the algorithm which includes assigning each pixel in the rows to an object. The translation of the image from outside of the vehicle is provided to the vehicle operator and includes the tracking of location and dimensions of multiple objects within the viewing range.

8. An object detection and ranging method for a motor vehicle, comprising the steps of:
-
providing an imaging device to selectively capture an image of a field of interest; providing a data processor to operably collect a frame of said captured image; breaking data from said collected frame into groups of rows of pixels; processing said rows of pixels to operably assign each respective pixel in a row to one or more objects in the field of interest until every row of pixels is processed; generating a real world translation of said one or more objects; and reporting said real world translation to a vehicle operator, wherein said real world translation includes at least object dimensions and distance from the vehicle for all objects in said field of interest; wherein processing said rows further comprises a morphological erosion filter for filtering out and discarding pixel noise. - View Dependent Claims (9, 10, 11, 12, 13, 14, 18)

15. An object detection and ranging method for a motor vehicle, comprising the steps of:
-
providing an imaging device to selectively capture an image of a field of interest; providing a data processor to operably collect a frame of said captured image; breaking data from said collected frame into groups of rows of pixels; processing said rows of pixels to operably assign each respective pixel in a row to one or more objects in the field of interest until every row of pixels is processed, wherein said processing said rows includes comparing pixel data collected by said data processor to a pixel map of one or more surfaces to filter out and discard said surfaces; merging objects determined to be in such proximity with one another as to be part of the same object generating a real world translation of said one or more objects; and reporting said real world translation to a vehicle operator, wherein said real world translation includes at least object dimensions and distance from the vehicle for all objects in said field of interest, wherein processing said rows further comprises a morphological erosion filter for filtering out and discarding pixel noise. - View Dependent Claims (16, 17, 19)
