Abstract: This paper is about designing a portable leaf area meter using Beagle board single board computer and a line scan image sensor. A leaf area meter is a device used by agriculture scientists as well as in agriculture industry to measure the area of leaves.

The goal of this project is to design a portable system more like a hand held scanner that can be used to scan a leaf and get a measurement of its area, size and shape and optionally diseased areas also. The system will be designed around a beagle board single board computer interfaced to a line scan image sensor and also a LCD/LED display panel and a touch keypad. The system will be handheld or dockable to a portable conveyor. Results will be stored on-board or can be transferred via optionally wireless mode to a desktop machine.
