DETERMINING A LENS COVERAGE CONDITION OF A LIGHT-BASED SCANNING DEVICE ARRANGED IN A VEHICLE

A computer system (100; 500) comprising processing circuitry (102; 502) configured to obtain light data (110) from a light-based scanning device (20); obtain trajectory data (112) of an upcoming trajectory of a vehicle (10); generate a frame of reference (30) for the light-based scanning device (20), the frame of reference (30) indicating positional relationships of a plurality of light points (32) based on the light data (110) and a plurality of trajectory points (34) based on the trajectory data (112); for one or more given trajectory points (32), identify a non-overlapping region (36) in the frame of reference (30) where no light points (34) are collocated at said one or more given trajectory points (32); and determine the lens coverage condition based on a position of the vehicle (10) in relation to the identified non-overlapping region (36).
