Method and device for determining a calibrating parameter of a stereo camera
First Claim
1. A method for determining an object property of an object with the aid of images that have been recorded with the aid of a camera, the method comprising the steps of:
- defining at least one object in a first image recorded with the aid of the camera,determining the brightness of the defined object,recording a further image at least each time after a preset time interval with the aid of the camera,defining the object in each of the further images,determining each time, the brightness of the defined object of each image,assigning an object property to the object dependent on a curve defined by the brightness, andwherein an actual brightness of the object is changed with a first frequency which differs from the sampling rate defined by the time interval between two images.

Abstract
The invention relates to a method and a device for determining an object property of an object with the aid of images that have been recorded with the aid of a camera. Further, the invention relates to a method for determining a calibration parameter for a stereo camera. For determining the object property of an object, the object is defined in a first image recorded with the aid of the camera. Further, the brightness of a defined object is determined. Each time after a preset time interval, a further image is recorded with the aid of the camera. The object is defined in each of the further images and each time, the brightness of the defined object of each image is determined. Dependent on the brightness curve, an object property is assigned to the object.

13. A device for determining an object property of an object with the aid of images that have been recorded with the aid of a camera, comprising:
-
a camera which at least at a preset time interval records images of at least one object, means for defining at least one object in a first image recorded with the aid of the camera, means for determining a brightness of the defined object, means for defining the object in each of the further images recorded with the aid of the camera at the preset time interval, means for each time, determining the brightness of the defined object of each image, means for assigning an object property to the object dependent on the brightness curve, and means for determining an actual brightness of the object with a first frequency which differs from the sampling rate defined by the time interval between two images. - View Dependent Claims (14, 15)
