Learning Information
1 – Aims
The objectives of this photogrammetry tutorial are as follows:
- Learning about software that, by means of photographs, can create 3D models.
- Knowing what photogrammetry is and its scope of application.
- Keeping in mind the recommendations before making a photogrammetric project.
- Creating a three-dimensional model from photographs taken with Recap Photo or Regard3D software.
2 – Learning methodology
The teacher will give an explanation about photogrammetry of 15 min.
Students will read this tutorial and watch the video.
Students will follow the steps shown in the video.
They will have to upload the photographs at least 24 hours in advance, so that the model will be available during the explanation.
Building the model in ReCap Photo.
Creating the point cloud in CloudCompare.
Use ReCap to save with .rcp format.
Open the model in Revit (this step is not mandatory).
3 – Tutorial duration
The practice described in this tutorial will be carried out in a computer classroom.
It will last 3 teaching hours.
4 – Necessary teaching recourses
Computer room with PCs with Internet access.
Software required: ReCap Photo, CloudCompare, Regard 3D (optional), Revit (optional).
Hardware required: PCs, camera.

6 – Deliverables
To assess the achievement of the practice, students will write a report of 3 pages maximum.
In this report, the student will explain the steps taken in practice, the difficulties found and the decisions taken. The report will be illustrated with photographs during the process of each software.
7 – What we have learned?
