20130027196 | OBSTACLE DETECTION SYSTEM - A computer-implemented method of detecting objects in a path of a vehicle is provided. An image frame that depicts the path of the vehicle is obtained. An edge-image corresponding to the image frame is generated. A binary image corresponding to the edge-image is also generated. One or more blobs in the binary image that respectively correspond to one or more objects in the image frame are identified. Based on an analysis of the blobs in the binary image, a determination is made that one of the objects in the image frame is an obstacle in the path of the vehicle. | 01-31-2013 |
20130070095 | FAST OBSTACLE DETECTION - 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. | 03-21-2013 |
20130070962 | EGOMOTION ESTIMATION SYSTEM AND METHOD - A computer-implemented method for determining an egomotion parameter using an egomotion estimation system is provided. First and second image frames are obtained. A first portion of the first image frame and a second portion of the second image frame are selected to respectively obtain a first sub-image and a second sub-image. A transformation is performed on each of the first sub-image and the second sub-image to respectively obtain a first perspective image and a second perspective image. The second perspective image is iteratively adjusted to obtain multiple adjusted perspective images. Multiple difference values are determined that respectively correspond to the respective difference between the first perspective image and the adjusted perspective images. A translation vector for an ego motion parameter is determined. The translation vector corresponds to one of the multiple difference values. | 03-21-2013 |
20130162826 | METHOD OF DETECTING AN OBSTACLE AND DRIVER ASSIST SYSTEM - To detect an obstacle in a single image captured using a single image sensor of a driver assist system, at least one image feature is established in the single image which extends along a line passing through a projection point of the image sensor. At least one line extending along a direction normal to a road surface in the world coordinate system is thereby identified based on the single image, which is used as a signature for an obstacle. | 06-27-2013 |
20130293678 | VIRTUAL NAVIGATION SYSTEM FOR VIDEO - System and method for adjusting the parameters of an image capturing device, such as a camera that captures a sequence of images and generates another image from the captured sequence of images using parameters that identify a virtual location and overlaying the generated image with a 3D generated image where distortion compensation has occurred been applied to the image. | 11-07-2013 |
20130293683 | SYSTEM AND METHOD OF INTERACTIVELY CONTROLLING A VIRTUAL CAMERA - A multiple-view virtual camera system comprising one or more image source units, an image processing unit, a parameter setting unit in signal communication with the image processing unit, and a display in signal communication with the image processing unit. The display is configured to display images generated by the image processing unit to a user of the virtual camera system, where the displayed images are configured according to image-related parameters input by a user of the multiple-view camera system through the parameter setting unit. The parameter setting unit may include a user interface, such as a single-touch or multi-touch touchscreen display, configured to accept input from the user that adjusts the parameters that are transmitted to the image processing unit and utilized by the image processing unit. A method of interactively controlling the virtual camera system by a user of a motor vehicle is also disclosed. | 11-07-2013 |
20150294167 | METHOD AND SYSTEM FOR DETECTING TRAFFIC LIGHTS - A method for detecting traffic lights is provided. The method includes: obtaining a color image captured by a camera; converting the color image into a first monochrome scale image; converting the first monochrome scale image into a first binary image; identifying a first set of candidate blobs in the first binary image based on at least one predetermined geometric parameter; and determine whether a first region in the color image, which first region corresponds to one of the first set of candidate blobs, is a green traffic light using a green traffic light classifier. The accuracy and efficiency may be improved. | 10-15-2015 |
20150332089 | SYSTEM AND METHOD FOR DETECTING PEDESTRIANS USING A SINGLE NORMAL CAMERA - The present application provides pedestrian detection system and method. A pedestrian detection method includes: obtaining an image captured by a camera; identifying a pedestrian candidate in the image; transforming the image into a top view image; calculating the actual height of the pedestrian candidate based on the top view image and extrinsic parameters of the camera; and determining whether the pedestrian candidate is a true positive by determining whether the actual height of the pedestrian candidate is within a predetermined pedestrian height range. The system and method of the present application have lower cost and higher accuracy compared with conventional technologies. | 11-19-2015 |
20150334301 | SYSTEM AND METHOD FOR GENERATING A SURROUND VIEW - A method and system for generating a surround view are provided. The method may include: establishing a surround surface; obtaining a plurality of images of surroundings; and projecting the images onto the surround surface based on a projection relationship between points on the surround surface and pixels on the images to generate a surround view, where the projection relationship may change with heights of the points on the surround surface. An improved projection effect may be obtained. | 11-19-2015 |
