Abstract: A wear measurement system for a component is disclosed. The wear measurement system may have an imaging device configured to obtain a plurality of two-dimensional images of the component. The wear measurement system may also have a controller. The controller may be configured to generate a three-dimensional point cloud representing the component based on the two-dimensional images. The controller may also be configured to select at least two reference points appearing in each of a subset of images selected from the two-dimensional images. Further, the controller may be configured to determine locations of the two reference points in the three-dimensional point cloud. The controller may also be configured to determine an image distance between the locations. In addition, the controller may be configured to determine an amount of wear based on the image distance.

Abstract: A machine has a power source and a cooling system configured to circulate coolant between the power source and a heat exchanger. The cooling system has a first sensor configured to sense an ambient temperature and provide a first signal indicative of the ambient temperature and a second sensor configured to sense an actual temperature of the coolant and to provide a second signal indicative of the actual coolant temperature. The cooling system has a controller in communication with the first and second sensors to receive the first and second signals. The controller is configured to calculate, based on the ambient temperature and on a model for the heat exchanger, a predicted coolant temperature, and to compare the predicted coolant temperature to the actual coolant temperature. The controller is further configured to provide an alert based at least in part on the comparison.

Abstract: A wear measurement system for a component is disclosed. The wear measurement system may include an imaging device configured to obtain a plurality of two-dimensional images of the component. The wear measurement system may also include a controller. The controller may be configured to generate a three-dimensional point cloud representing the component based on the two-dimensional images. The controller may also be configured to overlay a computer model of the component on the three-dimensional point cloud. Further, the controller may be configured to project the computer model on the two-dimensional images. The controller may also be configured to select at least two reference points appearing in each of a subset of images selected from the two-dimensional images. The controller may be configured to determine locations of the two reference points in the three-dimensional point cloud, determine an image distance between the locations, and determine an amount of wear based on the image distance.
