Introduction

Andreas Haja is a notable inventor based in Hannover, Germany. He has made significant contributions to the field of automotive technology, particularly in camera systems and vehicle geometry. With a total of 3 patents, Haja's work reflects a commitment to enhancing vehicle safety and performance through innovative solutions.

Latest Patents

One of Haja's latest patents is a method and apparatus for calibrating a camera system of a motor vehicle. This invention involves determining calibration parameters such as rotation angle, pitch angle, yaw angle, roll angle, and the height of the camera above the road. The rotation angle is ascertained from the vanishing point derived from a first optical flow between two successive camera images. Additionally, the height of the camera is determined from a second optical flow between the same images. The method employs a regular grid placed over the first camera image to search for correspondences in the second image, allowing for accurate calibration.

Another significant patent by Haja is a method and measuring assembly for determining the wheel or axle geometry of a vehicle. This method includes illuminating a wheel region with both structured and unstructured light while the vehicle is in motion. Multiple images are captured to create a three-dimensional surface model, texture model, and motion model of the wheel region. The method calculates values for surface, texture, and motion parameters to minimize deviations from the acquired images, ultimately determining the rotation axis and center of the wheel.
