Embodiment 1

[0045] The application of the prefabricated component finished product quality inspection system based on three-dimensional stereo vision in the device. The detection device includes a transport tool 1, a control box 2, a transport tool docking sensor 3, a component sensing module with infrared rays on both sides 4, and a binocular vision camera 5 , Suspension component 6, wrong parts area 7, bad parts area 8, component storage area 9, the control box 2 is equipped with a master control module, an image processing module and a network communication module, which are used to manually control the work of the entire quality inspection system Start and stop. Including the necessary work start and stop buttons when the quality inspection system is integrated with the aerial crane system as an independent system, it also includes some hardware equipment required by the entire quality inspection system, such as video transmission lines, image processors, development boards and process...

Embodiment 2

[0049] When the prefabricated component finished product quality inspection system based on three-dimensional stereo vision is integrated with the aerial crane system, it is used as an independent system for the detection method of prefabricated component quality inspection:

[0050] Step 1. After the 3D stereo vision prefabricated component quality inspection system receives the start work instruction (that is, manually starts the start button), the master control module will first conduct a self-inspection of the system under the control of the master control module in the quality inspection system to determine Whether the system can work normally, if the system can not work normally, it will transmit the failure instruction through the network communication module, and the quality inspection system will send out an alarm prompt to remind the on-site staff that there is a problem with the quality inspection system.

[0051] Step 2. If the self-inspection of the system is norm...

Embodiment 3

[0060] When the prefabricated component finished product quality inspection system based on 3D stereo vision is used as a subsystem in the component storage and transfer system, the working relationship with other systems, and the detection method used for prefabricated component quality inspection:

[0061] In the process of processing a transshipment order, after the manager edits the transshipment order on the mobile terminal, he releases the order to the component integrated management and control system, which will simultaneously provide component transfer subsystem, warehousing and crane subsystem and 3D stereo vision The prefabricated component finished product appearance quality inspection subsystem sends the transfer order, and at the same time, the component integrated control system sends the prefabricated component structural model to the prefabricated component finished product appearance quality inspection subsystem with 3D stereo vision. After the component trans...

Abstract

The invention discloses a prefabricated part finished product quality detection system based on three-dimensional vision and application of the system, and relates to the field of prefabricated part quality detection. A general control module is connected with an image acquisition module, an image processing module, a transportation tool parking sensing module, a part space sensing module and a network communication module; the general control module is responsible for comprehensive control and information interaction of all functional modules in the prefabricated part finished product appearance quality detection system based on three-dimensional vision and command and control of an overall hardware platform; a hardware part of the image acquisition module mainly comprises a binocular vision camera and a video transmission line of a component quality detection point; the image processing module detects prefabricated part model matching and prefabricated part appearance damage; the component space sensing module comprises an infrared detector for monitoring whether the prefabricated part to be subjected to quality inspection reaches a component quality detection point or not. Not only is an accurate and efficient quality inspection detection means provided, but also a basis is provided for inventory logistics of prefabricated part production enterprises and decision judgment of construction site engineering management personnel.

Description

technical field [0001] The invention relates to the field of quality inspection of prefabricated components, in particular to a three-dimensional stereo vision-based quality inspection system for finished prefabricated components and its application. Background technique [0002] Prefabricated buildings sprouted in the early 20th century, and gradually began to be widely used in many construction fields such as industrial buildings, roads and bridges, and water conservancy projects at the end of the 20th century. After the 1990s, the research and application of prefabricated building technology in my country started and developed rapidly. Compared with traditional cast-in-place concrete buildings, the core change of prefabricated buildings is that the main body of the building adopts a modular assembly structure, and the concrete prefabricated components are produced through the production method of mass production in the workshop. Prefabricated components such as wall pane...
