Abstract

The invention relates to a super sound and laser system for measuring three dimensional space and uses thereof, which comprises: a computer, a transversal rail constructed across the tested river, a laser range finder fixed on one end of the transversal rail, a step motor fixed on the other end of the transversal rail, and a testing car which can slide on the transversal rail, wherein the step motor uses cable to drive the testing car to slide transversally on the transversal rail; the testing car incorporates an up-and-down sliding super sound sensor lifter, one end of the lifter is immerged into the river and incorporates a super sound sensor probe; the super sound sensor is on the middle part of the super sound sensor lifter; the super sound sensor probe above and below the river, the step motor and the laser range finder are separately connected with the computer.

Description

technical field [0001] The invention relates to a system for measuring three-dimensional space, in particular to an ultrasonic and laser system for measuring the three-dimensional topography of a river bed with water. Background technique [0002] As early as the 1960s, some colleges and universities and research institutes at home and abroad have combined the advanced photoelectric technology at that time to carry out the research and development of river engineering model topographic measuring instruments. The technical routes adopted include resistive, ultrasonic, photoelectric Radiation and laser etc. These methods deviate from the manual point-by-point measurement in the measurement method, and adopt the measurement method of tracking the terrain along the section, which improves the measurement speed and accuracy. The disadvantage is that these measurement methods are still contact measurements, which cause certain damage to the terrain and affect subsequent experimen...
