Problems solved by technology
[0002] Urban construction inevitably involves earth and stone work, but construction excavation in areas densely covered with municipal pipe networks is very easy to cause regional accidents due to accidental damage to underground pipelines
On the other hand, when the underground pipeline network needs to be repaired, due to the intricate underground pipeline systems of many municipal departments (water, electricity, gas, heat), during the underground construction process, the positioning of urban underground pipelines is very important for construction units and workers. A huge challenge. Even if part of the pipeline has been surveyed and mapped, and there are drawings, it is still difficult to observe and understand. Even if the location of the pipeline is known, how to accurately control the machinery when operating the excavation machinery is also a problem

Embodiment 1
[0068] (1) Locate its own position and display the three-dimensional municipal pipe network in the AR device.
[0069] (2) An inertial sensor is installed on the excavating equipment so as to know the current position of the cantilever of the excavating equipment. Preferably, inertial sensors may be mounted at the mechanical joints.
[0070] (3) Use the attitude control system to convey the movement attitude to the system through the excavation equipment.
[0071] Start the system and all sensors, adjust the cantilever to an agreed position (such as extending all joints to the level or bending all joints 90 degrees clockwise) to initialize the system. At this time, the system will record the current attitude and the position of the sensor, which is defined as 0 point. For example, define the initial position of the excavator as (X 0 , Y 0 ,Z 0 ), the initial position of the first joint point is (X 1 , Y 1 ,Z 1 ), the initial position of the nth joint point is (X n , Y...

The present invention relates to an excavating auxiliary method based on an augmented reality technology. The method comprises the steps of: performing location of an excavating device; transferring athree-dimensional municipal pipe network based on AR near the location position; collecting the attribute of the excavating device and calculating the relative position of an underground pipe networkbased on the three-dimensional municipal pipe network based on AR. The present invention further relates to an excavating auxiliary system based on the augmented reality technology.
