Garmin produces action cameras under the name Virb. Mapillary for iOS has an integration with the Virb so you can use the camera via the Mapillary app both when capturing and uploading (integration with Android is upcoming). But since both the Virb X and Virb XE have a GPS receiver built in, the cameras are quite easy to use outside the Mapillary integration as well. The Virb XE is a newer and more expensive model, but also faster and more trustworthy in long, intense capturing sessions.
Via the integration built into Mapillary for iOS, you can start and stop capture from your mobile device. It also makes sure that capture is automatically paused when you stop moving for some reason. Images are transferred to the phone and you can review, delete, and upload them as regular sequences in the app.
- Start with formatting the camera’s memory card (we suggest you do this before each Mapillary session).
- Make sure "WiFi" is enabled on the camera and mode is set to "Mobile".
- Change to the Garmin WiFi on your phone.
- Go to the camera screen in the Mapillary app and tap on the WiFi button to search for and connect to the external camera. If the phone can’t find the camera, make sure you are on Garmin WiFi and try restarting the Mapillary app. You can also try switching the Garmin’s WiFi off and back on.
- You will get a preview on the app screen, so you can verify you have a good view (straight against the horizon and no parts of your vehicle visible).
- Capture as usual. The app will control the Garmin to capture every 0.5-2 seconds (you can change this in Settings).
- Transfer images directly after the capture or do it from the Uploads view later (you must have the camera connected for that).
- Review and upload as usual. Note that the images are saved on the memory card in the Garmin camera until you delete them yourself.
Note that with a Virb, the app uses the camera's GPS and not the phone's GPS. If the images have the wrong GPS position or are missing it completely, make sure to check that the camera has a GPS fix before you start capturing.
- Attach the camera (you can use e.g. the GoPro bike mount kit, or try 3D printing these).
- Do a couple of test shots to see that the images are straight and the horizon is where you want it (preferably in the middle), and no parts of your car/bike are in the image.
- Set the camera to time-lapse mode with 2 s interval (or different, according to your moving speed).
- After verifying that you have a GPS fix, start moving and start the camera. Check the camera screen from time to time to make sure you still have a GPS fix and enough battery.
- Stop and start when it makes sense to do so, at natural sequence gaps or when there is something you don't want to capture.
- When you are done riding, copy the images over to your computer. Look through them quickly and delete the bad ones.
- Before uploading the images using the web uploader, it is useful to organize them in sequences since the uploader needs all images in a sequence at the same time. You can do it manually or use a script. (With images captured in time-lapse mode, the script automatically finds the cutoff points and copies the images into subfolders for you.)
- Use the web uploader to upload your images. Do one folder at a time to have the correct sequences.
- If you are not able to upload sequences one by one, your images will eventually still be sorted into sequences. We have a bot running for this, but you should consider that it may take a few days until your bulk uploads get split into separate sequences.
