③ And calculating the height of the tree by using a trigonometric function calculation formula.
(2) Diagonal rod method
The diagonal rod method is a relatively accurate method for measuring the height of a tree, and the principle of the diagonal rod method is to measure the height of the tree according to the length and the angle of the diagonal rod by using a calculation formula of a trigonometric function.
① A diagonal is erected at a position far from the tree so as to be tangent with the top end of the tree, and the length of the diagonal and the inclination angle of the tree are measured.
② And calculating the height of the tree by using a trigonometric function calculation formula.
(3) Laser ranging method
The laser ranging method is an advanced method for measuring the height of the tree, and the height of the tree is measured by using a laser range finder.
① Standing at the bottom of the tree, aligning the laser rangefinder to the top of the tree, and pressing the measurement key.
② The laser rangefinder automatically measures the height of the tree.
