Embodiment Construction

[0016] figure 1 is a block diagram of an embodiment obstacle detection system 100 using a single camera 106 . figure 1 The obstacle detection system 100 is implemented in a vehicle 102 moving in an indicated direction of movement on a road surface 110 . A camera 106 is located on the vehicle 102 to collect video images of the area 150 before the vehicle 102 moves over the area 150 . The vehicle 102 includes an obstacle detection function 104 configured to receive image data from the camera 106 and process the image data to determine whether an obstacle has been placed on the area 150 . figure 1 The embodiment obstacle detection system 100 is shown operating on a vehicle 102; however, the embodiment obstacle detection system 100 may be implemented in any type of structure where it is desired to detect obstacles in an area over which the structure is moving.

Abstract

Systems and methods for detecting obstacles using a single camera positioned on an apparatus in motion over an area of motion, or stationary over a moving area of motion. In an example method, a video stream of images is captured of the area of motion. The images in the video stream may be corrected for lens distortion prior to further processing. An Nth image frame is selected from a sequence of N images in the video stream. A set of N-1 difference images is calculated by subtracting each of the N-1 previous images from the Nth image. The N-1 difference images are added to one another to generate a combined difference image. A perspective transformation is performed on the combined difference image to generate a transformed image. The transformed image is analyzed to detect edges of obstacles in the transformed image. A signal indicating detection of an obstacle in the area of motion may then be generated.

Description

technical field [0001] The present invention relates to imaging systems in environments with moving structures, and more particularly, to imaging systems and methods for detecting obstacles. Background technique [0002] Imaging systems are used in moving structures such as vehicles and electric machines involved in navigation (eg, machine navigation or conveyance mechanisms) to detect obstacles that may prevent desired motion. Such imaging systems typically use one or more cameras aimed at the path of motion and an image processing system that analyzes the captured images to detect obstacles. When an obstacle is detected, an alert or other appropriate notification may be communicated to allow avoidance of the obstacle. Obstacle detection systems operate by detecting patterns in images that indicate obstacles. Obstacle detection can have difficulties when the structure is moving and adequate results often require the use of hardware and software equipment that can make obs...
