20100165104 | Drive Assistance Device - A drive assistance device has an imaging device ( | 07-01-2010 |
20100245579 | IMAGE PROCESSING DEVICE AND METHOD, DRIVING ASSIST SYSTEM, AND VEHICLE - A camera is fixed in the mirror case of a door mirror downwardly in such a way that the front-rear wheels of a vehicle and the bottom edges of the sides of the vehicle (bottom portion) fit in view regardless of the state in which the door mirror is placed. The lower ends of the sides of the vehicle on a distortion corrected image is detected and a direction ( | 09-30-2010 |
20110001826 | IMAGE PROCESSING DEVICE AND METHOD, DRIVING SUPPORT SYSTEM, AND VEHICLE - A driving support system performs a viewpoint conversion, generates, from a camera image obtained from an in-vehicle camera, an extended bird's-eye view image corresponding to a synthesized image of first and second element images, and displays the generated image. The first element image is a bird's-eye view image showing the condition around a vehicle. The second element image is a far image showing the condition far away from the vehicle. The extended bird's-eye view image is obtained by converting the camera image to an image viewed from the viewpoint of a virtual camera. When the first and second element images are generated, the depression angles of the virtual camera are 90 degrees and 90 degrees or less, respectively. When the extended bird's-eye view image is generated corresponding to the tilt angle or the like of an actual camera, it is automatically determined whether the lack of an image occurs or not. In the case where the lack of the image occurs, the position of the boundary between the first and second element images, the height of the viewpoint of the virtual camera, etc., are adjusted so that the lack disappears. | 01-06-2011 |
20110013021 | IMAGE PROCESSING DEVICE AND METHOD, DRIVING SUPPORT SYSTEM, AND VEHICLE - While extracting four feature points from a camera image obtained from a camera installed in a vehicle, an image processing device sets the positions of four reference points on an offset correction image to be generated from the camera image and performs a coordinate conversion based on a homography matrix so that the coordinate values of the four feature points are converted to the coordinate values of the four reference points. The image processing device sets each of the coordinate values so that an image center line and a vehicle center line are matched with each other on the offset correction image. The image processing device determines whether or not an image lacking area in which image data based on the image data of the camera image is not present is included within the entire area of the generated offset correction image. If the image lacking area is included, the two reference points or the four reference points are symmetrically moved in the left and right directions and the homography matrix is recalculated according to the positions of the reference points after the movement. | 01-20-2011 |

20100271481 | Maneuver Assisting Apparatus - A maneuver assisting apparatus is arranged on a vehicle that moves on a road surface, and includes a plurality of cameras that capture the road surface from diagonally above. A CPU repeatedly creates a complete-surround birds-eye view image relative to a road surface, based on a plurality of object scene images repeatedly outputted from the plurality of cameras. The created complete-surround bird's-eye view image is reproduced on a monitor screen. The CPU determines whether or not there is a three-dimensional object such as an architectural structure in a side portion of a direction orthogonal to a moving direction of the vehicle, based on the complete-surround bird's-eye view image created as described above. Also, the CPU adjusts a ratio of a partial image equivalent to a side portion noticed for a determining process, to the complete-surround bird's-eye view image reproduced on the monitor screen, based on a determination result. | 10-28-2010 |
20110181714 | CONGESTION DEGREE MEASURING APPARATUS - A congestion degree measuring apparatus includes a reproducer. A reproducer reproduces a reference image representing a state in which a plane is overlooked. A taker repeatedly takes a scene image outputted from a camera having an imaging surface that captures the plane. An allocator allocates one or at least two second areas respectively corresponding to one or at least two first areas designated on the reference image reproduced by the reproducer to the scene image taken by the taker. A measurer executes a process of measuring a congestion degree of one or at least two dynamic objects existing on the plane at each second area allocated by the allocator, based on the scene image taken by the taker. | 07-28-2011 |

20080198229 | VEHICLE OPERATION SUPPORT SYSTEM AND VEHICLE INCLUDING SYSTEM - A vehicle operation support system is provided in which a captured image or a guide displayed on a display device can be adjusted easily by a simple operation. In adjusting misalignment between the image and the guide displayed as an oblique captured image on the display device, the user converts the displayed image and guide to a so-called high-angle display (which is displayed as if looked down directly from the above), and the converted high-angle image is then corrected or adjusted so that the image and the guide are displayed in correct alignment as desired. | 08-21-2008 |
20080205706 | APPARATUS AND METHOD FOR MONITORING A VEHICLE'S SURROUNDINGS - A vehicle surroundings monitoring apparatus has: a point-of-view converter that converts an image shot with a camera installed on a vehicle into a bird's-eye-view image through point-of-view conversion; a position adjuster that performs position adjustment between two bird's-eye-view images produced from two images shot at different time points, the position adjuster performing the position adjustment based on the two bird's-eye-view images; and a three-dimensional object detector that detects a three-dimensional object around the vehicle based on differences between the two bird's-eye-view images having undergone the position adjustment. | 08-28-2008 |
20080309763 | Driving Support System And Vehicle - Disclosed is a driving support system. With this system, a vehicle including a camera installed thereon is arranged at the center of a parking lot defined by two parallel white lines. End points of the respective white lines are included in the field of view of the camera. While the vehicle is moving forward, first and second editing images are obtained respectively at first and second points different from each other. Two end points of each of the editing images are detected as four feature points in total. Image transformation parameters for causing the center line of the vehicle and the center line of the image to coincide with each other are found on the basis of coordinate values of the four feature points on each of the editing images. An output image is obtained by use of the found image transformation parameters. | 12-18-2008 |

20110169954 | MANEUVERING ASSISTING APPARATUS - A laser irradiator L_N (N: 1 to 4) is arranged in an automobile and radiates a laser beam obliquely downward. A camera C_N arranged on the automobile has a viewing field VW_N corresponding to a radiating direction of the laser irradiator L_N. A CPU determines whether or not a change amount of a reflection position of the laser beam radiated by the laser irradiator L_N exceeds a reference, based on output of the camera C_N. The radiating direction of the laser irradiator L_N is changed by the CPU when a determined result is updated from a negative result to a positive result. A manner of changing in the reflection position of the laser beam radiated by the laser irradiator L_N is detected by the CPU based on the output of the camera C_N parallel to a changing process for the radiating direction. The CPU outputs a different notification corresponding to the detected result toward a driver of the automobile. | 07-14-2011 |
