Tree value and log product yield determination in radiata pine (Pinus radiata) plantations in Australia: comparisons of terrestrial laser scanning with a forest inventory system and manual measurements

摘要: New sensor-based approaches for assessing the quantity, quality, and value of timber are being developed with goals improving accuracy economics forest measurements. One new approach is based on terrestrial laser scanning (TLS). Thirty-three plots in six radiata pine (Pinus D. Don) stands were scanned using TLS. Tree locations automatically detected. Stem profiles measured three methods: (i) TLS scans, (ii) Atlas Cruiser inventory procedures, (iii) manual measurement after harvesting. Stems optimally bucked log specifications prices Australian markets. values product yields estimated data compared estimates actual measurements stem profiles. volume recovery within 8% 7%, respectively, harvester five which it was used. both 4% recovery.
