    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: 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 a rendering device Urnd, a CPU generates a lower viewpoint image based on captured images captured by image capture devices both securely mounted to a vehicle. Here, the lower viewpoint image shows a region rear of the vehicle viewed from those image capture devices. Then, the CPU executes viewpoint conversion processing onto the captured images, and generates an upper viewpoint image. Here, the upper viewpoint image shows also the region rear of the vehicle but viewed from a camera virtually placed above the vehicle. The CPU then stitches the upper and lower viewpoint images together to generate a drive assistant image. In such manner, the drive assistant image generated by the rendering device Urnd becomes informative enough for a driver of the vehicle.

    摘要: In a rendering device, a processor receives surrounding images from image capture devices placed in a vehicle, and based thereon, generates a vehicle overlaid image. The processor also receives a rudder angle &thgr; from a rudder angle sensor placed in the vehicle. Then, based on the received rudder angle &thgr;, the processor calculates a 3D predictive trajectory of the vehicle, and on the vehicle overlaid image, renders the calculated 3D predictive trajectories thereby generating a display image. Therefore, the display image generated by the rendering device is driver-friendly.

    摘要: In a rendering device Urnd1, a processor 1 receives a front-left image Sfl and a front-right image Sfr at regular intervals, and therefrom, cuts out a partial front-left image and a partial front-right image for overlay onto a mask image. The processor 1 then overlays, with a predetermined timing, any one of vehicle model images varying in size onto the mask image. Here, the vehicle model image is overlaid in such manner as to create a moving picture as if the vehicle model image is moving forward. With such vehicle model image, a driver of a vehicle can instantaneously recognize that a drive assistant device is now showing the front side of the vehicle.

    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.
