Abstract

A seed imaging system for imaging seeds includes a seed transfer station configured to move seeds through the system. An imaging assembly includes a first camera mounted relative to the seed transfer station and configured to acquire images of the seeds as the seeds move through the system. A second camera is mounted relative to the seed transfer station and is configured to acquire images of the seeds as the seeds move through the system. The second camera has an imaging modality different from an imaging modality of the first camera. First and second cameras may be disposed above and below the seed transfer stations, such as a transparent belt.

First claim

What is claimed is:

1. A seed imaging system for imaging seeds, the system comprising:
a seed transfer station configured to move seeds through the system, the seed transfer station including a conveyor belt, wherein the seed transfer station is configured to substantially fix a position and/or orientation of each of the seeds on the conveyor belt as the seeds move through the system;
a tracking sensor configured to register the position and/or orientation of each of the seeds on the conveyor belt;
an imaging assembly comprising:
at least one first camera mounted relative to the conveyor belt of the seed transfer station and configured to acquire 2D images of the seeds as the seeds move through the system;
at least one second camera mounted relative to the conveyor belt of the seed transfer station and configured to acquire 3D images of the seeds as the seeds move through the system;
at least one third camera mounted relative to the conveyor belt of the seed transfer station and configured to acquire X-ray images of the seeds as the seeds move through the system; and
at least one fourth camera mounted relative to the conveyor belt of the seed transfer station and configured to acquire hyperspectral images of the seeds as the seeds move through the system;
wherein the 2D images, the 3D images, the X-ray images, and the hyperspectral images include images of each of the seeds in the substantially fixed position and/or orientation on the conveyor belt; and

a controller configured to: (i) align the 2D images, the 3D images, the X-ray images, and the hyperspectral images acquired for each of the seeds based, at least in part, on the substantially fixed position and/or orientation of each of the seeds registered by the tracking sensor and (ii) analyze the aligned images of the seeds for one or more characteristics.

2. The seed imaging system of claim 1 , wherein the conveyor belt is one of transparent or semi-transparent.

3. The seed imaging system of claim 1 , further comprising a weighing assembly located at an end of the conveyor belt of the seed transfer station and configured to weigh the seeds individually;
wherein the weighing assembly includes:
a funnel configured to receive the seeds from the end of the conveyor belt;
a scale disposed adjacent an outlet of the funnel, the scale configured to receive an individual one of the seeds from the funnel and weigh the individual seed; and
a transport mechanism configured to transport the weighed seed away from the scale.

4. The seed imaging system of claim 1 , further comprising a storage assembly configured to automatically store the seeds into separate storage containers based on the analysis of the images of the seeds by the controller.

5. A method of imaging seeds, the method comprising:
aligning individual seeds in at least one row at a seed loading assembly;
delivering the individual seeds, in the at least one row, from the seed loading assembly to a conveyor belt of a seed transfer station;
registering, via a tracking sensor, a position and/or orientation of each of the individual seeds delivered to the conveyor belt;
moving the seeds through a seed imaging system, in the at least one row, using the conveyor belt of the seed transfer station, wherein a position and/or orientation of each of the seeds is substantially fixed on the conveyor belt as the seeds move past a first camera and a second camera of the seed imaging system;
acquiring, using the first camera mounted relative to the conveyor belt of the seed transfer station, images of the seeds as the seeds move through the system via the conveyor belt;
acquiring, using the second camera mounted relative to the conveyor belt of the seed transfer station, images of the seeds as the seeds move through the system via the conveyor belt, an imaging technology of the second camera being different from an imaging technology of the first camera; and
aligning, by a controller, the images of the seeds from the first camera and the images of the seeds from the second camera based, at least in part, on the registered position and/or orientation of each of the seeds.

6. The method of claim 5 , further comprising analyzing the aligned images using the controller.

7. The method of claim 5 , further comprising acquiring, using a third camera mounted relative to the conveyor belt of the seed transfer station, images of the seeds as the seeds move through the system via the conveyor belt, an imaging technology of the third camera being different from the imaging technology of each of the first and second cameras.

8. The method of claim 7 , further comprising acquiring, using a fourth camera mounted relative to the conveyor belt of the seed transfer station, images of the seeds as the seeds move through the system via the conveyor belt, an imaging technology of the fourth camera being different from the imaging technology of each of the first, second, and third cameras.

9. The method of claim 5 , wherein the imaging technology of the first camera is one of 2D imaging, 3D imaging, X-ray imaging, and hyperspectral imaging; and
wherein the imaging technology of the second camera is a different one of 2D imaging, 3D imaging, X-ray imaging, and hyperspectral imaging.

10. The method of claim 5 , further comprising:
receiving individual ones of the seeds, from the conveyor belt of the seed transfer station, on a scale of a weighing assembly;
weighing the individual seeds received on the scale of the weighing assembly; and then
transporting the individual weighed seeds from the scale to a storage assembly.

11. The method of claim 5 , further comprising storing the seeds using a storage assembly.

12. The method of claim 11 , wherein storing the seeds comprising storing the seeds individually in microplates.

13. A seed imaging system for imaging seeds, the system comprising:
a seed transfer station configured to move seeds through the system;
a seed loading station configured to deliver the seeds to the seed transfer station;
a tracking sensor disposed at the seed loading station, the tracking sensor configured to register a position and/or orientation of each of the seeds delivered to the seed transfer station; and
an imaging assembly comprising a first camera mounted above the seed transfer station and configured to acquire images of the seeds as the seeds move through the system, and a second camera mounted below the seed transfer station and configured to acquire images of the seeds as the seeds move through the system;
wherein the transfer station is configured to substantially fix the position and/or orientation of the seeds in the seed transfer station as the seeds move past at least the first and second cameras.

14. The seed imaging system of claim 13 , wherein the first and second cameras have the same imaging modality.

15. The seed imaging system of claim 14 , wherein the imaging modality of the first and second cameras is one of 2D imaging, 3D imaging, X-ray imaging, and hyperspectral imaging.

16. A seed imaging system for imaging seeds, the system comprising:
a seed loading station configured to align seeds in at least one row;
a seed transfer station configured to receive the aligned seeds from the seed loading station and move the aligned seeds, in the at least one row, through the system;
a tracking sensor disposed at the seed loading station, the tracking sensor configured to register a position and/or orientation of the aligned seeds received at the seed transfer station; and
an imaging assembly comprising a first camera configured to acquire images of the seeds as
