This article provides three tips on processing images with GoPro cameras:
1) Use images with the highest resolution.
2) Properly set up the number of images taken per second.
3) Ensure 80% for terrestrial imagery and 60% for nadir UAV flights.
In order to use GoPro HERO2, GoPro HERO3, GoPro HERO3+, GoPro HERO4, GoPro HERO Session, and other related GoPro cameras for processing with PIX4Dmapper:
1. Capture images with the highest possible image resolution. Check the camera's manual or contact GoPro to verify the highest possible image resolution for the camera.
2. If you cannot trigger the camera based on distance, set up the image rate to take an image every n seconds using GoPro's photo time-lapse:
n depends on the speed of the camera movement:
- For walking: n = 0.5 − 1 seconds
- For flying with Phantom Vision: n = 1 − 2 seconds
3. Ensure sufficient overlap (at least 80% for terrestrial imagery, and 60% for nadir UAV flights: for more information about recommended flight plans: Step 1. Before Starting a Project > 1. Designing the Image Acquisition Plan - PIX4Dmapper).
Last but not least, create a project and process the images following the step-by-step instructions: Getting Started Index - PIX4Dmapper.
PIX4Dmapper can also process video frames obtained with the GoPro Hero4 Black.
In order to process frames from the GoPro Hero4 Black:
1. Acquire the video using the 4K resolution.
2. Create a new project importing the video captured. For step-by-step instructions: How to use Videos for Processing - PIX4Dmapper
3. Ensure that the right camera model is selected: HERO4Black_0.0_3840x2160_4k_video. For more information on how to edit the camera model: How to use the Editing Camera Model Options - PIX4Dmapper
Bonjour,
J'ai essayé
12 MP
champ de vision large
Pas de stabilisation d'image
images toutes les 0,5 seconde
déplacement : marche à pied
j'ai l'erreur
Hello,
we have already answered to you via ticket system, but I'll share the answer on the Community so that it might be helpful also for other users encountering the same issue.
The software has not recognized your camera model because the images were taken with the GoPro HERO 6, which is not in our camera database at the moment. Being this the case, Pix4D Desktop automatically applied some default parameters and the key thing is that it automatically applied a perspective camera model to the images but they are clearly captured with a fisheye lens. In this case, you need to edit the camera model parameters specifying the camera is using Fisheye Lens and entering the necessary parameters, as explained in this article on How to calibrate a Fisheye Lens Camera.
Cheers,
Alice
Do you plan to add GoPro Fusion 360 to the camera models?
Cheers,
Henri
Hello Henri,
If the camera can provide the equirectangular format, it should work with Pix4D.
If you open a ticket, you could maybe share some images with us and we could test it.
Regards.
Was wondering if there has been work with the later Gopros they are up to 8 now. I realise from my point of view I am still at a student level but I currently hang a gopro off my planes from time to time and capture the landscapes. My gopro session 5 doesn't have the GPS but still makes passable maps that I can use for my homework.
The later gopro has the GPS so that seems like a big upgrade having that tagged in the photos. Just wondering if it would be supported and then worth the upgrade. Since it can be multi purpose it would be an easy sell until I can justify a industrial plane and camera set up.
Thanks
Hi Shawn,
You should be able to process the images obtained from the new Gopros or any camera. The most crucial factor is to have a good overlap during image acquisition. And if you still have an issue during calibration, you can always calibrate your camera, and you should not have any problem while processing. To do so, follow the steps explained in our support article, How to calibrate a Perspective Lens Camera.
Regards.
