Description

technical field [0001] The invention belongs to the technical field of geographic information, and in particular relates to an autonomous surveying and mapping machine. Background technique [0002] Market demand: There are thousands of applications in the geographic information industry stemming from 4 core needs [0003] 1) Obtain the three-dimensional geodetic coordinates of the target; [0004] 2) Obtain the topographic and feature map under the three-dimensional geodetic coordinates; [0005] 3) Obtain the 3D image of the object space under the 3D geodetic coordinates; [0006] 4) Obtain the 3D navigation map based on the 3D image in the geodetic coordinate system. [0007] Technical status: Multiple groups of personnel use a wide variety of multiple groups of instruments and equipment to obtain one of the above core requirements in different ways and form various applications. The existing limitations are low efficiency, time-consuming service, high cost, and limit...

AI Technical Summary

Problems solved by technology

Traditional equipment relies on manual operation, and the human errors and the errors introduced into the geodetic coordinates in segments are large and there is no effective error correction method

The efficiency of traditional equipment is very low, and obtaining a low-precision three-dimensional geodetic coordinate of the object space often requires a team of professional and technical personnel to work for a long time

It consumes a lot of manpower and time, and the actual work cost is high

[0012] 2) GPS locator: The instrument must be erected on the measured target for observation. This first requires that the measured target has the conditions for erecting the instrument. The target points of the measurement often do not have the conditions to set up the instrument

[0013] 3) Total station: It can only measure angles and distances in a custom coordinate system; it completely relies on manual operation, the human error is large and there is no effective error correction method; when measuring the three-dimensional coordinates of the object, it is necessary to have more than two Known control points; to determine the direction of true north, you must purchase the data of the local GPS control network (if such a network exists locally), or use a gyroscope; to introduce geodetic coordinates, you must use a GPS locator

[0024] 3) Movement and operation: The equipment that makes up the system is large in size and weight, and the system structure is loose. It must be fixed on a large carrier such as a car and operated by multiple people.

[0025] 4) The working method of field data collection and post-processing in the field leads to the unavoidable repetitive field labor

[0027] 6) Expensive: All the components of the mobile road measurement system are outsourced. The high price of these high-end equipment makes the cost of the "mobile road measurement system" high. The mobile road measurement system without laser ranging scanner (no measurement The price of the product is 4 million yuan / set; the price of foreign products with laser scanning distance measuring equipment is higher than 6 million yuan / set
