Industrial endoscope camera overview

Industrial endoscope camera is a precision instrument used for non-destructive testing, widely used in internal structure inspection and fault diagnosis in various industries. It uses optical imaging technology and electronic signal processing to enable operators to observe the internal surface structure or working status of the object easily and accurately without destroying the surface of the object being inspected.

Working Principle

Optical Imaging

Optical imaging is to use a lens to collect the image information inside the inspected object, and then transmit the image to an external display through a fiber optic light source. The specific steps are as follows:

1. Provide light source: provide light source illumination through a lamp tube.

2. Image acquisition: light passing through the inside of the object is imaged through a lens.

3. Image transmission: the imaged image is transmitted to an external display through an optical fiber.

Electronic Imaging

Electronic imaging is to use high-definition imaging devices such as CCD or CMOS to collect the image information inside the inspected object, and then transmit the image to an external display through a cable. The specific steps are as follows:

1. Image acquisition: The image information inside the inspected object is collected through imaging devices such as CCD or CMOS and converted into electrical signals.

2. Image transmission: The electrical signal is transmitted to an external display through a cable.

The working principle of the industrial endoscope camera combines optical technology and electronic technology, allowing operators to observe the details inside the inspected object in real time. Different industrial endoscopes may use different imaging technologies and components according to their design and application requirements.

Host image processing

The host is equipped with a high-performance processor, such as the RK3588 high-performance processor, which adopts an advanced three-level superscalar processing architecture and is equipped with ARMCortex-A76 and Cortex-A55 cores to efficiently process image data transmitted from the camera. The system supports a variety of custom color modes, and users can adjust color temperature, color difference, hue, saturation and other parameters according to different usage environments to obtain the best viewing effect.

Common types

From the perspective of the overall type of endoscope
According to the characteristics of the manufacturing process, industrial endoscopes are generally divided into three types: optical hard tube endoscopes, fiber optic endoscopes, and video endoscopes, and the corresponding cameras are also different. The camera of the optical hard tube endoscope transmits images based on optical principles; the camera of the fiber optic endoscope transmits images with the help of optical fibers; the camera of the video endoscope uses CCD (CCD solid-state imaging devices are called CCD image sensors, which are constructed by arranging many pixels on a silicon substrate, converting the imaging light on it into electrical signals, and then transmitting them in the same way to obtain image signals) instead of the image guide beam to transmit image signals, which are then processed and converted into video signals by the image processing center.

Application areas

As a high-precision optical instrument, industrial endoscope cameras are widely used in various industrial fields. The following are some of the main application areas of industrial endoscope cameras:

Automotive industry
In the automotive industry, industrial endoscope cameras are used to detect carbon deposits, wear, cracks and other problems inside the engine, helping maintenance personnel to accurately locate the fault point and improve maintenance efficiency. In addition, it can also be used to detect the status of components such as fuel systems, cooling systems, air conditioning systems and brake systems to ensure the performance and safety of the car.

Aerospace field
In the aerospace field, industrial endoscope cameras are widely used for internal inspection of key components such as aircraft engines and turbine blades. Due to the complex internal structure of aircraft and spacecraft and the high requirements for product quality and safety, the non-contact and high-precision characteristics of industrial endoscope cameras make them an indispensable inspection tool.

Petrochemical field
The petrochemical field involves a large number of equipment such as pipelines, storage tanks and pressure vessels, which may have defects such as corrosion and cracks during use. Industrial endoscope cameras can go deep into the equipment for observation and inspection, timely discover and solve potential safety problems, and ensure the normal operation of the equipment.

Power and Energy Field
In the power and energy field, industrial endoscope cameras are used in the maintenance of wind turbines to detect internal damage and corrosion of wind turbine blades to ensure the stable operation of wind turbines. In nuclear power plants, industrial endoscope cameras can be used to check the internal structure of the reactor and the condition of the fuel rods to ensure the safety and reliability of nuclear power generation.

Machinery Manufacturing Industry
The machinery manufacturing industry has extremely high requirements for product quality. Industrial endoscope cameras can be used to check internal defects such as castings and welded parts. Its high-resolution imaging and flexible controllability make every detail clearly visible, which helps to improve product quality and production efficiency.

Rail Transit
The maintenance and overhaul of rail transit equipment is also inseparable from industrial endoscope cameras. Its high imaging quality, flexible controllability, digital processing and portability make it widely used in the field of rail transit.

In summary, industrial endoscope cameras play an important role in many industries, and their application areas are still expanding. With the continuous advancement of technology, the application prospects of industrial endoscope cameras will be broader.

Conclusion
Industrial endoscope camera is an efficient inspection tool. It uses advanced optical and electronic technologies to make the inspection of internal structures simple, intuitive and accurate. Whether it is used for the maintenance of industrial equipment or the quality control of products, industrial endoscope camera plays a vital role.
