Abstract:Based on the principle of photogrammetry, image-processing technology and forest measurement, the forest telescope intelligent dendrometer composed of PDA module, remote EDM module, telephoto lens CCD and rotational station was developed to obtain the parameters such as inclination angle, azimuth angle, remote distance and image information. By using Java language and developing in Android Studio 2.1 systems development environment, the functions such as tree height measuring module, DBH measuring module, micro-sample plot measuring and basic measurement can be achieved. Verified by experiments, the measuring accuracy of tree height was as high as 93.32%, DBH was as high as 96.49%, stand average height was as high as 94.47%, stand average DBH was as high as 91.68%, stand density was as high as 86.04%, and that of stand volume measurement was 82.64%. It showed that the equipment can solve problems such as observation difficulties of non-arrival points and measurement difficulties of visible factors. Therefore, it can be used and promoted in the forestry inventory in the future.
Keywords:forest telescope intelligent dendrometer  forest-survey  Android development  design  experiment
