Problems solved by technology

However, in this measurement method, it is necessary to build a truss guide rail above the object to be measured, which will undoubtedly greatly increase the cost of obtaining data such as the volume and quality of the predicted object, and sometimes the truss guide rail must be removed after the data is known, resulting in measurement great inconvenience

Abstract

The invention discloses a measuring device. The measuring device mainly comprises a main control unit, a measuring rod and a measuring unit installed on the measuring rod. The measuring unit comprises a distance measuring module, a first motor and a second motor, the first motor drives the distance measuring module to rotate, the second motor drives the first motor to rotate, and the main control unit controls the first motor and the second motor to rotate and collects and processes data measured by the distance measuring module. A measuring method is further provided. The measuring device can conveniently detect the three-dimensional contour of a predicted object, is subject to less influence of distribution conditions, the size and the shape of the predicted object and is simple in structure, convenient to dismantle and install, very suitable for learning about the three-dimensional contour of a large accumulation object and particularly suitable for a temporarily placed accumulation object.

Description

technical field [0001] The invention belongs to the field of measuring equipment, in particular, it is used to measure the three-dimensional profile of a large range of objects, and in particular relates to a measuring device and a measuring method using the measuring device. Background technique [0002] Three-dimensional measurement can generate the three-dimensional outline of the item, and then can know its overall shape, and can easily know the volume of the item, and then get the weight and other data. Some accumulations are piled up randomly and have extremely irregular shapes, such as grain piled in the granary, sand placed on the ground, etc. When trying to obtain the volume or weight of these objects, it is often obtained through the initial record It is known that if there is a problem with the recorded data, it is difficult to get the real situation. [0003] Most of the existing measurement methods are to place a vertical truss guide rail above the accumulation...
