Abstract. The aim of this article is to demonstrate the possibility of using photogrammetry as a method for documenting and digitizing data reconstructed from a display hologram. We discuss the importance of the task of digitizing information from holograms and the search for its solution, which will allow display holography to gain new distribution. Textured point clouds were obtained for the object and for its image reconstructed from the display reflective type hologram using monochromatic radiation. The requirements for the experimental setup for the digitization of the reconstructed from hologram object wavefront, as well as for the number of photographs for the hologram capturing are formulated and explained. The calculated three-dimensional models of the object and the reconstructed object wavefront were compared according to the Pearson correlation criterion. The achieved correlation value is 0.903. The results of comparison of two 3D models in the estimation of the standard deviation are given.
