1. A system comprising:
a non-transitory computer-readable medium storing a data structure representing a set of sensor components related to each other by a set of relationships, the data structure comprising:
a set of component representations representing the set of sensor components, wherein each component representation is associated with a plurality of intrinsic parameters for a respective sensor component;
an intrinsic model identifier for each intrinsic parameter of each plurality of intrinsic parameters for each component representation, wherein each intrinsic model identifier identifies an intrinsic parameter model from a set of candidate intrinsic parameter models for a respective intrinsic parameter of the sensor component represented by the respective component representation; and
a set of constraints relating component representations within the set of component representations to each other, wherein each constraint represents a relationship from the set of relationships; and
a processing system, comprising a processor, that calibrates the set of sensor components by:
extracting each intrinsic model identifier and the set of constraints from the data structure;
for each extracted intrinsic model identifier, retrieving an intrinsic parameter model identified by the respective intrinsic model identifier, from the set of candidate intrinsic parameter models for the intrinsic parameter;
constructing an optimization equation set based on the retrieved intrinsic parameter models and the set of constraints; and
calibrating the set of sensor components using the optimization equation set.
