How to process RGB and multispectral drone imagery in Pix4D (Drones in agriculture series, 2/7)

0:00 Background and installation
1:36 RGB (true-color) image processing
8:00 RGB outputs
17:49 Multispectral imagery processing
22:04 Multispectral outputs

This tutorial covers how to create 3D models and a variety of 2D outputs based on typical drone-based imagery. This focuses on processing of RGB and multispectral drone imagery with Pix4dMapper. Thermal data can also be processed using the exact same methods as RGB imagery, except by choosing "Thermal camera" as the processing template rather than "3D map". The process of reconstructing models from images (photogrammetry) is the starting point of drone data processing in agriculture and plant sciences.

If you found these methods useful, please consider citing our recent paper in the journal Remote Sensing:

What a complete, fun and great explanation. Thank you.

Very great tutorial. This is very helpful!

[lukescott]

This was great. Gonna go check out the data analysis vids

Sir are you uses GCP and ICP for the photo when aquisition ?

[eusunhan]

A great step-wise demo! Thank you. I was wondering if we should take the photo of the calibration panel before or after the flight - or both times?

What kind of processor/video card does youre pc have? What kind of pc/laptop should I buy?

[ramandeepkumar]

its really very nice vedio....can you please add any single vedio showing stepwise process to process or get 5 vegetation indices from red edge mica sense

Hii travis its a great video, i have facing a problem process multispectral images from dji p4 multispectral especially on radiometry and calibration we dont have the reflectant panel. What is the step if we dont have the reflectant image for calibrate.

I am interested in how to use image processing information in regresión models. Do you have any githun project, paper or other kind of literature I can check?

Hi did you fly a nadir grid mission or did you choose an oblique camera angle for that example here?

[abderrezeqmahia]

Thanks for the useful video and informations.

I would ask you please about processing images, is it the same way to process images got from an RTK drone, images got from a simple drone (without RTK), and images got from PPK method ?
I wanna know the difference between processing images in the three cases.
Thanks.

Hi Travis, Your videos are great and very helpful! A question: what exactly is the "reflectance" layer that Pix4D exports? Do you know if I can instead take an RGB geotiff and break out the red, green, and blue bands as separate tifs and calculate indices such as VARI on those? Thanks!

[gerardopreckel]

great video! question: do you know where can I find some free drone RGB or multiespectral set of images to test the program? thank you!

[hichemhamami]

Thanks for your videos
Please how can I get RGB TRUE COLOR in web Open Drone Map ?
Thank you

I have images from a Mica Sense RedEdge-M camera from my UAV and i want to calibrate the reflectance in the AgiSoft Meteshape but, i dont have photos from the calibration panel. How can i calibrate the reflectance without it? There is some way were i can create a calibration image on QGIS using DN values? Or maybe extract the reflectance on QGIS and somehow import this on Agisoft? Hope you can help!

We are using Parrot Blue Grass, Can we Capture Imagery Manually of Small Agriculture Plot ? At what Minimum Altitude / Height Parrot Blue Grass Sequoia Capture images

[ranadeepmahendra]

hey can you provide a dataset drive link so I can try them in pix4d

[lifewithducks]

I want to connect on zoom meeting for this ..

[arniewaddell]

Travis, great work. Do you not require GCPs to accurately geolocate the images?

[ponkiyaharshil]

You not provided DATA, how i can get Drone DATA???
