We have looked at the following software products: For this review, we’ve selected the most popular ones and those that can offer unique functionality. There are many products on the market and new ones are constantly appearing. These extra features can be crucial in choosing the program, that suits the specific needs of a user. For example, CAD-support operations, processing of LiDAR points together with the imagery, or generation of animated models and scenes. Additionally, many of the products that we will look at have additional, sometimes very specific, functions. The availability of the above features was considered a must for the solutions in this class. building 3D-models using the input imagery for texture generation.

creating DSM/DEM surfaces with a high degree of detail in TIN or GRID format.creating point clouds that meet the quality of aerial laser scanning.So, a typical solution for digital imagery processing has the following features: This review will consist of a series of short summaries where we compare every application to an abstract standard. The software products, that we are going to discuss here, are intended to solve similar problems that is why they are very alike. Products like Pix4Dmapper, ContextCapture, PhotoScan and many others have formed a distinguished class. Unmanned aerial vehicles are becoming more and more available together with drone acquired imagery/data, this contributes a lot to the development of automated photogrammetric processing.
