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...
