Application and development prospect of photoelectric pod

Photoelectric pod is an important part of photoelectric detection and alarm technology and its equipment, widely used in land, air, sea and other fields, carried in aircraft, ships and other loads for reconnaissance, power inspection, environmental monitoring, disaster prevention and mitigation, police investigation certificates. Especially with the vigorous development of UAV technology in recent years, higher requirements are put forward for the miniaturization, miniaturization, multi-spectrum, lightweight and other performance convenience of photoelectric pods.

In recent years, the demand for photoelectric pods in the civilian field has grown rapidly, especially with the outbreak of the drone market, the demand for photoelectric pods in this field has increased rapidly. In addition to the drone industry, photoelectric pods can also be used in public security monitoring, dangerous rescue, meteorology and agriculture. Fire protection can use photoelectric pods for forest fire prevention, and through imaging the forest temperature distribution, timely detection and prevention and control of areas prone to fire can be detected; In agriculture, you can use pod photography to detect the temperature of crops and understand the effect of irrigation; In the environmental protection industry, photoelectric pods can visually monitor sewage and gas emissions; In the emergency field, the photoelectric pod can clearly obtain first-hand temperature information on the spot, and is not affected by smoke and brightness. China has a vast territory, a large population, national construction and development is in a period of rapid development, market demand has maintained steady growth, and it is expected that the future photoelectric pod market scale will reach 200 billion yuan.

Tellhow infrared photoelectric pod

The P series photoelectric pods developed and produced by Tellhow Infrared are divided into two specifications: miniaturized pods and high-precision pods. It has the characteristics of high stability and precision, long distance and high integration, and can realize all-weather search, identification, tracking and other functions.

The miniaturized pod is equipped with high-resolution visible light camera, uncooled infrared thermal imager, human eye safety laser rangefinder, etc., and the stability accuracy can reach 80urad. The size of the pod is only Φ180×260mm, and the weight is less than 3.5kg, which is conducive to the long endurance of the carrying platform. The high-precision pod is equipped with high-resolution visible light camera, refrigerated infrared thermal imager, laser camera, precision positioning module, etc., and the stable accuracy can reach 20urad.

At the same time, it has superior visual axis stability performance and automatic target recognition and tracking ability, which ensures that due to the inevitable rolling, vibration and other objective adverse conditions on the sports carrier, all kinds of photoelectric imaging detectors have clear imaging and excellent image quality; At the same time, the effective targets in the target scene image are automatically identified and stably tracked, and the recognition detection probability is high and the tracking is stable.
