How it works:
The sowplan of the entire test field constituting all the plots must first be uploaded to the scanner. In this way the scanner “knows” all the plot names and their location in the test field.
When the driver enters a new track (a set of plots) he is being prompted by the scanner. This ensures that always the right plots are being recorded. The system also includes a set of markers to be placed in the test field. These markers are scanned by the camera and define the exact position of the plots. The markers are later identified by the software and allow a subsequent scanning of the same field at a later time to be correlated with the first scanning.
It is only necessary to place markers in one of the scanned tracks. If a machine is equipped with 8 cameras, markers need only to be placed at every 8th. row.
The normal driving speed is 3.5 – 4 km pr hour. At this speed the system resolution is 1.8 x 1.8mm.
When the field has been scanned, the hard disk from the scanner is connected to the server.
The server provides a simple user-interface for uploading the raw data from the hard disk of the scanner. The interface also provides information on the progress of the analysing of the data set.
While data are been processed, the finished files can be downloaded to a USB-key or accessed via LAN for transferring to a spreadsheet on your desktop computer.
Because of the large capacity of this scanner, it is possible to scan a test field with 10.000 parcels every second day. Therefore one can track the development of thousands of parcels with emerging plants very accurately.
The scanner is build on a frame carrying 2 – 8 cameras. The frame has 2 supporting wheels.
