Claims15
A method for ascertaining a virtual camera position and camera alignment in order to allow the surroundings of a vehicle to be represented on a display of the vehicle on the basis of the virtual camera position and camera alignment, wherein the method comprises:
- utilizing a computing unit for performing the following steps:
- detecting the vehicle surroundings by multiple cameras of the vehicle and generating current vehicle surroundings information on the basis of the information of the cameras;
- providing memory on which multiple data sets are stored, wherein the data sets each comprises stored vehicle surroundings information which has been detected by multiple cameras of the vehicle, and comprises information on the virtual camera position and camera alignment assigned to the stored vehicle surroundings information;
- comparing the current vehicle surroundings information with the stored vehicle surroundings information of at least one data set of the multiple data sets;
- establishing at least one similarity parameter relating to at least one data set, wherein the at least one similarity parameter indicates, in each case, a degree of similarity of the current vehicle surroundings information to the stored vehicle surroundings information of the respective data set;
- if the at least one similarity parameter is greater than a specified threshold, reading the information on the virtual camera position and camera alignment of the data set which contains the stored vehicle surroundings information, and
- ascertaining the virtual camera position and the camera alignment on the basis of the read information on the virtual camera position and camera alignment.
A system comprising multiple cameras distributed around a vehicle, a computing unit comprising a processor for processing the information which is provided by the cameras, a storage and a display which is configured to represent surroundings information of the vehicle, wherein the computing unit is configured to perform:
- detecting the vehicle surroundings by multiple cameras of the vehicle and generating current vehicle surroundings information on the basis of the information of the cameras;
- storing multiple datasets in the storage, wherein the data sets each comprises stored vehicle surroundings information which has been detected by multiple cameras of the vehicle, and comprises information on the virtual camera position and camera alignment assigned to the stored vehicle surroundings information;
- comparing the current vehicle surroundings information with the stored vehicle surroundings information of at least one data set;
- establishing at least one similarity parameter relating to at least one data set, wherein the similarity parameter indicates, in each case, a degree of similarity of the current vehicle surroundings information to the stored vehicle surroundings information of the respective data set;
- and
- if the similarity parameter is greater than a specified threshold, reading the information on the virtual camera position and camera alignment of the data set which contains the stored vehicle surroundings information, and ascertaining the virtual camera position and the camera alignment on the basis of the read information on the virtual camera position and camera alignment.
