1. A system comprising:
a data processor;
an image receiver in data communication with the data processor; and
an image quality assessment system executable by the data processor, the image quality assessment system configured to:
receive one or more quality assessment images via the image receiver;
process the quality assessment images to determine if a quality of the surface texture features of an object or environment depicted in the quality assessment images satisfies a pre-determined quality threshold, the pre-determined quality threshold corresponding to a likelihood of a satisfactory result if images of the object or environment are used for photogrammetry;
generate an image quality map indicating image quality values corresponding to regions of the surface of the object or environment that have satisfactory or unsatisfactory texture features for photogrammetry;
generate instructions or prompts for a user, the instructions or prompts directing the user to perform actions with respect to the object or environment that will effect improvements of the texture features for satisfactory photogrammetry; and
initiate photogrammetry processing of the object images if the image quality map indicates the object images have an acceptable level and coverage of surface texture features for photogrammetry.
