Abstract
A system for calibrating includes an input interface and a calibration parameter determiner. The input interface is configured to receive an image data of a calibrator in front of a camera unit. The camera unit is mounted inside a vehicle. The calibrator is mounted outside the vehicle. The calibration parameter determiner is configured to determine a calibration parameter based at least in part on the image data. The calibration parameter enables determination of an object proximity and a lane pattern.
Claims20
A system for calibrating, comprising:
- an input interface configured to receive an image data of a calibrator, wherein:
- the image data is captured by a camera unit,
- the camera unit is mounted inside a vehicle, and
- the calibrator is mounted outside the vehicle, wherein the calibrator includes at least one lane marker image;
- and
- a calibration parameter determiner configured to:
- identify a characteristic of a lane and a characteristic of a field of view of the vehicle based on the image data while the vehicle is in a non-driving state;
- and
- determine a calibration parameter based on the identified characteristics, wherein the calibration parameter improves accuracy of determination of an object proximity and a lane pattern compared with determination without the calibration parameter.
A method for calibrating, comprising:
- receiving an image data of a calibrator, wherein:
- the image data is captured by a camera unit,
- the camera unit is mounted inside a vehicle, and
- the calibrator is mounted outside the vehicle, wherein the calibrator includes at least one lane marker image, and
- identifying a characteristic of a lane and a characteristic of a field of view of the vehicle based on the image data while the vehicle is in a non-driving state;
- and
- determining, using a processor, a calibration parameter based on the identified characteristics, wherein the calibration parameter improves accuracy of determination of an object proximity and a lane pattern compared with determination without the calibration parameter.
A computer program product for calibrating, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
- receiving an image data of a calibrator, wherein the image data is captured by a camera unit is mounted inside a vehicle, and wherein the calibrator is mounted outside the vehicle and the calibrator includes at least one lane marker image;
- identifying, using a processor, a characteristic of a lane and a characteristic of a field of view of the vehicle based on the image data while the vehicle is in a non-driving state;
- and
- determining, using the processor, a calibration parameter based on the identified characteristics, wherein the calibration parameter improves accuracy of determination of an object proximity and a lane pattern compared with determination without the calibration parameter.
A calibrator for calibrating a driver assistance system, comprising:
- a mount;
- and
- an image coupled to the mount, wherein the mount mounts the image outside a vehicle and in front of a camera unit that is inside the vehicle, wherein the image includes a left side lane image and a right side lane image;
- wherein the calibrating the driver assistance system is based on a calibration parameter, and the calibration parameter:
- is determined, based on identifying a characteristic of a lane and a characteristic of a field of view of the vehicle based on the image, while the vehicle is in a non-driving state, and
- improves accuracy of determination of an object proximity and a lane pattern compared with determination without the calibration parameter.
