Abstract

The invention discloses a tree size measurement device and method based on angular measurement, belonging to a measurement instrument and a measurement method, in particular to a measurement device and method used for measuring the tree height, the diameter at breast height and the diameter of the crown in any environment in the forest survey. The device comprises a horizontal scale, a vertical scale, a horizontal spindle, a fixing device and a measurement device, wherein the vertical scale horizontally slides along the upper surface of the horizontal scale; the horizontal spindle is configured on the top end of the vertical scale; the fixing device is connected with the top end of the horizontal spindle; the measurement device is connected with the fixing device; the vertical scale comprises a scale sleeve and a scale rod, wherein the scale rod can stretch in the scale sleeve along the vertical direction; the rotation plane of the horizontal spindle is a horizontal plane; the fixing device comprises a vertical spindle; and the rotation plane of the vertical spindle is vertical to the horizontal plane. With the method, the measurement can be finished with the cooperation of a trigonometric function with a four arithmetic operation, and therefore, the device and the method have the beneficial effects of convenience in measurement and low construction cost.

Description

technical field [0001] A tree size measuring device and method based on angle measurement belongs to measuring instruments and measuring methods, and is specifically used for the measuring device and method of tree height, diameter at breast height, and tree crown diameter in any environment in forests. Background technique [0002] As my country's forestry production has shifted from a production model dominated by tree harvesting to a forest closure model, the task of forest surveys has become heavier. The use of traditional survey methods and survey equipment cannot meet the needs of the work in terms of work efficiency and survey accuracy. The cost of laser rangefinder is too expensive, which limits its use. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a tree size measurement device and measurement method; the device and method are convenient for measurement and low in cost, and solve the problem of complex gro...
