To begin, you have to download some packages listed in the requirements.txt file To use main.py, you also have to download Module folder. If you want to open anamorphosed speckle project, you can download the Open_project.py file
Main structure for deck.yaml file:
Camera:
Focal_length: 50 #mm
Sensor_height: 29 #mm
Input_speckle:
Step: 500
Begining: 3
Height: 27e-2
Width: 21e-2
Path: './Banque_Speckle/2mm'
Generic_name: 'Speckle_'
NbImage: 1
Position_centre: [[2, 0, 0], [2, -21e-2, 0], [2, 21e-2, 0]]
Surface :
a: 0
b: 0
c: 1
Radius : 0.4
Position : [3, 0, 0]
Surface_type : 'Cylindre'
Wingframe : [[ 2.6, 0., .5],
[ 2.6, 0., -.5],
[ 3., -0.4, 0. ],
[ 3., 0.4, 0. ]]
Output_speckle:
Height_printable: 27.9e-2
Width_printable: 21.6e-2
Print_path: './ImagePrintable'
Camera:
Focal_length: 50 #mm
Sensor_height: 29 #mm
Enter your focal length and sensor height in mm in these variable. Field of view in degrees and radians will be calculated and printed out. It is also used to plot the field of view cone in the 3D viewer.
Input_speckle:
Step: 500
Begining: 3
Height: 27e-2
Width: 21e-2
Path: './Banque_Speckle/2mm'
Generic_name: 'Speckle_'
NbImage: 1
Position_centre: [[2, 0, 0], [2, -21e-2, 0], [2, 21e-2, 0]]
Due to the multitude of points in the speckle, to test the code, we only anamorphose a few points. The variable Step represents the anamorphic step. step=2 will anamorphose half of all the points of a sheet of speckles.
Begining variable represents the first index of the contour list calculated by OpenCV to be considered ine the anamorphosis. Usually begining=3 is often sufficient to avoid black filling of the result by the algorithm.
You need to implement the size of the speckle sheets you want to anamorphose and the size of the anamorphosed speckle sheets you want to get. Use the Height, Width. The unit is meter.
Path is the path of the classic speckle sheets folder.
Generic_name is the name of your speckle sheets. It as to be the shape of Generic_Name_XX with XX a number.
NbImage is the number of sheets you want to anamorphose.
In the Position_centre list you must put the center position of all your sheets. It is organised like [x, y, z] refering to the figure.
Surface :
a: 0
b: 0
c: 1
Radius : 0.4
Position : [3, 0, 0]
Surface_type : 'Cylindre'
Wingframe : [[ 2.6, 0., .5],
[ 2.6, 0., -.5],
[ 3., -0.4, 0. ],
[ 3., 0.4, 0. ]]
Then you must to implement the surface properties :
- (a, b, c) vector represents the normal vector in case of a plane surface and the axis of a cylinder in the case of a cylinder surface case.
Position=[Posx, Posy, Posz]array represents the position relative to the camera of a point belongs to the axis of the cylinder (if the surface is a cylinder).- Radius is the radius of the cylinder in the case of a cylinder.
- Surface_type is a string to tell the programm that you want to anamorphose on a
Cylindreor on aPlan. Only cylinder or plane surface case are implemented. - Wingframe is the border of your wing represented by 4 points. It will be useful to represent your wing in 3D and print the anamorphosed speckle. It is organised as [x, y, z].
Output_speckle:
Height_printable: 27.9e-2
Width_printable: 21.6e-2
Print_path: './ImagePrintable'
Height_printable and Width_printable variables are the height and the width of the anarmophosed speckle you want to print. Print_path is the path of the anamorphosed speckle sheets folder.
Image warping on a plane with cv2.warpPerspective. It was just a test program.

- Déplier une surface polynomiale quelconque.
- Effectuer l'anamorphose dans un espace où la caméra n'est plus le centre et orienté dans n'importe quelle direction.
