The invention provides an accurate control system for tunnel excavation of an excavator based on BIM (Building Information Modeling) and machine vision. The accurate control system for tunnel excavation of the excavator based on BIM and machine vision comprises a multi-line laser radar for acquiring tunnel field excavation section information, a binocular camera for acquiring tunnel field environment image information, and a ZigBee wireless module used for wirelessly transmitting the tunnel field excavation section information and the tunnel field environment image information to a central control computer, wherein the central control computer performs fusion modeling by utilizing the tunnel field excavation section information and the tunnel field environment image information to form an actually measured section model which is automatically compared with an existing BIM tunnel model; the comparison result is transmitted back to a display device in a cab of the excavator so as to be displayed; and an alarm device in the cab is triggered to give an alarm when the over-excavation and under-excavation phenomena occur according to the comparison result. According to the accurate control system for tunnel excavation of the excavator based on BIM and machine vision provided by the invention, advanced technologies such as a building information model and a laser radar in the engineering construction field are combined, so that intelligent control over tunnel excavation of the excavator is achieved, the excavation precision is improved, the reaction time is shortened, and over-excavation and under-excavation are effectively controlled.
Description
technical field [0001] The invention relates to the field of BIM technology and excavator tunnel construction, in particular to a precise control system for excavator tunnel excavation based on BIM and machine vision. Background technique [0002] BIM (Building Information Modeling, Building Information Modeling) is a three-dimensional database that integrates all kinds of relevant information in the life cycle of construction projects. The BIM model simulates the entity and functional characteristics of engineering project facilities through three-dimensional digital technology, which is easy to apply to design, Construction and management of various processes can improve the efficiency of construction project management and greatly reduce construction risks. [0003] As an important technical means for the development of construction industry informatization, BIM technology has played an active role in the optimization design and collision inspection of housing constructio...
