Terrain data collection device and data collection method based on river work dynamic bed model

Abstract

The invention discloses a terrain data collection device and a data collection method based on a river work dynamic bed model. The device comprises a support, a data acquisition system, a computer and a power supply, wherein the support comprises two panels and two mutually parallel rail beams; the data acquisition system comprises a translation device, a terrain profile acquisition device and an image collection and correction device; the translation device comprises a bearing platform, a lifting motor, a traction motor and a counter weight; the terrain profile acquisition device comprises an upper stable plate, a lower stable plate, a synchronous motor, an electronic cloud platform and a line laser; and the image collection and correction device comprises a framework, a camera, a universal rod and a point laser. The terrain data collection device based on the river work dynamic bed model has the beneficial effects that the collected terrain image information is rich and intuitive, and is easy to store and update; point-group-type collection is carried out on the terrain surface information, thus the measuring efficiency is improved greatly; the measuring belongs to non-contact-type measuring which can avoid the damage of the measuring terrain form and is suitable for measurement of terrains under various conditions; and the device provided by the invention is simple in structure, low in cost and easy to popularize.

Description

Technical field [0001] The present invention involves the field data collection field of the Model Model Model Model, and specifically involves a root data collection device and data collection method that can observe the surface shape of the riverbed surface. Background technique [0002] After the study of bridges and dams such as bridges and dams in natural situations or rivers, there are two methods for the water and sand movement of the river and the evolution of the riverbed: river work model and mathematical model.Jiao Aiping and others discussed the relationship between the two methods (Jiao Aiping, Zhang Yaoxian, the relationship between the physics model of the river industry and the muddy mathematical model [J]. People's Yellow River, 2002,24 (7): 17+23.).The use of mathematical models to study water and sand problems has the characteristics of short cycles and less investment. With the rapid development of computer technology and the continuous improvement of sandy ma...
