A whole-of-data comparison of automated height estimation and manual measurement.

<p>Manual measurements of canopy height for the field trial of 60 plots taken on four occasions are compared with the canopy height estimated using depth map estimation from stereo images. The solid line is the line of best fit to the data which, having a slope of 0.9973, is close to the ideal 45° line. Note that manual measurements as reported are the result of averages of several observations sampled across the plot, and therefore are prone to some degree of variation. Data points with different colors are from the four different days on 23/09/2016 (green squares), 27/09/2016 (yellow triangles), 11/10/2016 (blue diamonds) and 14/10/2016 (red circles).
