Systems and Methods for Estimating Object Weight Using Camera Images
28 Dec 23
In some aspects, the techniques described herein relate to a method for object weight estimation, including: training an object identification model; receiving one or more images from a camera positioned on a machine engaged in a lifting operation; feeding each of the one or more images into the object identification model; receiving, from the trained object identification model, a predicted object corresponding to the object to be lifted by the machine and a probability that the predicted object corresponds to the object being lifted by the machine; and estimating a weight of the object based on at least the predicted object and comparing the estimated weight to lifting parameters associated with the machine when the probability is greater than a selected confidence threshold.
