Integral type survey and drawing reflex assembly

Technical Field

The application relates to the field of surveying and mapping, in particular to an integrated surveying and mapping reflecting device.

Background

In the field of surveying, total stations are commonly used for engineering measurements, including measurements of distances, angles, three-dimensional coordinates, wires, etc. The total station is a short for total station type electronic tacheometer, and is a photoelectric instrument combining an electronic theodolite, a photoelectric distance meter and a microprocessor. When distance measurement is carried out, the total station needs to be aimed at the center of the reflecting prism, and a distance value is obtained by transmitting and receiving signals. With the rapid development of lidar technology in recent decades, many engineering measurements are now being measured using laser scanners. A laser scanner is an apparatus that obtains three-dimensional environmental information by emitting and receiving laser light reflected by a target object. Compared with a total station, the measuring density is high, the speed is high, and a reflecting prism is not needed to reflect signals, so that more and more attention is paid. However, due to the scattering and disordering of the laser radar point cloud, the reliability and the precision of the point cloud data acquired by the laser radar are low. Due to the influence of the integration error of the laser radar system, accumulated errors usually occur in the data acquisition process, so that large-range point cloud data needs to be acquired by being divided into different batches, and then complete data can be acquired through further processing (such as registration, adjustment and the like). Therefore, total stations and lidar scanners have advantages and disadvantages.

In actual engineering measurement, the two are usually combined, a laser radar scanner is used for acquiring complete three-dimensional environment information, and then a reflecting prism is erected in a proper area, the reflecting prism is installed on a centering rod through a prism rod, and the centering rod is installed on the ground, so that erection of the reflecting prism is realized. The reflection prism reflects the mapping light, the mapping light reflected by the reflection prism is scanned and received through the total station, so that accurate point location information is obtained, the information is utilized to assist the registration of the laser radar point cloud, accumulated errors are eliminated, and high-precision point cloud data are obtained. This operation generally comprises the following steps: firstly, a reflector plate is arranged in a measurement area, and a laser scanner is used for scanning to obtain point cloud data; and then finding a reflector plate area in the data area, erecting a reflecting prism again at the position of the reflector plate area, and measuring by using a total station to obtain high-precision point positioning data. And finally, the point cloud data is assisted to be registered by using the point data of the total station, so that the average precision of the point cloud data is improved, and the quality of the point cloud data is improved.

However, in the existing mapping, the arrangement of the reflecting prisms and the reflecting sheets is separated, and it is difficult to ensure that the relative position relationship between different groups of reflecting prisms and reflecting sheets is consistent, which also causes a certain error in the measuring method. In addition, the measuring method needs to find a reflector region in the point cloud data and arrange a reflecting prism, the work flow is complex, the workload is huge when multipoint measurement is needed, and additional errors are introduced in the complex operation steps.

SUMMERY OF THE UTILITY MODEL
