Background

Trunk diameter refers to the diameter in a cross section perpendicular to the trunk axis, and is generally denoted as D or D. The diameter 1.3m from the root to the chest height is called the chest height Diameter (DBH), which is an important basic tree measuring factor in forest resource investigation, and the accuracy of the DBH directly affects the estimation of the volume and accumulation of trees.

The calipers are various in types and simple and varied in structure, and commonly include a girth ruler, a wheel ruler, a hook ruler, a multipurpose tree-measuring instrument and the like. Among them, the girth gauge and the wheel gauge (also called diameter caliper) have simple structure, and are well known by vast forestry investigators for measuring the diameter of trees. The girth ruler is not suitable for measuring trees with thorns and secretions, the wider ruler surface of the girth ruler can cause measurement errors, the larger trees need to be measured for many times and then accumulated with readings, and the measurement efficiency is greatly reduced. The traditional diameter caliper has two kinds of wood or aluminum alloy system, and nowadays, most adopt aluminum alloy system diameter caliper. Diameter caliper survey crew only needs to carry out the reading with both sides kelly interlock trunk when measuring, convenient operation, but the size of kelly and chi body is if the short then the range is little, if the overlength then the portability is poor.
