A method includes generating a first simulated environment. The first simulated environment includes a route for a simulated vehicle. The method includes determining a set of locations within the first simulated environment for a set of objects. The method includes determining a path for the simulated vehicle based on the route and set of locations. The method includes generating a set of simulated environments based on the first simulated environment and set of locations. The method includes generating a set of images based on the set of simulated environments, the path, and the set of non-deterministically generated objects. The non-deterministically generated objects include unrealistic objects and optionally include realistic objects. The method includes training vehicle guidance models using the set of images which may include abstract or unrealistic objects. The trained vehicle guidance models may be directly used on real vehicles in corresponding real world environments.

The degree of concrete surface roughness contributes to the bond strength between two concrete surfaces for either new construction or repair and retrofitting of concrete structures. Provided are novel systems and methods with industrial application to quantify concrete surface roughness from images which may be obtained from basic cameras or smartphones. A digital image processing system and method with a new index for concrete surface roughness based on the aggregate area-to-total surface area is provided. A machine learning method applying a combination of advanced techniques, including data augmentation and transfer learning, is utilized to categorize images based on the classification given during the learning process. Both methods compared favorably to a well-established method of 3D laser scanning.
