What is machine vision_What is the major of machine vision

Machine vision is a technology and field that uses computers and virtual reality technology to obtain and process image information through cameras, image sensors and other devices. It mainly researches and develops algorithms and methods that enable machines to perceive and understand visual information such as images and videos.

Machine vision is a technology and field that uses computers and special hardware equipment to imitate human vision systems. It aims to enable computers to acquire, process and understand image or video data to perform various tasks, just like humans use their eyes and brains to process visual information.

Machine vision or computer vision uses robots to replace the human eye for measurement and judgment, which is an important aspect of pattern recognition research.

Machine vision and control engineering are two different majors, but they have some similarities. Machine vision is a discipline that studies how to make computers "see", which involves image processing, pattern recognition, artificial intelligence, etc.

I. Basic principle of machine vision system

1. Principle of machine vision system: Machine vision system refers to the use of computers to realize human visual functions, that is, to use computers to realize the identification of the objective three-dimensional world. According to the current understanding, the sensory part of the human visual system is the retina, which is a three-dimensional sampling system.

2. Generally speaking, the working principle of machine vision equipment is to make robot vision hardware mainly include images.There are two parts of acquisition and visual processing, and image acquisition consists of lighting system, vision sensor, analog-digital converter and frame memory, etc.

3. CCD machine vision system, also known as CCD vision system, is an image processing system based on charge-coupled devices (CCD). It uses CCD cameras to capture images and process and analyze them through specialized image processing algorithms and software. This kind of system usually includes the hardware part and the software part.

4. Components of the machine vision system Light source: The light source is the basic condition for acquiring images. Its function is to illuminate the object to be detected and highlight the contrast between the measured part of the object and the background, so as to form an imaging effect to facilitate the processing of the image processing unit.

5. CCD visual detection equipment uses machines instead of human eyes for measurement and judgment.

Function of pathological image analysis system

1. The launch of pathological graphic and text analysis system has greatly reduced the operator The workload of the staff. The observation mode under the high-resolution display almost completely replaces the dizzying under-mirror observation mode. The staff's cervical spine and eyes are not easy to get tired. At the same time, greatly improve work efficiency and improve the overall level.

2, 2-flow cytometry: It can determine the intracellular DNA content and multiplier, cell cycle and cell immune type. 3 Image analysis technology: It can quantitatively determine the lesion organs, tissues and cells.

3. Cell tracking: Through image analysis software based on tracking cell movement, morphological changes, physiological functions, etc., cells can be identified, analyzed and tracked from a large number of multi-dimensional data of on-site imaging, and various forms of visual images and data can be generated.

4. Due to financial problems and the level of instrument design, most medical image equipment does not consider the storage and transmission functions of images, and at best configure a printer or X-ray film for image recording. The doctor's diagnosis is through naked eye observation of the image of the instrument screen, and the analysis and diagnosis based on personal experience, which has more subjective components.

What's wrong with the automatic image adjustment of win7 system?

1. Question 4: In win7 system, the monitor always pops up the image and adjusts automatically. How to turn it off? 10 points. There are two possibilities. One is that there is a problem with the button on your display. Pressing it in but it does not come out. You can deduct him.

2. That may be a problem with the monitor. Take it to check it. Automatic adjustment of computer monitor image solution 3: There is a problem with the general monitor button, such as too much dust, poor contact, etc., you can remove the dust.

3. The automatic adjustment button of the monitor is damaged, so it is constantly adjusted automatically. This button should be checked carefully and replaced if necessary.There is a problem with the main control panel of the indicator, which needs to be repaired. If there is an error in the graphics card or monitor driver, you can reinstall the graphics card or monitor driver.

4. If the resolution is set improperly, just set the output resolution to the resolution of the display.

What is the basic composition of the computer image processing system

The basic composition should consist of the following parts: capture card, used to obtain image data Image preprocessing part, used for pixel statistics and histograms Statistics, etc. The image processing part is used to analyze the image. The image post-processing part is used to use the results of image analysis for special purposes or special applications.

The software part is input by data,Program composition of image transformation, image recovery and enhancement, image classification, statistical analysis and editing output. There are three types of system service objects dedicated to scientific research, product production and both.

Computer is a digital processing device, so classical computer image processing mainly refers to digital image processing, which includes spatial domain processing, frequency domain processing, restoration processing, compression processing, Morphological processing, segmentation processing, etc.

The hardware system is the "torso" of the computer and the material foundation. And the software system is the "soul" built on this "torso". Computer hardware The computer hardware system consists of five major parts: operator, controller, memory, input device and output device.

Introduction to the core image acquisition system (excerpt)

The core image acquisition work mainly includes selecting the scanning type, adjusting the scanning box, determining the scanning parameters, core decoration, image acquisition and image storage. 1) Select the scanning type according to the characteristics of the rock core. In the absence of special requirements, white light flat motion scanning is carried out; only rolling scanning is carried out on the special lithology segment that has completed the whole rock core.

Abstract This article systematically introduces the core image scanning analysis technology, and explains the calculation method of image processing and related sedimentary tectonic parameters. Taking the Chegu 201 well as an example, through the combination of core observation and core scanning analysis, the reservoir space development of the Paleozoic Ordovician carbonate reservoir of the well The characteristics and oil content have been comprehensively analyzed.

The core image acquisition system applies linear array CCD NEC μPD8872. The control heart piece of CCD adopts LM9833, 48-bit color, 1200dpi USB image scanning heart piece. The linear array CCD digital image acquisition system finally transmits the processed image information to the PC through the USB0 protocol interface chip using a USB data cable.

The current dedicated core scanner has a resolution of up to 1200DPI, up to more than 47,000 pixels per meter. Image acquisition of the outer surface of the core. There are generally two collection methods: fluorescent scanning and white light scanning. White light can be scrolled 360-degree.
