摘要： A local positioning device detects a local position of an automobile advancing along a lane formed on a road in a direction. A digital image data indicative of an advancing direction view observed from the automobile in the advancing direction is applied to the local position device. An edge extractor, a threshold generator, and a contour extractor are operable for extracting a contour data indicative of the lane from the image signal. A coordinate convertor converts the contour data into a plane view data indicating the dimensions of extracted contours correctly. A matching operator matches a line or an arc with each of extracted contour. A lane mark contour extractor selectively extracts a pair of extracted contours corresponding to the lane on which the automobile is located.

摘要： A parking assistance system is mounted in a vehicle, and has an image pick-up with a single camera, an image processing device, a display, a steering angle sensor, a wheel speed sensor, and a pulse counter. An A/D converter subjects two analog images picked up by the image pick-up at different locations to A/D conversion, and sends the results to frame memories. A CPU uses the digital image data and the transition data of the vehicle to calculate object data and a distance from the vehicle to the 3D object. An image thus obtained is then converted into a view from the above. The view from the above is stored in a frame memory, and outputted to the display under the control of a controller for display.

摘要： In a rendering device, a processor derives an estimated path to be traced by the left- and right-rear wheels of a vehicle based on a rudder angle that is provided by a rudder angle sensor. The processor then determines positions for overlaying indicators on the derived estimated path. The processor then renders the indicators on the determined points in a captured image which is provided by an image capture device, and generates a display image. In the display image, the indicators move along the estimated path in the direction the vehicle is heading towards. In this manner, the estimated path in the display image that is generated by the rendering device becomes noticeable for a driver of the vehicle.

摘要： In a rendering device 10, ROM 4 stores a vehicle model. A rudder angle sensor 3 detects a rudder angle of the vehicle, and based thereon, CPU 6 calculates an estimated path for the vehicle. The CPU 6 receives captured images from cameras 21 to 2N. The CPU 6 generates a display image based on those captured images, the estimated path, and the vehicle model. This display image includes the vehicle model arranged on the estimated path, and displayed on a display device 8 placed in the vehicle. In this manner, the display image generated by the rendering device 10 is indicative and helpful for a driver of the vehicle to exactly figure out a parking space available for the vehicle.

摘要： An apparatus and method for correctly determining the position of a vehicle in a traffic lane by obtaining correct information about the position of the traffic lane without being affected by variations in the road surface, weather, time of day, or such imaging conditions as fixed or moving lighting, are provided. An edge signal of a high spatial frequency component and a luminance signal of a low spatial frequency component of a digital image signal representing the view of the local area to the front of a vehicle are extracted. A road contour signal is then extracted from the edge signal, and a road region signal is extracted from the luminance signal. The position of the lane Sre is then detected with high precision by evaluating the lane contour Sre based on the road region signal Srr and lane contour data Sre.

摘要： In a rendering device Urnd1, a CPU 7 receives a captured image each from two image capture devices 1 and 2. The CPU 7 then receives a steering angle of a steering wheel of a vehicle from a steering angle sensor 3. Based on the steering angle, the CPU 7 derives an estimated trajectory for the vehicle to take in the course of time. Then, with reference to the estimated trajectory, the CPU 7 selects several pixels each from the captured images, and then generates a drive assistant image based on those pixels. In this manner, the drive assistant image generated by the rendering device Urnd1 hardly causes the driver to feel strange.

摘要： An image processor has two types of image pickup devices connected thereto. One image pickup device shoots the state of the surroundings of a vehicle, and the other shoots the state of the inside of the vehicle. A processor uses images from the image pickup devices to generate a driving assist image representing both of the state of the surroundings of the vehicle and the state of the inside thereof. With this, it is possible to provide an image processor which generates a driving assist image capable of providing more information to a driver.

摘要： In an image processing apparatus carried on a vehicle, an image of a scene around the vehicle, which is photographed by an image pick-up, is inputted into a white line failure extractor. Then, outline points of a white line on a road and a guardrail, which is parallel to the white line, are sought. Further, the outline points are detected as a polynomial. Moreover, the image photographed by the image pick-up is also inputted into an intermittent image obtainer. Then, the images from the image pick-up are intermittently obtained at constant periodical intervals, and further the images are compressed using JPEG compression method. Further, in a synthesizer, the feature data from the white line feature extractor and the image data from the intermittent image obtainer are aligned in order of time. Moreover, the image data and feature data, which are aligned in order of time, are conserved within a given constant period by a recorder. Thus, accurate data as to condition of the road can be recorded using a small capacity memory.
