  • Publication number: 20240134049
    Abstract: A method for recognizing a traffic sign by means of a LiDAR system. The LiDAR system is designed to sense an intensity level of a light signal detected in the LiDAR system, the light signal including a plurality of light signal points. The method includes the following steps: a) ascertaining a degree of reflection of each light signal data point from the intensity level thereof; b) comparing the ascertained degrees of reflection with a predefined reflectivity limit value; c) if the predefined reflectivity limit value is exceeded, marking the corresponding light signal data point as belonging to a retroreflector; d) ascertaining a size of the retroreflector from the marked light signal data points. e) recognizing the retroreflector as a traffic sign as a function of the ascertained size of the retroreflector.

  • Publication number: 20240094352
    Abstract: A lidar device having a light source, a detector, and a mirror device. The light source has a main radiation direction and the detector has a main detection direction. The mirror device is rotatable about an axis and has a facet wheel with a number of facets. The main radiation direction and the main detection direction stand at a predetermined angle to each other, the predetermined angle being a function of the number of facets. A light beam emitted from the light source is reflected by a first facet and a light beam reflected back from an object is reflected by a second facet. Here the first facet and the second facet are different.

  • Publication number: 20220179077
    Abstract: A method for the supplementary detection of objects by a LIDAR system. The LIDAR system is configured to scan a solid angle range to carry out a primary distance determination method for surroundings objects. An emitter unit emits at least one laser beam in a solid angle strip of the solid angle range, laser light reflected from surroundings objects being received by a detector unit to ascertain the distance and the position of surroundings objects with the aid of the primary distance determination method. The method includes: scanning the entire solid angle range and subsequently generating a two-dimensional intensity distribution of the detected signal light. This is followed by generating a corrected two-dimensional intensity distribution by removing blooming signals and analyzing the corrected two-dimensional intensity distribution for the supplementary detection of surroundings objects in addition to the primary distance determination method.
