Strube and Bosch develop Deepfield 4D-scan


Innovation: World’s first high-performance field emergence scanner
Strube and Bosch develop „Deepfield 4D-scan“

Söllingen, 5 November 2015 – In a joint project, the seed company Strube and the Bosch start-up company Deepfield Robotics are developing the worldwide first self-navigating field emergence and seedling scanner for sugar beets. Strube will present a model of the scanner at Agritechnica (hall 25, stand H22) from 8 to 14 November 2015. Bosch Deepfield Robotics can be found at stand F02 in hall 9.

151106_Deepfield 4D-scanWith the „Deepfield 4D-scan“, it is now possible for the first time to perform an automatic daily assessment and image documentation of field emergence and plant development in sugar beet field tests. Field emergence speed, uniformity and rate, as well as possible plant losses and leaf development of individual seedlings can be measured over time (4D).

The announced performance of the mobile scanner system is a high throughput of 2.2 row kilometres per hour and the recording of an average 12,000 plants per hour. Strube uses the data collected to constantly optimise and stabilise seed quality and sugar yield.

Autonomous daily scans of test plots with various combined sensors determine the position of each emerged seedling and use 4D phenotyping to clas-sify it as weed or beet. Only plants classified as sugar beets are counted, their total leaf surface is measured and their development is documented over time. 3D leaf surface scans continuously monitor plant growth from emergence to 6-8-leaf stage.

The compact device can be transported on a trailer pulled by a passenger car, is very easy to operate and flexible in operation.
