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. These widely available smartphone and tablet technology is used to automate the counting process. TTA is 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 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.
