Learning unit contents
THIS COURSE WILL NOT BE ORGANIZED IN 2021-2022.
The "3D Acquisition" course will enable you to master the key principles related to the acquisition of spatial data. Your objective is to complete the course by carrying out the various missions requested, linked to a final project.
To help you realize this project, I provide you with 3 tools:
- Theoretical courses, to prepare you and allow you to rely on a clear basis
- Practical work, to directly apply theoretical learning
- Supervised support based on the deliverables of the various missions.
Content of the teaching unit
Reality Capture
The principles
Instruments and methods
Sensors and acquisition vectors
3D applications
Laser scanning
Principle of Laser scanning
The different Laser Scanners and mobile platforms
Laser Scanning: errors
Laser Scanning: In practice (Acquisition)
Laser Scanning: Assembly (Registration)
Laser Scanning: Processing of "point cloud" data
Dense photogrammetry "Structure from Motion (SfM)"
Introduction to 3D photo-reconstruction
The "classic" photogrammetry
Measurement platforms
Principle of SfM Photogrammetry
3D photo-reconstruction: in practice
Camera settings for shooting
Land acquisition
Multi-view reconstruction
The "SfM" processes
Dense matching
Image interpretation
3D reconstruction, orthoimage and DSM
Data fusion and 3D assembly
Make floorplans from 3D data
Extract data information from point clouds
Introduction to 3D mesh processing
Control and characterization of errors and precision of techniques
Assembly, Georeferencing and 3D implementation
Production of maps, plans and geo-referenced 3D reconstructions
These different points are addressed in a theoretical way, then put into practice directly according to a project established during the first theoretical session.
Learning outcomes of the learning unit
Become an expert in "Reality Capture", able to manage 3D survey projects from A to Z.
Prerequisite knowledge and skills
- Geodetic systems
- Geometry and trigonometry
- Least squares
- Epipolar Geometry
- Use of word processing softwares
- Use of spreadsheets and/or programming scripts
- Make a professional presentation
- Topography & Use of total stations + GNSS receivers
- Réalisation de présentation par diaporama
Planned learning activities and teaching methods
The training process is relatively simple but not necessarily intuitive if you are used to traditional training.
You will not take courses that lead to exams with quotations.
You will carry out missions that lead to reports, calculations and/or support to validate the acquisition of skills.
In other words, to do this training I ask you to acquire all the essential skills of a professional.
The projects are reconstructions of professional scenarios, simulations of the daily life of a professional, if you prefer. In the project, I give you a list of deliverables or tasks to be carried out in compliance with requirements. Then it's up to you. As in real life, these activities can take several weeks (or even months).
The idea of project-based pedagogy is to enable you to learn under conditions that are as realistic as possible. So the projects push you to:
Contextualize your practices
Plan your work in the short/medium/long term
Find the information you need to solve a problem
Create quality deliverables that you can use during interviews
Present your work publicly
Improve yourself with resources and feedback
The logistical and scheduling organization can be variable, but a certain amount of theory will be provided before each mission is carried out. The missions will partly and/or fully be realized in pratical sessions
Mode of delivery (face to face, distance learning, hybrid learning)
It is a face-to-face teaching. The theoretical and practical sessions in controlled autonomy take place on the day scheduled in the course schedule.
Recommended or required readings
Provided in class
Any session :
- In-person
oral exam
- Remote
oral exam AND written work
- If evaluation in "hybrid"
preferred remote
Additional information:
A permanent non-certifying self-assessment is ensured during the practical exercise sessions by strong interaction between students and teachers.
The certification evaluation is carried out on the basis of the different deliverables and supports.
6 families of criteria are studied:
Field/practicals activities
Reports and deliverables
Mission-specific techniques
The different calculations and logical reasoning
The graphical report
The quality of the defense
The questions asked during the student's support are inspired by the imperfections of the different deliverables.
The evaluation criteria are: clarity, coherence, logic, rigour, precision, exhaustiveness, conciseness, relevance, transversality (within and between courses), quality of mathematical interpretations (e. g. mathematical significance of different coefficients in equations), physical (e. g. dimensions and units, order of magnitude - scaling) and geographical (single and multivariate spatial-temporal interaction and nature - type - and significance of variables - e. g.).
The critical sense of the data used (qualification, nature, meaning, representativeness, standardization, etc.) and the methodological choices (justification of the choice of methods, appropriate thresholds, etc.) will also be taken into consideration during the evaluation.
In addition, the answers will also be evaluated on the basis of the quality and originality of the graphic illustrations, and the spirit of synthesis and relevance of the different deliverables.
The final defense is the outcome of the project, and two scenarios are emerging:
Either the student demonstrates full control of the teaching unit and validates the course
Either the student presents areas for improvement on certain points which will be the subject of a second defense at the end of the quadrimester in order to rework and perfect any deficiencies
