Optical haze transmission refers to the principle that visible light cannot penetrate through clouds and smoke, but near-infrared radiation can penetrate through certain concentrations of fog and smoke. Optical haze transmission utilizes the principle that near-infrared radiation can diffract tiny particles to achieve accurate and fast focusing. The key technology is mainly in the lens and filter. By using the principle of optical imaging through physical means, the image clarity is improved.

Infrared thermal imaging camera algorithm fog penetration technology

Infrared thermal imaging camera algorithm fog penetration technology, also known as video image enhancement technology, generally refers to making images that are unclear due to fog, water vapor, dust, etc., clear and emphasize certain interesting features in the image, suppress uninteresting features, and improve image quality and enhance information.

Infrared thermal imaging camera electro-optical fog penetration technology

Professional thermal imaging camera electro-optical fog penetration technology combines the above two functions, and realizes color image output through integrated operation of the embedded FPGA chip and ISP/DSP. On the one hand, this fog penetration technology of the IR thermography camera can distinguish distant scenery, close-up scenery, and fog density and other factors, select the penetration level, and achieve the best regional effect, which is different from the overall improvement of image contrast in the past, with no delay. On the other hand, the high-speed operation of the chip will inevitably produce noise points, which will have a particularly significant impact when the night light is insufficient. Therefore, the integrated machine chip generally needs to use a CCD sensor and a large aperture lens to achieve good low-light effect. It is currently the best fog penetration technology on the market.

Infrared thermal imaging camera false fog penetration technology

This is mainly achieved by manually adjusting the contrast, sharpness, saturation, brightness and other values, or making some filter switching devices, so that the key points of the image are highlighted, thereby improving the subjective visual effect. The disadvantage is that it cannot refocus on the scenery, which is difficult to satisfy visual experience.

The defogging technology present in infrared thermal imaging cameras is capable of improving video surveillance quality from various angles, particularly under foggy weather conditions. This technology enhances image contrast, transparency, and clarity, resulting in a significant improvement in the amount of detail captured. Thermal lenses effectively bring to light previously hidden image details. Moreover, defogging processing can enhance image saturation, making colors vivid and natural, while retaining accuracy and tone. This yields a visual experience that guarantees good image quality.

Professional thermal imaging camera can display the temperature field of objects, which transforms the surface temperature distribution of targets that cannot be directly seen by human eyes into thermal images that can be recognized by human eyes. While obtaining the thermal image of the object, the non-contact infrared energy detected by the thermal imaging system is quantified and calculated by intelligent temperature measurement algorithm, which can accurately measure the surface temperature value of the object being photographed. It can be used in temperature warning monitoring scenarios to prevent fires caused by temperature changes, such as in electric power, petrochemicals, forest fires, and other fields.
