Terrestrial Laser Scanning in Phenotyping.

Plant growth performance is an essential trait of many crops especially if its investigated in close relation to climate data. Therefore different methods for canopy height measurements were already developed. UAV and phenomobile based methods allow for flexible monitoring of large areas with cm accuracy. The achieved resolution is sufficient to , accurately distinguish canopy heights of different genotypes or treatments but generally fails at determination of growth rates in the time range of a week. Our presented combination of terrestrial laser scanning combined with stationary markers allows for a precise determination of crop heights which enables the determination of growth rates over a week and therefore gives a valuable tool for plant breeding.
