  "textContent": "The present disclosure relates to a method performed by a field monitor system (1) of a vehicle (2) for performance monitoring and evaluation of an ADAS or autonomous driving feature (3) of the vehicle. The field monitor system stores (1101), during a time period (T) ranging from a first time point (t1) to a second time point (t2), a range of perception data (4) on which the ADAS or autonomous driving feature is pertinent derived from a perception system (21) adapted to estimate surroundings of the vehicle. The field monitor system further determines (1002) based on post-processing a portion (40) of the range of perception data ranging back from the second time point to an intermediate time point (tintermediate) between the first and second time points, ground truth intermediate data (6i, 6i', 6i\", 6i\"', 6i\"\") at the intermediate time point, which ground truth intermediate data reflects estimates of vehicle surroundings at the intermediate time point conditional on the portion of the range of perception data. Moreover, the field monitor system determines (1003) based on analysis of the ground truth intermediate data in view of intermediate perception data (4i, 4i', 4i\", 4i\"', 4i\"\") out of the range of perception data corresponding to the intermediate time point, an accuracy deviation measure indicating deviation between the ground truth intermediate data and the intermediate perception data. The field monitor system further communicates (1004) acknowledgement data (8) when the accuracy deviation measure exceeds a performance threshold.The disclosure also relates to a field monitor system in accordance with the foregoing, a vehicle comprising such a field monitor system, and a respective corresponding computer program product and non-volatile computer readable storage medium.",
