First Claim
Patent Images
1. An object detection system for detecting objects within a region of interest, comprising:
- a camera configured to image a region of interest;
a structured light source configured to provide a substantially two-dimensional light curtain within a field of view of the camera formed by at least one projected laser beam at a wavelength detectable by the camera; and
an image analysis component configured to detect objects within the region of interest from at least a position of the at least one projected laser beam within the image.

Abstract
Systems and methods are provided for imaging a region of interest. A structured light source is configured to provide a substantially two-dimensional light curtain within a field of view of the camera formed by at least one projected laser beam at a wavelength detectable by the camera. An image analysis component is configured to detect objects within the region of interest from at least a position of the at least one projected laser beam within the image.

12. A method for detecting objects within a region of interest, comprising:
-
projecting a substantially two-dimensional light curtain into a region of interest; imaging the region of interest at a camera to provide an image, such that an intersection of the substantially two-dimensional light curtain with the ground is visible; and determining that an object is present if the intersection of the substantially two-dimensional light curtain with the ground deviates from an expected baseline. - View Dependent Claims (13, 14, 15, 16, 17)

18. An object detection system for detecting objects within one of a blind spot and a region rearward of a vehicle, comprising:
-
a camera configured to image the one of the blind spot and the region rearward of the vehicle; a structured light source, comprising a laser diode and a beam shaping optical component, configured to provide a substantially two-dimensional light curtain within a field of view of the camera formed by at least one projected laser beam at a wavelength detectable by the camera; and an image analysis component configured to detect objects within the one of the blind spot and the region rearward of the vehicle from at least a position of the at least one projected laser beam within the image. - View Dependent Claims (19, 20)
