Embodiment 1

[0051] This embodiment provides a height measuring device 100, which includes a height measuring mechanism 10 and a plumb mechanism 11,

[0052] The height measuring mechanism 10 includes a light emitter 101, an angle measurement module 102, a distance measurement module 103 and a calculation module 104. The light emitter 101 is configured to emit measurement light, and the angle measurement module 102 is configured to measure the distance between the light and the horizontal plane. and transmit the angle information to the calculation module 104, the distance measurement module 103 is configured to measure the distance information between the target and the light emitter 101 and transmit the distance information to the calculation module 104, the calculation module 104 It is set to calculate the height of the target object according to the angle information and distance information;

[0053] The plumb mechanism 11 and the light emitter 101 are connected to each other, and the...

Embodiment 2

[0068] Please refer to figure 2 , the present embodiment provides a kind of altimetry method, and this method comprises the following steps:

[0069] Angle measurement: use the light emitter 101 and the plumb mechanism 11 to measure the horizontal elevation angle α at the top of the target and the horizontal depression angle β at the bottom of the target at the preset height position;

[0070] Ranging: use the light emitter 101 to measure the distance q between the light emitter 101 and the preset target point and the horizontal angle θ during ranging, and after the distance q and the horizontal angle θ are transmitted to the calculation module 104, pass The calculation module 104 obtains the distance information Q between the light emitter 101 and the target;

[0071] Height measurement: through the calculation module 104, the height H of the target object is obtained according to the horizontal elevation angle α, the horizontal depression angle β and the distance informati...

Abstract

The invention provides a height measuring device and method, and relates to the technical field of measurement. The height measuring device comprises a height measuring mechanism and a plumb bob mechanism. The height measurement mechanism comprises a light emitter, an angle measurement module, a distance measurement module and a calculation module, the light emitter is used for emitting measurement light, and the angle measurement module is used for measuring information of an included angle between the light and the horizontal plane and transmitting the information of the included angle to the calculation module; the distance measurement module is used for measuring distance information between the target object and the light emitter and transmitting the distance information to the calculation module, and the calculation module is used for calculating the height of the target object according to the included angle information and the distance information. The plumb bob mechanism and the light emitter are connected with each other. The height measuring device can calculate the height of the target object by measuring the included angle information and the distance information, is not limited by any topographic condition, is high in precision, and can greatly reduce the labor intensity. The method is applied to the device and has all the beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of surveying, in particular to a height measuring device and method. Background technique [0002] Forest resources monitoring is the work of observing, analyzing and evaluating the quantity, quality, spatial distribution and utilization status of forest resources on a regular basis. It is the basic work of forest resources management and supervision. Its purpose is to keep abreast of the current situation of forest resources and the dynamics of growth and decline, predict the development trend of forest resources, and serve for scientific decision-making of forestry management. An important index in forest resource monitoring is the measurement of trees, and the measurement of trees basically revolves around measurement factors such as height measurement and diameter measurement. [0003] At present, the method of measuring the height of trees is mainly to use the Brules altimeter. This method of ...
