Abstract
A method for determining a distance offset between a depth map of an indirect time-of-flight measurement device and a reference ground truth map includes emitting emission optical radiation by an emission circuit of the indirect time-of-flight measurement device. The emission optical radiation is sequentially modulating by N modulation frequencies. N is greater than or equal to three. The method further includes receiving, by a reception circuit of the indirect time-of-flight measurement device, reception optical radiation generated by the emission optical radiation reflected off objects of a scene and by optical crosstalk between the emission optical radiation and the reception optical radiation, and estimating the distance offset based on the reception optical radiation.
