The dimensional accuracy is only limited by the quality and quantity of the input images. It means that the accuracy and resolution is limited just by the resolution of the detail in the images.
Total time of processing depends on quantity and quality of data inputs, as well as their mutual overlap. It approximately takes 5 Hour to model 1000 images
Depending on the requirements, and complexity of model.
Visual models for remote inspection can be delivered within a day, and models the require more data e.g. LIDAR, RADAR information including as-built drawings can take up to 2 weeks.
Generally anything can be modelled, but we would like to avoid reflective objects!
