As we all know, in the process of composition, transmission, reception and processing of the picture obtained in practice, there are inevitably external troubles and internal troubles, such as the uneven sensitivity of the sensitive element of the photoelectric conversion process, the quantization noise of the digital process, the fault in the transmission process and human factors, which will make the picture change. Therefore, removing noise and restoring original picture is an important content in picture processing. The amount of data of the digital picture is appropriately large, a 512*512 pixel digital picture of the data amount of 256K bytes, if it is assumed that the transmission of 25 frames per second, the transmission channel rate is 52.4M bits/second. A high channel rate means a high cost, and it also means an increase in pervasive difficulty. Therefore, it is very important to compress the picture data in the transmission process. The data compaction of the automatic screening machine is mainly ended by the coding and conversion compaction of the picture data. Picture data coding generally uses conjecture coding, which indicates the spatial change rules and sequence change rules of picture data with a conjecture formula. 

It is assumed that after knowing the values of each adjacent pixel in front of a certain pixel, the pixel value can be guessed by the formula. By using the conjecture encoding, it is generally only necessary to transmit the starting value of the picture data and the conjecture fault, so 8 bits/pixel can be compressed to 2 bits/pixel. The automatic screening machine conversion compaction method is to divide the whole picture into small (8*8 or 16*16) data blocks, and then classify, transform and quantify these data blocks, and then constitute an adaptive conversion compaction system. This method can compress the data of a picture into a few dozen special transmissions, and then convert it back at the receiving end. The edge sharpening process is mainly to strengthen the general edges and details in the picture, to form a flawless object distance, and to achieve the purpose of separating the object from the picture or detecting the area marked with the same object surface. It is a basic problem in vision theory and algorithms in the early stage, and is also one of the important factors in the victory and defeat of vision in the middle and late stage. Automatic screening machine picture cutting is to divide the picture into several parts, each part corresponds to the surface of a certain object, when cutting, the gray level or texture of each part fits a certain uniform measure. Some of the essence is to classify pixels.

Grasp the spread of the planning industry, the survival of the fittest of the bad environment, Nasdan in the steady spread, there are many like Nasdan a selection of equipment carefully developed and produced machine scene detection and construction manufacturers in the bad market environment, the old refers to many military strength, slowly emerging good skills, give reliance on now China's national shopping mall proportion will gradually tend to be uniform, Instead of being the only one. Automatic screening machine used in the first sentence or as much as possible in front of China's e-commerce and research institutes and colleges and universities, there will be more abnormal products want to occupy a place under the Internet this big fat pork, said not to check the promotion of products from time to time and conversion of product marketing, but also to strengthen the department picture identification system research institutes and colleges and universities in the market's professional competitiveness. Is there any system that can help scientific research institutes and higher education institutions to advance quickly and reduce the damage in the short term? Most research institutes and colleges and universities will eliminate the two types of construction in the upgrade factory and high-paying recruitment of skilled personnel. And in these two preparation methods, we concluded that large research institutes and higher education institutions are increasingly aiming to eliminate the former, that is, to seek better loss reduction construction in shopping malls. Use advanced industrial camera shift eyes to perform recognition, measurement, positioning and other benefits. So what are the advantages of CCD scene detection construction? The following entry claims to recommend to the master. CCD scene detection construction is seriously for the product external short, narrow, shortcomings and so on to do the detection of picky sampling, is usually automated picky, for the factory to save a lot of labor, greatly bear the cost, deeply favored by processing factories.

The value of the optical selection machine title: for example, planning the optical selection machine only expects value, planning the time to pay for leisure, will be used will be uncomfortable for many years, when the machine meets the title, begging the manufacturer to his family to work, the manufacturer because the value sold to you is very cheap, plus for example, to his family to work, there has been no profit. The compatibility of optical selection machine software, especially for manufacturers who have not entered the optical selection machine profession for a long time, the stability of the software and the stability of the machine are often unparalleled and the long-term manufacturers in the optical selection machine profession are so strong, because the development of the optical selection machine profession is to provide long-term experience storage, and the usual long-term effectiveness of customers they will smooth the supply of customers. According to the title displayed by the user to stay and delete is a better manufacturer. Instead of being the same as the thousands of machines on the mall, just sell them in. Suzhou Nasdan Precision Technology Co., Ltd. built 16 years, constantly vivid in the painting skills and scene detection construction development and production, and work hard for the principle of customer effectiveness, the company's serious business degree for machine vision, external inspection construction, picky construction, external selection machine, detection accuracy up to 1μ, the effect of up to 30,000 pieces/hour, the rate of 99.99%. To pick out a good optical picking machine manufacturer, what the future machine title, Z less manufacturers where the effectiveness of the point of view is the ability to bear the optical picking machine, rather than encounter what standard automatic detection problem will be paid to stay and repair. Okay, take it out, and we're done.
