Table 2 Comparison of the error measurements for the leafmeter–laserscanner combination using different sampling resolutions for the laserscanned point cloud between 0.3 and 15 mm

From: Measuring crops in 3D: using geometry for plant phenotyping

  Resolution [mm] \(R^2\) MAPE % RMSE cm2
Leafmeter   0.99 0.16 5.01
Laserscanner 0.3 0.99 0.04 1.34
1.0 0.91 0.05 3.94
5.0 0.89 0.11 5.4
10.0 0.89 0.43 13.96
15.0 0.68 0.90 30.66
  1. Sampling included a reduction in resolution as well as adding noise in the same dimension. \(R^2\) error measurements are shown as well as a MAPE and RMSE calculation
