Nebraska Plant Phenotyping: Spidercam
The University of Nebraska offers three unique plant phenotyping platforms. http://ard.unl.edu/phenotyping |
Located at the University of Nebraska's Agricultural Research and Development Center, a one acre field phenotyping site features an automated cable suspended carrier system that holds multiple cameras and sensors for positioning over plots.

[00:00:05.993]With this system, we can see what people cannot see
[00:00:10.553]by their naked eyes.
[00:00:12.478]We can do very accurate measurements and very fast.
[00:00:17.347]The system requires four different poles.
[00:00:19.334]The tensioning on the cables has to be adjusted
[00:00:22.889]based on where it's at in the field
[00:00:25.215]and so it shortens and lengthens each one of those cables,
[00:00:28.032]specifically to get to a specific location.
[00:00:30.872]We can do any crop we want
[00:00:33.278]because it can raise from ground level
[00:00:36.713]to nine meters above the ground.
[00:00:39.016]We can control within about,
[00:00:40.611]plus or minus, a centimeter of placing that camera
[00:00:45.207]in the same position each time,
[00:00:47.197]so therefore, it allows us to get images that are identical
[00:00:51.486]from one time to the next, in order to make comparisons.
[00:00:54.874]We have minimum shadow on it which is very important.
[00:00:58.009]With the large payloads,
[00:00:59.825]we can do a number of different instruments
[00:01:02.381]at the same time, as opposed to the drone,
[00:01:04.305]where you're limited by the payload capacity of the drone.
[00:01:07.594]This allows us to do different camera sytems
[00:01:11.358]and imaging at the same time, on the same plants.
[00:01:17.112]We have the very advanced subsurface irrigation system.
[00:01:22.022]We have 130 different
[00:01:23.651]individually-controlled irrigation zones out in that field.
[00:01:27.473]And, we can control independently for all of them.
[00:01:34.441]This is the first system in the United States.
[00:01:39.274]It will give us a lot of innovative way
[00:01:42.637]to develop our modern phenotyping pipeline.
