For a year now, some iPhones and iPads include a lidar-based 3D sensor. Multiple apps have been published that use this functionality to offer 3D scanning of objects + rooms. It is however unclear what quality can be expected of the available solutions. in this bachelor thesis for 1 person, available hard- and software will be used to evaluate the various solutions and compare their strengths and weaknesses. For this, a setup has to be created that facilitates a 3D scanning process with repeatable results (handicraft experience is of advantage). Then, different 3D scanning apps should be used to scan the same materials, so that the results of scanning can be compared. Finally, the problems in the results should be analyzed to understand an undestanding of the achievable quality and the limitations. A comparison with a professional 3D scanner can be organized.
