Embodiment 1

[0042] see Figure 1~Figure 3 , the embedded parts inspection system of this PC component production line, including: image acquisition room 1, two camera vibration reduction devices 2, RFID fixed reader 3, track 4, PC mold 5, RFID tag 6, steel cage 7, Computer 8, six LED supplementary light sources 9, camera rail 10, two cameras 11 and photoelectric switch 12. The embedded part 13 to be tested is located inside the steel cage 7, the steel cage 7 is located inside the PC mold 5, and the RFID tag 6 is fixed on the outside of the PC mold 5; the PC mold 5 is slid on the track 4, and the track 4 passes through the image acquisition room 1; The RFID fixed reader 3 is placed in the middle of the image collection room 1 and is at the same height as the RFID tag 6. The photoelectric switch 12 is placed at the front end of the image collection room 1 and is at the same height as the PC mold 5. Six LED supplementary light sources 9 are distributed At the middle and top corners of both ...

Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, and the features are as follows:

[0045] In the embedded parts detection system of the PC component production line, the six LED supplementary light sources 9 are placed in the middle and top corners of both sides of the image acquisition room 1, and the position arrangement ensures that the light in the image acquisition room 1 is sufficient and evenly distributed. The LED supplementary light source 9 is used as a supplementary light source when the camera 11 collects images. The photoelectric switch 12 is arranged at the bottom position of the image acquisition chamber 1, and is at the same height as the PC mold 5, and the placement position ensures that when the PC mold 5 enters the image acquisition chamber 1 as a whole, two cameras 11 are started to collect images.

[0046] The camera guide rail 10 is placed in the middle of the top of the image acquisition chamber 1, and the two camera vibration reduction dev...

Embodiment 3

[0049] see Figure 1~Figure 6 , the embedded parts detection system and method of this PC component production line, adopt the above-mentioned system to operate, and the specific operation steps are as follows:

[0050] 1) Image acquisition

[0051] Two cameras 11 positioned at the top of the image acquisition chamber 1 carry out image acquisition to the PC mold 5 at the same time, and obtain two images of the PC mold 5;

[0052] 2) Image stitching

[0053] Project the images of the PC mold 5 obtained in step 1 into a unified coordinate system, and use the nonlinear least squares method to optimize to obtain the image stitching transformation matrix, and stitch the overlapping areas of the two images to form a complete PC Die 5 panorama image;

[0054] 3) Establish a PC mold library with embedded parts

[0055] Establish a PC mold library containing embedded parts, and at the same time establish a corresponding relationship between the PC mold library containing embedded p...

Abstract

The invention discloses an embedded part detection system and method for a PC member production line. The system comprises a hardware auxiliary system and an image detection system. The hardware auxiliary system comprises an image collecting chamber, a camera vibration damper, an RFID fixed reader-writer, a track, a PC mold, an RFID label, a steel reinforcement cage, an LED supplement light source, a camera guide rail, a camera, a photoelectric switch and a computer. The image detection system comprises an image acquisition module, an image splicing module, a detection statistics module and a PC mold map depot containing embedded parts. By means of the embedded part detection system and method, real-time on-line detection, which includes the detection whether the embedded parts are put or not and the detection of the put embedded parts, of the types of the embedded parts on the PC member production line is achieved, efficiency of detecting the types of the embedded parts is improved, and potential safety hazards caused by traditional artificial detection to later construction are avoided.

Description

technical field [0001] The invention relates to a detection system and method for a production line, in particular to a detection system and method for embedded parts of a PC component production line. Background technique [0002] With the continuous increase of social population, people's demand for housing construction is also increasing. The traditional housing construction cycle is long, the project volume is large, and it faces many problems. One of the major problems that needs to be solved is the rapid construction of housing. With the rapid development of modern technology, the PC component production line provides the possibility to solve this problem. Since the PC component production line adopts fully automated production, one of the important links - the placement of embedded parts, if not placed, will have a great impact on the quality of the PC components produced later, causing serious economic losses. Therefore, it is necessary to introduce the detection l...
