Drones are advanced aerial assets, and their superior aerial imaging has created huge benefits for many industries. Night vision drones are a special kind of drone that bring great advantages to emergency search and rescue (SAR) operations at night.
What is night vision technology?
The drone camera is similar to the human naked eye imaging principle. Human vision is limited to a small part of the electromagnetic spectrum, known as visible light. The rest of the spectrum—radio, infrared, ultraviolet, X-rays, gamma rays—is imperceptible to the naked eye. On the other hand, if the camera is equipped with the right sensor, it can pick up different wavelengths of light.
Light wavelength night vision refers to vision in dark and weak light environments. Different technologies enable night vision, the most common being thermal imaging and starlight/twilight sensors.
Can drones shoot at night?
Most drones are allowed to fly at night and are also allowed to film at night. The image quality of night scenes taken by drones depends on the camera sensor. The aperture and CMOS size of the drone using the RGB camera sensor determine the amount of incoming light, which directly reflects the sensitivity of the drone image.
The image taken by the drone using the thermal imager depends on the level of ambient heat, and the thermal difference provides a guarantee for the night vision of the thermal imaging drone. But at the same time, the thermal imager will also be disturbed by surrounding factors, which will cause some areas to be invisible, and the temperature measurement accuracy will be inaccurate.
The image taken by the drone with the starlight/twilight sensor adopts digital image enhancement technology, which combines the characteristics of RGB image + infrared image, and only needs a small amount of light source to achieve clear black and white images at night and in low light environments.
Does Autel have a night vision drone?
Autel drones, whether they are consumer drones or enterprise drones, have pretty good image sensors for aerial photography.
Best Night Vision Drone: Autel EVO MAX 4N
The "N" of the EVO MAX 4N drone stands for Night Vision Camera, also known as Starlight Camera. EVO MAX 4N has a maximum photo pixel of 2.3MP and an ISO of 450,000. Meanwhile, the EVO MAX 4N drone camera gimbal also includes a wide-angle camera, a thermal imaging camera and a laser rangefinder.
