利用南方测绘公司的S352型号的全站仪和Vertex IV测高仪对8株针叶树从3个不同方位分别进行多次测量。结果表明：测高仪与S352型号的全站仪所测的树高均值相一致,测高仪测得的总平均树高相对于全站仪的相对误差都小于1.07%。并且应用Vertex IV测高仪测定的树高值的均方根误差都小于0.134m,说明测得的高度数据波动不大,然而全站仪的均方根误差较Vertex IV测高仪更小,稳定性更好。
利用南方測繪公司的S352型號的全站儀和Vertex IV測高儀對8株針葉樹從3箇不同方位分彆進行多次測量。結果錶明：測高儀與S352型號的全站儀所測的樹高均值相一緻,測高儀測得的總平均樹高相對于全站儀的相對誤差都小于1.07%。併且應用Vertex IV測高儀測定的樹高值的均方根誤差都小于0.134m,說明測得的高度數據波動不大,然而全站儀的均方根誤差較Vertex IV測高儀更小,穩定性更好。

S352 Total Station made by Southern mapping company and Vertex IV Altimeter were used in this paper to measure eight coniferous trees from three directions.Result shows that the average tree height measured by total station is consistent with that measured by Vertex IV Altimeter.The relative error of total average tree height measured by Vertex IV Altimeter with total station is less than 1.07%.The RMSE（root mean square error）is less than 0.134m when measured by Vertex IV Altimeter,indicating that the tree height measured by Vertex IV Altimeter is stable.However,the RMSE measured by the total station is much smaller,with better stability.
