One of them, electronic endoscopy is a kind of endoscope that puts a miniature image sensor (CCD, Charge Couple Device or CMOS, Complementary Metal Oxide Semiconductor) into the tip of the endoscope, and transmits image signals by cable. The electronic endoscope converts light energy into electrical energy through the miniature image sensor, and then goes through the video processing center, processes the image, and then stores and reconstructs it through various methods, and at the same time displays it on the display screen, which improves the quality of the image to a large extent, overcomes the shortcomings of the optical fiber that is easy to break and has a short life span in the process of using it, and does not have the disadvantage of the black spot that occurs in fiber endoscopes due to fiber breakage. Disadvantages.
Electronic endoscopic image processing technology enables doctors to easily obtain information about the lesions in the observation area, and even extract information about the lesions and potential lesions that cannot be observed with the naked eye, thus improving people's diagnosis of clinical diseases. If combined with other medical tools, tissue slices of suspected lesions can be extracted from the human body and various minimally invasive surgeries can be performed, which will bring the diagnosis and treatment of clinical diseases and the discovery of early lesions into a new stage of development. Easier identification of potential lesions in medical diagnosis is the future development direction of endoscopy. In terms of image processing and information extraction, the latest technologies currently used include: magnification endoscope, Narrowband spectral imaging technology (NBI), Autologous fluorescence imaging (AF), and AF. fluorescence imaging (AFI), Near infrared imaging (IRI), Multi-functional imaging technology, etc.
Technical points: Specifically from the point of view of the latest technologies studied at home and abroad, mainly focusing on image acquisition, image processing and information extraction, illumination mode of hardware and software research. (l) image acquisition system, generally including imaging lenses, micro image sensors, acquisition and processing circuits and other components; (2) in order to detect lesion characteristics, image processing and information extraction; (3) lighting is also one of the key technologies of the electronic endoscopy, whether the color reproduction of the lighting is good or not is directly related to the performance of the whole endoscope.
Advantages of endoscope:
Endoscope technology has a unique advantage, it can extend people's sight distance, and can arbitrarily change the direction of sight, and accurately observe the real condition of the inner surface of the object, which can not be replaced by other testing instruments. Advantages of endoscope are as follows: (1) clear image, color fidelity, high resolution, endoscope image after special processing, the image will be enlarged, the observation of small matters is particularly suitable.
(2) has the function of video recording and photo taking? Can store the picture, easy to view and continuous control observation, reduce endoscopy time.
(3) Avoiding the shortcomings of the optical fiber being easy to break, the brightness of the light guide being easy to decay, and the image magnification being easy to be distorted.
(4) The camera is made of scratch-resistant and grease-resistant glass shell, precision mold injection molding, and some parts are made of stainless steel casting molding, which ensures that the product is durable, waterproof, abrasion-resistant and corrosion-resistant, and improves the durability in the harsh environment.
(5) equipped with external rechargeable battery, portable high-definition color LCD monitor, greatly facilitating the use of outdoor long time, and can be equipped with a dedicated video capture card for real-time capture, a key can be achieved. Can be connected with a monitor or display, real-time high-definition display of detection images. Realize 1 person operation, more people can watch at the same time. Convenient for diagnosis, consultation and teaching.
(6) From the remote probe to the hand-held handle, industrial electronic endoscopes have strong water resistance and excellent resistance to mineral and synthetic lubricants, aviation fuel, kerosene, gasoline and diesel.
(7) Borescope is cost-effective and value for money, this model has great competitiveness in the market both in terms of price and performance, and it is your first choice for pipeline video inspection, precision instrumentation inspection and so on.
