Avaluació i qualificació

Activitats d'avaluació:

Descripció de l'activitat Avaluació de l'activitat %
Seminars Attendance to all the seminars, punctuality in all the activities related to the module and active participation in the seminars. 10
Lab assignment 1: Calibration of a simulated camera. This lab assignment is evaluated on the basis of the matlab code delivered by the students and a report explaining what has been done, what problems have aroused, and how the students have solved these problems. 15
Lab assignment 2: Project Based Learning activity on Invariant Features This lab assignment involves teamwork and oral presentation. The students will be evaluated on the basis of the oral presentation of their project (in teams of 3 students) and the code that they present. 30
Lab assignment 3: Epipolar Geometry This lab assignment is evaluated on the basis of the matlab code delivered by the students and a report explaining what has been done, what problems have aroused, and how the students have solved these problems. 15
Lab assignment 4: 3D Reconstruction This lab assignment is evaluated on the basis of the matlab code delivered by the students and a report explaining what has been done, what problems have aroused, and how the students have solved these problems. 10
Exam Coherence of answers with respect to the reviewed contents. Synthesis ability. 20

Qualificació

About evaluation:

50 % Exams (first exam 30%, final exam 70%). Summative evaluation (all contents apply to the second exam)
50 % Practical Sessions (Every exercise Mark >= 5/10)

To pass the module, the global mark must be >= 5/10

Criteris específics de la nota «No Presentat»:
Lab assignments are mandatory. Failure to deliver a lab assignment implies that the student will not be evaluated in the module.
