Abstract

Abstract:

This research develops an integration of field and in-door-work system on volume measurement based on the theories of forest mensuration,image processing and sensor technology.The system consists of a portable super station and self-developed and post-processing platform.The azimuth angles,dip angles and standing tree images are acquired during measurement.Those data can be processed simultaneously to the post-processing platform to generate standing tree volume,and the results are automatically saved,which achieves the vision of integration of internal and external work.The measurement accuracy of the system was verified.The results show that the average accuracy of this system is 94.4%,and it can solve the problem of investigation difficulty in some forest areas.This system is convenient and portable,which is a beneficial attempt to improve the precision and intelligence of volume measurement.

Key words: data collection and processing, integration of field and in-door work, portable super station, volume measurement, standing tree volume
