Patent number: 11846722Abstract: A method for improving an evaluation of object identification of a radar device of a motor vehicle. A first map is generated of the surroundings of said surroundings by a LiDAR scanner. A first object identification is performed on the basis of the generated first map of the surroundings by a first identification apparatus. A ground-truth model is created of the surroundings on the basis of the performed first object identification by the first identification apparatus. A second map is generated of the surroundings of the surroundings by the radar device. A second object identification is repeatedly performed using alternative object identification algorithms on the basis of the generated second map of the surroundings by a second identification apparatus of the radar device. A radar model is created of the surroundings on the basis of the repeatedly performed second object identification by means of the second identification apparatus.Type: GrantFiled: March 26, 2021Date of Patent: December 19, 2023Assignee: HELLA GmbH & Co.

Patent number: 11415690Abstract: A method is provided for operating a radar system of a vehicle. The radar system has at least one radar sensor for detecting at least one target outside the vehicle. A prediction of an ego-velocity (vEgo) of the vehicle is performed, so that a prediction result is determined. A classification for classifying the at least one detected target as a stationary target is then performed using the prediction result, so that a classification result is determined. One of at least two estimation methods is then selected for an estimation of the ego-velocity (vEgo), such that the selection is dependent on an evaluation of the classification result.Type: GrantFiled: August 28, 2017Date of Patent: August 16, 2022Assignee: Hella GmbH & Co.

Publication number: 20080043237Abstract: A device that automatically aligns laser beams to corresponding targets to establish a frame of reference for radiation oncology or diagnostic imaging. The device is comprised of one or more lasers and corresponding laser alignment targets, two motors for each laser to control its direction, a laser imaging device or devices, a wireline or wireless network, a computer for controlling each laser's motors, and a central computer connected to the laser imaging device(s). Each laser alignment target has crosshairs to align the laser beam to, and each laser alignment target also has unique identifying marks to distinguish it from the other lasers' targets. Each laser has two means for automatic alignment, one to adjust the laser beam positive or negative along X coordinates, and another to adjust the laser beam positive or negative along Y coordinates.Type: ApplicationFiled: August 2, 2007Publication date: February 21, 2008Inventors: Jimm Grimm, Christopher Grimm, James Grimm
