Menu: Analyze / Détection de caténaires
L'outil de détection de lignes électriques a été développé pour détecter et vectorizer les lignes électriques de façon automatique. Suite à la première ouverture de l'outil, une liste vide des lignes électriques est affichée ainsi que plusieurs options dans la partie droite de la fenêtre. Il y a une barre d'outils permettant la gestion des lignes électriques ainsi que des options d'enregistrement au bas de la fenêtre.
Fenêtre principale
Invites the user to click on an existing power line to be identified on screen; the power line in question will be highlighted in the list
There are also a few options at the bottom of the window:
- Save: Saves the selected power lines to a PWL or TXT format.
- Load: Loads a PWL or TXT file to the item list while clearing existing items.
- Add: Adds a PWL or TXT file to the item list. Does not clear existing items.
- Export: Exports selected power lines to DXF or shapefile format.
Add manually
In this section it is possible to add a power line manually. This option can be used for hard-to-detect power lines or for lines that require a specific vectorization.
- Add a line: This button will add an empty line to the list of power lines on the left of the window.
- Start/Stop pick: After clicking on Add a line, the Start pick mode is automatically active. This will set the tool to picking mode – where the user may vectorize a power line manually by clicking on points in the main screen. Once picking the line is complete, click on Stop pick to exit picking mode.
It’s also possible to add points to an existing line. Simply select the line in the list and click on Start pick. Pick as many points as necessary and click on Stop pick to exit picking mode.
Classify
The classification tool is used to classify power lines detected using ''Detect from points'' to a specific class.
