1. A computer-implemented method, comprising:
receiving first image data from one or more sensors associated with a work machine and at a first time instance in a dig-dump cycle of the work machine, the first image data related to at least one ground engaging tool (GET) of the work machine;
determining whether the first time instance is closer to an end of the dig-dump cycle than to a start of the dig-dump cycle;
determining a first wear measurement of the at least one GET based on the first image data;
determining a first wear level of the at least one GET corresponding to the first time instance and based on the first wear measurement; and
determining whether the first wear level is indicative of a GET replacement condition, wherein:
based on determining that the first time instance is closer to the end of the dig-dump cycle than to the start of the dig-dump cycle and on determining that the first wear level is indicative of the GET replacement condition, generating an alert indicative of the first wear level, and
based on determining that the first time instance is not closer to the end of the dig-dump cycle than to the start of the dig-dump cycle:
receiving second image data from the one or more sensors and at a second time instance in the dig-dump cycle of the work machine, the second image data related to the at least one GET, wherein the second time instance is later than the first time instance;
determining a second wear measurement of the at least one GET based on the second image data;
determining a second wear level of the at least one GET corresponding to the second time instance and based on the second wear measurement;
determining whether the first wear level and the second wear level are indicative of the GET replacement condition; and
based on determining that the first wear level and the second wear level are indicative of the GET replacement condition, generating an alert indicative of the first wear level and the second wear level.
