Technical Background
Before deep learning algorithms came out, for vision algorithms, it can be roughly divided into the following 5 steps: feature perception, image preprocessing, feature extraction, feature screening, and inference prediction and recognition.
In the early days of machine learning, features were of little concern in the dominant statistical machine learning community. Deep learning is an aspect of machine learning techniques supported by artificial neural networks. Deep learning techniques work by teaching machines to learn by example. By providing the neural network with labeled examples of specific types of data, common patterns between these examples can be extracted and then converted into mathematical equations. This helps in categorizing future information. With visual detection techniques, the integration of deep learning algorithms can differentiate between parts, anomalies, and characters, simulating human visual detection while running a computerized system.
So what exactly does this mean? Take an example. To create visual inspection software for automotive manufacturing, you should develop a deep learning-based algorithm and train it using examples of defects that must be detected. With enough data, the neural network will eventually detect defects without any additional instructions. Deep learning-based visual inspection systems excel at detecting defects that are complex in nature. They can not only address complex surfaces and cosmetic defects, but also generalize and conceptualize the surfaces of complex parts.
In recent years, as the competition between China and the United States in the field of science and technology is becoming more and more intense, the "new quality productivity" with independent intellectual property rights is getting more and more attention, and new breakthroughs have been ushered in the field of industrial-grade measurement technology, and a kind of a priori pure visual perception technology has been innovatively applied in the field of catheterization measurement, which is a kind of perception and understanding technology based on pure visual information. This technology is a pure visual information based on perception and understanding of the technology. It does not rely on any a priori knowledge or a priori model, but only through the analysis and processing of the input image to obtain an understanding of the image content. AMB Tube-Q catheter digital measurement system can cope with complex catheter measurement scenarios, to meet the requirements of catheter manufacturing enterprises for high-precision measurement (0.01mm), high-efficiency inspection, product inspection, shaped tube inspection, non-contact inspection, data traceability, digital management and so on. management, digitalization, etc.
Catheter is an important part of complex electromechanical products in modern aviation, aerospace, automotive and other industries, widely used in the industrial field, known as "industrial blood vessels", especially in the aviation engine is more significant. Engine on the dense piping is mainly divided into fuel pipe, lubricating oil piping, actuator or control valve piping, gas pipe, ignition and sensor cable, responsible for fuel, coolant, gas, control signals, etc. to the designated parts or control valves, and its reliability is directly related to the performance of the whole machine and life. Ensure that the three-dimensional dimensions of the elbow space, interface dimensions and sealing surface accuracy is very critical, fast and accurate measurement of the elbow is to ensure its precise assembly, stress-free installation and effective sealing of the core technology.
However, due to the catheter in order to match the high integration of the assembly, the form is usually the shape of different diameters, complex body shape, curvature of a variety of, so that to the pipeline measurement has brought a huge challenge, and nowadays the products are in the direction of high integration of precision manufacturing, the parts of the higher and higher precision requirements, the traditional measurement technology has become more and more difficult to meet the needs of modern production.
In the field of catheter production, the main limitations of conventional measurement techniques are as follows:
1, quality inspection results qualitative, low tooling flexibility;
Traditional conduit size inspection relies on various types of measuring calipers, gauges, due to the conduit often exists in different bending directions, bending arcs at the point of inaccuracy, resulting in quality inspection personnel can not accurately measure the bending pipe in all directions of the linear dimensions, the bending angle, the bending radius, the first and last interface positional tolerances and other key dimensions and accuracy, measurement of time-consuming and laborious.
Measurement using the gage requires parts specifications and gage one-to-one correspondence, manual release, manual measurement, can be measured by the gage decision, in order to match the different specifications of the product, the need to customize the development of a variety of gages, the cost is not expensive, while the need for regular maintenance, occupies a large amount of space for storage, a lot of factories gage stacked up, the regular gage no specific test data output, only through the shape of the catheter and the gage to do a qualitative judgment of the match, no specific deviation quantitative parameters, no specific deviation quantitative parameters. No specific deviation quantitative parameters, while the detection of generality, poor flexibility.
2, serial production, assembly and matching low efficiency;
In the traditional industrial production of aircraft development system, due to the catheter without digital measurement, pre-assembly quality inspection link can not be accurately informed of the parts tolerance size, can only rely on the adaptive serial assembly, and then expose the catheter of various types of size and accuracy and other issues, need to be repeatedly adapted, i.e., the production of the catheter serial in the engine assembly process, the catheter is also a serial relationship, resulting in the catheter production cycle is long, and has become a limitation of engine This has led to a long production cycle for the catheters, which has become a bottleneck limiting the engine's production capacity.
State of the art and limitations of modern 3D vision measurement techniques:
1, the current state of the art;
The four mainstream 3D vision measurement technologies in the current market are binocular imaging, 3D structured light, TOF time-of-flight method, and laser triangulation. binocular vision is based on the principle of human binocular recognition, the system structure is simple, but the amount of computation is large, the calculation is complex, and the accuracy of the measurement is poor for the scene of dark light or overexposure. the TOF time-of-flight method has the advantages of correspondingly fast, simple software, and long recognition distance, but the Low resolution, poor imaging, and high hardware cost.3D structured light measurement is simple in calculation, high in accuracy, and can measure for low light environment, objects without obvious texture and shape change, also subject to structured light hardware investment and high cost. Laser triangulation method has high accuracy in short-distance measurement, and the accuracy decreases as the measurement distance increases.
2, limitations;
The market mainstream vision measurement products have their own strengths and weaknesses, subject to various foreign core supporting hardware and software price limitations, the whole set of vision system cost is high, a set of 3D vision measurement system price of up to millions of dollars, for the general entity of the manufacturing industry price is not friendly. Therefore, the integration of 3D vision measurement technology and algorithms, reduce hardware configuration and software localization, independent and controllable is the key to help intelligent manufacturing and digital production.
