1. A computer-implemented method for triggering a sensor operation, the method comprising:
simulating a sensor operation of a first sensor, wherein the simulating the sensor operation of the first sensor comprises:
receiving a set of initial parameters associated with the operation of the first sensor;
generating a virtual sensor system based at least in part on the set of initial parameters; and
training a predictive model based at least in part on the set of initial parameters;
predicting, based at least in part on the predictive model, a time at which the first sensor will be aligned with a second sensor;
triggering the second sensor to perform the sensor operation comprising an image capture function relating to a common location for the first sensor and the second sensor based at least in part on the predicted time;
determining an error between the predicted time and an actual time that the first sensor was aligned with the second sensor;
providing feedback data comprising an indication of the error to the predictive model; and
re-training the predictive model based at least in part on the feedback data to improve a predictive capability of the predictive model.
