SENSOR CALIBRATION FOR SPACE TRANSLATION

Calibration of various sensors may be difficult without specialized software to process intrinsic and extrinsic information about the sensors. Certain types of input files, such as image files, may also lack certain information, like depth information, to effectively translate regions of interest between images taken from a different perspective. Landmarks can be used to establish points for associating regions of interest between images taken from a different perspective and provided as an overlay to verify sensor calibration.

METHOD FOR CREATING MAP DATA
20230314170 · 2023-10-05 ·

A method for creating map data having lane-specific resolution. Mapping data are initially received, the mapping data being transmitted by a vehicle, and including a vehicle trajectory and at least one object feature. Once the mapping data has been received, it is checked whether map data for local surroundings of the received mapping data are present. In the event the check indicates that no map data are present, map data are created from the mapping data and stored in a memory. In the event the check indicates that map data are already present, the map data are compared with the mapping data. If this comparison reveals that the mapping data differ from the map data, the map data are adapted, the adaptation taking place on the basis of a weighting factor. The adapted map data are subsequently stored in the memory.
