Abstract
The invention relates to a method, system and computer program product for determining a position of a person with respect to a blind spot of a vehicle. In a first aspect, the invention relates to a method for determining a position of a person with respect to a blind spot of a vehicle. In a second and third aspect, the invention relates to a system and a computer program product, respectively, for determining a position of a person with respect to a blind spot of a vehicle. Embodiments of the present invention are discussed throughout the claims, description and figures.
Claims16
Method for determining a position of a person with respect to a blind spot of a vehicle, comprising the steps of:
- providing an ultra-wideband (UWB) item associated with the person;
- providing two or more UWB anchors on the vehicle;
- and
- determining a geofence along a perimeter of the blind spot of the vehicle;
- selecting a reference anchor from the two or more UWB anchors;
- determining a distance between the UWB item and the reference anchor based on a Two-Way Ranging (TWR) technique;
- determining a direction between the UWB item and two or more of the UWB anchors based on a Time Difference of Arrival (TDoA) technique;
- determining a position of the UWB item with respect to the two or more UWB anchors based on the determined distance and the determined direction;
- and
- determining whether the UWB item is in the blind spot of the vehicle by comparing the determined position of the UWB item to the determined geofence.
System for determining a person's position with respect to a blind spot of a vehicle, comprising a UWB item for the person and one or more UWB anchors for positioning on the vehicle, wherein the system is configured for determining a geofence along a perimeter of the blind spot of the vehicle, wherein the system is configured for:
- selecting a reference anchor from the two or more UWB anchors;
- determining a distance between the UWB item and the reference anchor based on a Two-Way Ranging (TWR) technique;
- determining a direction between the UWB item and two or more of the UWB anchors based on a Time Difference of Arrival (TDoA) technique;
- determining a position of the UWB item with respect to the two or more UWB anchors based on the determined distance and the determined direction;
- and
- determining whether the UWB item is in the blind spot of the vehicle by comparing the determined position of the UWB item to the determined geofence.
A non-transitory computer-readable medium storing computer-executable instructions for determining a person's position with respect to a blind spot of a vehicle and determining a geofence along a perimeter of the blind spot of the vehicle, which, when executed by a processor, cause the processor to:
- select a reference anchor from two or more UWB anchors, preferably wherein two or more UWB anchors are provided on the vehicle;
- determine a distance between a UWB item and the reference anchor based on a Two-Way-Ranging (TWR) technique, preferably wherein the UWB item is associated with the person;
- determine a direction between the UWB item and two or more of the UWB anchors based on a Time Difference of Arrival (TDoA) technique;
- determining a position of the UWB item with respect to the two or more UWB anchors based on the determined distance and the determined direction;
- and
- determine whether the UWB item is in the blind spot of the vehicle by comparing the determined position of the UWB item to the determined geofence.
