摘要:

以测树学、图像处理技术和传感器技术原理为理论基础,研发了一种单木材积内外业一体化测量系统。系统由便携式测树超站仪和内置自主开发的数据后处理程序组成,测量时通过获取方位角、倾角及单木 影像信息等参数,结合数据后处理程序进行单木材积计算生成结果,实现了便携式测树超站仪内外业一体化的构想。对系统的测量精度进行了验证,结果显示,该系统平均精度高达94.4%,能较好地满足单木材积测量的要求,可以解决部分林区因调查难度高无法测量材积的问题。此外,该系统便捷且高效,是单木材积测量精准化与智能化的有益尝试。

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
