Background
In field operation, particularly in site and mining area measurement operation, shielding of tall buildings, trees and the like is often encountered, if the coordinates under the roof eave of building walls, galleries, hallways and the like need to be measured, the conventional GNSS measurement cannot complete the coordinate positioning of a to-be-measured point because satellite signals are shielded, so that the GNSS measurement in the current state, particularly the measurement of a large number of building groups, is always the subject of field measurement operation research.
The current situation measurement of the building area is carried out by adopting a total station in the past, when no GNSS assistance is carried out, the current situation measurement is carried out by taking the points on the wire network as the map and measuring the map by the points after the data adjustment, so that the current situation measurement of the building area can really enter the map measuring stage after the steps of on-site stepping, wire network arrangement, measurement adjustment and the like are needed. The more complex the building area, the denser and longer the wire mesh laid out with more shielding, which presents challenges for later data qualification resolution. The method is also a large number of station setting and rearview in the field measurement, and the data acquisition of one station is time-consuming and labor-consuming. The wire net layout method has been gradually replaced.
The GNSS cooperates with the total station to operate, so that the characteristics that the GNSS is not limited by the visibility and is free and flexible and the advantages that the total station is not shielded by satellite signals can be fully exerted, and the point acquired by the GNSS on site can be used as the following point of the image of the total station in the later stage.
With the development of satellite mapping, GNSS operation is becoming popular, and the method is flexible, free from influence of visibility, free from error accumulation and the like, and is widely applied to various industries. But at the same time, the biggest factor restricting the application of the method is satellite signals, namely shielding, and the more trees in the field and the higher buildings are, the more obvious the influence is. It is therefore necessary to find a device and a method that can solve the problem of performing hidden point measurements in the case of occlusion by a GNSS.
