Aggiungi una serie di immagini a un elemento

Preparazione da Desktop

One or more pictures can be added to the feature. Here is an example of how to proceed.

Tabelle

It is necessary to set up two tables. One table where the features are stored and one with a list of pictures.

Apiary

Campo	Tipo
id	Text (UUID)
geometry	Geometria
...

Apiary_pictures

Campo	Tipo
id	Text (UUID)
apiary_id	Text (UUID)
path	Text
...

Relazioni

Crea una relazione con:

• apiary Layer di riferimento
• id Campo di riferimento
• apiary_picture Layer che fa riferimento
• apiary_id Campo che fa riferimento
• strength Composizione

Widget

Apiary

Set the default value of the field id to uuid() or use the UUID Generator widget. There is no need to show it in the form.

Imposta il widget della relazione su relazione uno a molti e aggiungi la relazione al modulo

Immagine dell'apiario

Imposta il tipo di widget del percorso del campo a Attachment e aggiungilo al modulo

Drawing and sketching

QField has an in-app drawing and sketching functionality enabling you to directly sketch over and annotate images captured while in the field as well as drawing on top of a blank canvas or over a template.

Drawing templates

On top of annotating captured images, QField supports drawing from image templates. The following two methods are available to add templates:

• The first method is to create a drawing_templates folder located alongside a project file and populate it with images. Whenever that project is loaded, QField will register all images within that folder as drawing templates.
• Alternatively, you can add images into the drawing_templates folder found inside your QField app folder. If you are not familiar with that app folder, its location is shown at the bottom of the About QField overlay.

Templates shipped alongside projects as well as the QField app folder will be shown when users choose 'Draw a sketch' within attachments widget's 3-dot menu.

Geotagging

Lavoro sul campo

QField's internal camera will automatically geotag your pictures.

Information about location and direction of the pictures will therefore be baked into the image file.

Note

While with older Android versions it was possible to use other apps like the amazing OpenCamera app for taking pictures and preserving EXIF information from there, this is no longer with recent Android versions. Is recommended to disable Use native Camera in the settings to preserve EXIF information.

Recupero dei Geotag (EXIF) dal file immagine nella tabella degli attributi

Preparazione da Desktop

Sometimes you might be interested in automatically storing Geotags such as the latitude, longitude, orientation, etc. This information is also known as EXIF tags.

Per memorizzare le informazioni EXIF, attenersi alla seguente procedura:

1. Aggiungi un attributo per ogni tag EXIF nella tabella che contiene le immagini.
2. Nel modulo immagini, configurare il valore predefinito di ogni attributo per il corrispondente EXIF expression See QGIS EXIF function, e assicurati che Applica all'aggiornamento sia attivato.
3. I tag EXIF che QField può catturare sono elencati nella documentazione di QGIS (link sopra). However, this list might slightly vary depending on the mobile characteristics.
4. Capturing EXIF tags requires accessing the full physical path of the picture. Be sure to reflect this in the QGIS expression. Ad esempio, l'espressione exif(@project_folder + '/' + "path", 'Exif.Image.Orientation') recupera l'orientamento dell'immagine memorizzata in path. For more tags visit the QField EXIF reference documentation and the exiv library documentation.
5. Completed! QField now captures and stores the EXIF tags in the pictures table while taking pictures.

Dimensione massima dell'immagine

Preparazione da Desktop

Le impostazioni avanzate consentono di ridimensionare le foto alla massima larghezza/altezza in QFieldSync plugin > Configurazione progetto

Percorso dell'allegato configurabile

Preparazione da Desktop

QFieldSync provides the possibility to configure the path and the file names of picture attachments.

1. Go to *Layer Properties > QFieldSync plugin *
2. Scegli il layer, il campo e configura l'espressione

Use expressions to specify the path of the attachments. By default, pictures are saved into the "DCIM" folder, audio are saved into the "audio" folder and videos are saved into "video" with a timestamp as name.

Additional directories can be synchronized with pictures or other attachments. Extra paths can be configured in Attachment directories in the QFieldSync settings under project properties. All paths are relative to the project directory.
