Monitoring object shape and deviation from design

A method comprising:

• generating a registered first three-dimensional (3D) point cloud based on a first 3D point cloud and a second 3D point cloud, the second 3D point cloud based on first sensor data from a first sensor, and the first 3D point cloud based on a 3D model representing an object at a stage during or after a manufacturing operation, the first sensor data corresponding to the object undergoing the manufacturing operation;
• generating a registered second 3D point cloud based on the first 3D point cloud and a third 3D point cloud, the third 3D point cloud based on second sensor data from a second sensor, the second sensor data corresponding to the object undergoing the manufacturing operation;
• generating a combined 3D point cloud based on the registered first 3D point cloud and the registered second 3D point cloud;
• performing a comparison of the combined 3D point cloud with a mesh model that is based on the 3D model;
• generating, based on the comparison, output data indicating differences between the object as represented by the combined 3D point cloud and the object as represented by the 3D model, wherein the output data indicates that a distance between a first feature of the object and a second feature of the object is different than a corresponding distance of the 3D model;
• and
• providing the output data to an output device, the output data provided during the manufacturing operation.

A non-transitory processor-readable medium storing processor-executable instructions that, when executed by a processor, cause the processor to:

• generate a registered first three-dimensional (3D) point cloud based on a first 3D point cloud and a second 3D point cloud, the second 3D point cloud based on first sensor data from a first sensor, and the first 3D point cloud based on a 3D model representing an object at a stage during or after a manufacturing operation, the first sensor data corresponding to the object undergoing the manufacturing operation;
• generate a registered second 3D point cloud based on the first 3D point cloud and a third 3D point cloud, the third 3D point cloud based on second sensor data from a second sensor, the second sensor data corresponding to the object undergoing a manufacturing operation;
• generate a combined 3D point cloud based on the registered first 3D point cloud and the registered second 3D point cloud;
• perform a comparison of the combined 3D point cloud with a mesh model that is based on the 3D model of the object;
• generate, based on the comparison, output data indicating differences between the object as represented by the combined 3D point cloud and the object as represented by the 3D model, wherein the output data indicates a distance between a first feature of the object and a second feature of the object is different than a corresponding distance of the 3D model;
