What are the advantages of vision system compared with traditional machine vision?

所属分类:


【概要描述】The original resolution of traditional machine vision is not high. In addition, it is also affected by video damage, such as repeated A/D conversion, electromagnetic transmission interference, interlaced scanning, and D1 image synthesis and de-interlacing. When it actually reaches the human eye, it is very blurred. However, in practical applications, the definition does not reach the theoretical value level. The vision system uses digital signal transmission to convert optical signals into digital signals, and then carries out image compression and processing through DSP. Then, the digital compressed video is output through the network. The ordinary vision machine has the ability of anti-electromagnetic interference and progressive scanning, and the image resolution has unparalleled advantages. The vertical resolution of the traditional vision system is 625 lines under the PAL system, 575 lines after blanking, the maximum current limit is 540 lines, and the minimum can reach more than 800 lines. From the above perspective, the maximum resolution of the traditional vision machine can reach D1 or 4CIF, about (400000 pixels), while the vision system has no such limit, and can reach millions of pixels or even tens of millions of pixels, The performance of pixels and sharpness between the two is completely different. The vision system uses the progressive scanning mode to scan each frame of the image through the electron beam. The traditional scanning mode of the vision system uses the interlaced scanning. The interlaced scanning frequency is half of the progressive scanning frequency. Due to the working principle of the interlaced scanning, there are many disadvantages in its application, such as inter-line flicker, parallelism or the zigzag shape of the vertical edge, and other adverse effects, And the overall motion image definition is reduced. The color of vision software may be more realistic than vision. The brightness signal and chrominance signal in the video signal occupy the same frequency band. When the video capture chip is used for comb filtering (bright color separation), it is difficult to completely separate the chrominance and brightness signal, which leads to the color penetration of speckle and image. Machine vision can eliminate the hidden danger because the color is more realistic, more layered, and the image saturation is better. Machine vision needs to wire and match the control line, video line, audio line and power line in an independent form. Wiring is very troublesome and complex, with a large workload, and the cost of integrated wiring is high. There are many limitations in engineering applications.

Comparison between optical fiber sensor and traditional sensor

At present, in the Chinese market, fiber Bragg grating (equipped with ASE broadband light source) and distributed sensor based on optical time-domain reflection are the most widely used optical fiber sensing technologies. This technology can basically meet the needs of the medium and low end general market and is well known by industry insiders. The single-frequency fiber laser with spectral linewidth as narrow as 2 kHz and the latest generation of optical sensing technology introduced now are completely different from the optical fiber sensing we now know. This new technical solution can fully meet the higher demand for ultra-long distance, ultra-high precision and ultra-high sensitivity in the high-end market, which cannot be completed by electric sensing and general optical fiber sensing. However, this technology is still in the stage of project approval and pre-research in China. Compared with traditional sensing technology, fiber-based sensors have the following major advantages: 1. Light weight, compact structure, easy to reuse in multiple ways; 2. Resistance to harsh environment, electromagnetic interference and chemical corrosion; 3. There is no need for electricity at the sensing point, and long-distance distributed sensing is possible; 4. Low cost mass production After optical fiber communication, optical fiber sensing has also ushered in an important development opportunity. It has extensive and huge application value in security, military, oil/gas, electricity and scientific research, especially in western developed countries. The optical principle of single-frequency fiber laser for optical sensing is optical frequency time-domain reflection.

Structure principle and classification of optical fiber sensor

1. Structure principle of optical fiber sensor The traditional sensor based on electricity is a device that converts the measured state into measurable electrical signals. Its power supply, sensitive components, signal receiving and processing system and information transmission are all connected with metal wires. Optical fiber sensor is a device that converts the measured state into a measurable optical signal. It is composed of optical transmitter, sensing element (optical fiber or non-optical fiber), optical receiver, signal processing system and optical fiber. The light emitted by the optical transmitter is guided to the sensitive element through the source optical fiber. At this time, a certain property of the light is modulated by the measured, and the modulated light is coupled to the optical receiver through the receiving fiber, so that the optical signal is converted into an electrical signal, and finally the desired measured signal is obtained through signal processing. It can be seen that the optical fiber sensor is essentially different from the traditional sensor based on electricity in measuring principle. Traditional sensors are based on mechanical-electrical measurement, while optical fiber sensors are based on optical measurement. Light is a kind of electromagnetic wave, whose wavelength ranges from 1 mm in the far infrared to 10 nm in the far ultraviolet. Its physical and biochemical effects are mainly caused by the electric field. Therefore, when discussing the sensitive measurement of light, we must consider the vibration of the electric vector E of light, namely A - amplitude vector of electric field E; ω—— Vibration frequency of light wave; φ—— Optical phase; T - propagation time of light. It can be seen that as long as one of the parameters such as the intensity, polarization state (direction of vector A), frequency and phase of the light changes with the change of the measured state, or is modulated by the measured state, then the required measured information can be obtained by adjusting the intensity modulation, polarization modulation, frequency modulation or phase modulation of the light. 2. Classification of optical fiber sensors Note: MM multimode; SM single mode; PM polarization maintenance; a. B, c functional type, non-functional type, pickup type
