As you, we are passionate about drones and agricultural applications. At the moment, we have developed a low-cost camera that would let you know about health of plants and crops through NDVI multispectral analysis. The good news is that we will launch it by a crowdfunding project in Kickstarter. Here there are the main features of uSense camera.
To drive our product to the right market we would like to know your comments and thoughts regarding the next questions:
1. Type of uses that you will do it with a camera like that.
2. What are the features that you will love add it?
3. How much you will be willing to pay?
Thank you for your comments, we appreciate the time and any link that you think could help us as well.
If you want to know more, don't hesitate to contact us!
It is somewhat complicated to have to sync 4 cameras and then postprocess to get a single image. It seems that there is not one camera with NIR+green+blue or NIR+green+red which is what you get with modified consumer cameras and is generally very usefull. It does not specify what exactly is meant by NIR. It would be important to know how curved the lens is, what distortions there are at the edges and how much of each picture is really useable.
If you need some collaboration Please let me know. Our terrain in Italy has many differences within the same areas and multispectral cameras could be a great help. We are going to focus on PF, so just send a message if you are open to collaborations.
The market here is huge.
This seems to me very interesting, especially for countries in the Third World.
but I think it is difficult to handle accommodate multiple cameras (4x55g) in a drone.
Some data would be important to now:
Reload Time of Camera. Focal length. FOV, Wavelength diagrams of the bands.
It would be nice to integrate a RedEdge. What software is usable for post-processing?
We are interested in the project and we would like tu help to move forward.
We fly missions in Mexico in the field of environmental protection and agriculture, often under very difficult conditions (but also very real for southern countries).
Thanks for the feedback. Indeed, it is complicated to sync 4 cameras but it's possible with external trigger. Pictures from the cameras could have a small delay (10-50ms) between them but It stills generate a good enough photos for post processing.
At the moment we don't have a NIR+Green+Red single camera but we can make one. Could you let me known which applications need NIR+G+R bands?.
In the next post I will upload the spectral curve.
Thanks for your offering. I will definitely contact you.
Actually, the first purpose of our project is to serve emerging economies and enthusiast worldwide that could not afford a expensive multispectral camera. It will allow the use and application of precision farming and citizen science.
Regarding the camera array, we have accommodated 4 camera in a 3DR X8+, total weigh is around 235g that easily could be handed by that drone.
Currently we are using Pix4D to post-processing but also we're exploring more options.
Finally, I want to say thanks for your interest and hopefully we can work together in camera testing.
I forget about the specs:
Reload time of camera: <2s.
Lens: f/2.8 Aperture, 82° HFOV, 23mm, Non-fish eye for low distortion.
We are also testing other lens configuration, what do you think about this lens set?
PD. I will post the spectral response asap.
During the last 7 years I had several customers that use drones for NDVI images .
Their path is to learn to use the drone first, so they mount a cheap modified camera , then, when, and if, they have success in this first part , they buy a high end multispectral camera .
If the new Parrot Sequoia will maintain promises , that will be the reference product for NDVI images and of course 3000 USD, that seems a lot of money, but usually customers learn quite fast that also the time to get valuable results with NDVI images has a cost.
Do you have a working prototype ?
If not Kickstarter will not let you start a campaign .
So why don't you show us some NDVI pictures of your prototype ?
At a first glance your product appears to me a little bit tricky concerning cameras triggering and sync.
Glad to meet a colleague with that so much experience in industry. If you're interested I would like to share some thoughts since my experience comes from research in plants spectroscopy and hardware design.
We already have a working prototype so in the next week I will post some images. At the moment we're focus in getting the first reaction from the drone community.
If Kickstarter does not approve our campaign we will go through Indiegogo because we need pre-sales to start production.
Could you tell me, which features of Sequoia are the most important to you and your clients?.
Up to 1 FPS
RGB Camera 16 Mpx
IMU + Magnetometer
Configuration over Wi-Fi
thanks for the feedback. We will try to include that features in our camera. I think 16MP will be included in uSense. Is sunshine sensor used to auto calibrate white balance?.
A fully-integrated sunshine sensor captures
and logs the current lighting conditions and
automatically calibrates outputs of the camera
so measurements are absolute.
I forgot to mention that the Sequoia has also a GPS built in the sunshine sensor.
