Tiivistelmä
In the era of blooming information technology development, photogrammetry as a science is gaining massive public interests for its proven cost-efficiency and usefulness. At the moment, there are various software and hardware commercially available for consumers to select based on their own preferences. However, the abundant availability also comes with a difficulty in selecting of suitable options without allocating significant effort and resources on trials and errors. Fortunately, studies and reviews have been conducted to provide partial references to help the selection. With the same purpose, this study gave insights into two (02) different photogrammetric software and acted as reference material for future researches by carrying out a comparative case modeling between ReCap Photo-to-3D web service and Agisoft PhotoScan Professional.
Materials for this study were aerial photographs acquired from a separately organized UAV project of an area in Hiedanranta, Tampere. In addition, ground control points were created to help in geolocating the plot of land during modeling. The same data set was used in the photogrammetric applications to build two (02) 3D models. Results were collected for comparison with the assistance of a 3D data analyzing engine named CloudCompare. The workflows were thoroughly documented and user experiences were also discussed.
With a step-by-step guide from scratch to finish, ReCap web offered an almost effortless modeling process with minimum control over the project. On the other hand, PhotoScan, with a variety of commands and functions, provided users additional control over a project while closely assist through comprehensive tutorials. Despite dissimilar workflows and modeling tool sets, results including point clouds, mesh models, DEMs, and orthophoto were in good quality and comparable between two (02) photogrammetric programs. It could be seen that ReCap web is a good tool to get to know photogrammetry and 3D modeling, and PhotoScan by Agisoft is undoubtedly an excellent alternative engineering tool to actively manage workflows and results throughout the projects. However, the choice of software relies heavily on different factors including requirements of the projects as well as of the users.
