Laser scanning accuracy for tree diameter estimation improved by new bias compensation method

By PulseAugur Editorial · [1 sources] ·

A new study published on arXiv investigates the impact of laser beam width and measurement noise on the accuracy of tree diameter estimation using laser scanning. Researchers found that the heteroscedasticity of measurement noise and the lidar beam width cause estimation bias that depends on both distance and tree diameter. They developed a method to predict and negate this bias for trees larger than 10 cm in diameter, reducing root-mean-square error to sub-centimeter levels. However, the method's precision is limited for smaller trees due to increased sensitivity to unknown factors like bark texture and stem shape. AI
