Background
With the continuous development of GPS, GALILEO, GLONASS and China Beidou navigation and positioning systems, the GPS receiver based on multiple satellites is widely applied to mapping. Although widely used in field mapping, GPS receivers have historically determined that they cannot be used in locations where GPS satellite signals are obscured or where the signal quality is poor. In actual field surveying and mapping production, a surveyor can only use a total station to measure a hidden point without a GPS satellite signal (such as under a forest or under a building), so that the surveyor needs to carry two devices (a GPS receiver and the total station) and switch between two different surveying instruments and technical routes.
The distance measuring instrument is also a commonly used measuring instrument in the surveying and mapping industry, has a simple structure, is low in price, and is widely applied to distance measurement, particularly indoor distance measurement, but the distance measuring instrument has a relatively single function, and is usually used as an independent measuring tool for distance measurement.
However, the use of the distance meter and the GPS receiver has practical significance (i.e. the coordinates of the hidden point are solved by positioning and measuring the spatial positions of four groups of points and measuring the linear distance between four points to be looked at and hidden points are looked at), but how to fix the distance meter and adjust the direction are always difficult because the measuring personnel needs to fix the starting point position of the distance meter, fix the direction to be looked at and record data, and the ideal effect is difficult to achieve by manual lifting, thereby reducing the measurement precision.
Therefore, the invention requires an improved technology and a closely related technical status.
