Abstract
A surface evaluation system that includes one or more vision systems that generate target surface data during evaluation of a surface, the one or more vision systems comprising two or more of: at least one light, a camera, a structured light camera, a laser scanner and a 3D scanner.

A method, comprising:
- generating instructions to control an automated surface finishing system to apply a material to a target surface, the automated surface finishing system comprising a positioning system and a sanding end effector coupled to the positioning system;
- controlling one or more of a distance and an angle of a light relative to the target surface;
- receiving one or more images of the target surface captured by a camera while the light is illuminating the target surface at an incident angle relative to the target surface;
- processing the one or more images to identify a feature in the one or more images that indicates a defect in the target surface, the feature comprising a shadow in the one or more images, the defect comprising a low spot in the target surface;
- and
- generating instructions, based on a location of the feature, to control the positioning system and the sanding end effector to avoid sanding down the low spot.

A method, comprising:
- generating instructions to control an automated surface finishing system to apply a material to a target surface, the automated surface finishing system comprises a positioning system and a sanding end effector coupled to the positioning system;
- controlling one or more of a distance and an angle of a light relative to the target surface;
- receiving one or more images of the target surface captured by a camera while the light is illuminating the target surface at an incident angle relative to the target surface;
- processing the one or more images to identify a feature in the one or more images that indicates a defect in the target surface, the feature comprises a shadow in the one or more images;
- after the target surface is sanded by the sanding end effector, processing one or more further images to determine whether the target surface meets a condition for surface quality;
- and
- generating instructions to control the positioning system and the sanding end effector to end sanding of the target surface in response to determining the target surface meets the condition.

A method, comprising:
- controlling a position of a scanner relative to a target surface;
- receiving, three-dimensional topography information of the target surface captured by the scanner;
- processing the three-dimensional topography information to determine a surface profile of the target surface;
- generating a toolpath and parameters for an automated surface finishing system based on the surface profile, the automated surface finishing system comprising a positioning system and a sanding end effector coupled to the positioning system;
- after the target surface is sanded by the sanding end effector, processing further three-dimensional topography information to determine whether the target surface meets a condition for surface quality;
- and
- generating instructions to control the positioning system and the sanding end effector to end sanding of the target surface in response to determining the target surface meets the condition.
