Abstract:

Photogrammetry is one of the modern methods of mapping and can also be used as a tool for digitizing small and large objects, with good results, which currently occupies its place in practice. The use of photogrammetry is no longer limited to geodetic activities, but its wide range of uses also includes the protection of cultural heritage, modeling of the environment in the world of robotics, navigation and many others. Based on the above, it can be seen that it is important to implement photogrammetry procedures in the teaching of computer science. In addition, it allows the connection of knowledge from several subjects, such as mathematics, geometry, physics or optics, and thus supports between subject relationships, which is another important element, which we also follow in this paper. The result of the work is a realistic three-dimensional model of the mapped object. Acquisition of this model is conditioned by obtaining photographic images from which the model will be created. Of course, we can use expensive equipment and apparatus, but that is by no means our goal. To obtain photo shots, we will use only such equipment that students already have at their disposal today - mobile phones, tablets, digital cameras, etc. Creating a model does not necessarily end the work, on the contrary, with the help of a suitable software tool allows e.g. determination of its dimensions, placement in the coordinate system or for the already mentioned protection of cultural heritage. In our paper, we will focus on the description and exclusion of such key issues that will significantly affect the quality of the model, which can lead to disappointment in students, reduce their enthusiasm for this work or even loss of interest. We will point out the importance of the preparation and selection of photo shots and the correct process of creation by both the teacher and the students, which we will also substantiate with the results of the work. We will also point out the creation of a model in the pix4D software and implement the whole procedure into computer science lessons, focusing mainly on secondary schools, taking into account the specified range of lessons. Of course, we aim to teach students to create such models without the help of a teacher.
