Problems solved by technology

For example, if you use a level to measure terrain, when measuring complex terrain, you need to measure hundreds of points, which is time-consuming and laborious to use, and the level measurement accuracy is difficult to guarantee; if you use a total station to measure terrain, although the total station has high measurement accuracy, But the price is high, and it also needs to manually move the measurement points many times, which is very inconvenient to use; if the ground 3D laser scanner is used, although the accuracy can meet the requirements, it is very expensive and not suitable for large-scale use

Abstract

The invention discloses a model test topographic survey device, which is characterized in that a light emitter rotates downwards due to gravity, and after the light emitter rotates to the lowest point, a first circuit connector is connected with a second circuit connector. Therefore, a vertical rotating motor and a horizontal rotating motor are connected, a shell rotates horizontally, and the light emitter rotates upwards. Then the light emitter rotates upwards to the end to connect the first circuit connector with a third circuit connector, so that the horizontal rotating motor is switched on, the shell is rotated, then the light emitter rotates downwards due to the action of gravity, and the above steps are repeated until 360-degree irradiation to the surrounding is completed. The automation degree is high, automation is achieved through a mechanical structure, three-dimensional measurement is completed, the cost is low, the precision is high, and the use is convenient.

Description

technical field [0001] The invention relates to the field of terrain measurement, in particular to a model test terrain measurement device and method. Background technique [0002] When studying the river bed evolution of sand-laden rivers where bed surface deformation can occur, it is one of the important means to conduct dynamic bed river engineering model tests. In this model test, we need to map the shape of the river bed after the river scours, which is used to determine the actual impact of the river on the river bed. Therefore it is very important to measure the topography of the test model. [0003] There are various types of existing topographic measuring instruments, including levels, total stations, and ground three-dimensional laser scanners. There are still more problems. For example, if you use a level to measure terrain, when measuring complex terrain, you need to measure hundreds of points, which is time-consuming and laborious to use, and the level measur...
