При выращивании рассады агроному постоянно приходится подсчитывать вручную количество взошедших растений в кассетах. Это трудоемко и утомительно. Голландцы создали аппликацию (мобильное приложение, applet), которая значительно облегчает эту работу. Игрушка недешевая, практически 100 евро, но интересная. Дальше читайте сами на английском, переводить некогда, да и боюсь в терминологии напутать.

TTA launches new “Trayscan” app

With the launch of TTA’s “Trayscan” app, plant handlers around the world can take the human hands and eyes out of counting germinated seeds. For €99.99, the app is now available on Google Play.



For decades on end, the plant handling sector has grappled with an intensive use of labour: the bare-handed, naked-eyed counting of germinated seeds. In the sector it is not uncommon for larger companies to have up to four employees counting produce, day in, day out.



“Today’s generation of smartphones and tablets carry extremely advanced cameras for their size,” said Bram Verschoor, Commercial Director at TTA. “Why not make use of the widely available smartphone and tablet technology to automate this counting process, rather than build a heavy-weight, importable machine? We are the industry’s first to launch an app of this kind and by doing so, simplify the counting process while making it more reliable.”

“Ever since we first heard of it, we hailed this innovative idea,” said Rudy Raes, owner at Rudy Raes Bloemzaden in Destelbergen, Belgium. “And our in-company tests have only confirmed our excitement. Our use of the Trayscan app has resulted in enormous reductions of labour.”



The app comes with a wide array of functionalities, two operational modes, and integrates TTA’s extensive experience with the development of vision applications in machinery. In the first mode, the operator enters a grid’s setup – length and width – and based on a picture taken exactly above a tray, the app calculates the tray’s germination rate.

“In the second mode,” Bram explained, “the operator sets out with a picture of a tray regardless of the angle from which it was taken. The app lets you correct for a picture’s mistaken angle with four simple clicks on the corners of the tray. Based on colour and pixel preferences, the app calculates a germination percentage. And thanks to the ability to adjust the colour intensity threshold used to assess germination, the app distinguishes between algae and actually germinated seeds.”



Capitalising on the sector’s use of barcodes and QR codes, the app is also able to scan a bar- or QR code, and tie all related information to this code. When finished, the information collected for a particular code can be shared as Excel spreadsheet that includes colour settings, pixel settings, and germination rates.
