Laserscanning accuracy—reference experiment using a photogrammetric method as reference to evaluate the accuracy of the Laserscanning device and the Leafmeter as a device for measuring leaf area [35, 36]. Both methods show a high correlation compared to the reference method (a). The comparison between the laser scanner using different point resolutions and the introduced reference method is visualized in addition (b). The transparent color in both plots indicates the confidence intervals (95%). The black line describes the bisecting line of the angle as the line of highest correlation
