difference between aerial camera and surveillance camera
With the development of intelligent industry, the domestic UAV field has made a huge technological breakthrough and market coverage. UAVs have been applied to agriculture, security, national defense, entertainment and many other industries. In particular, UAV aerial photography is particularly prominent. People in the fields of multimedia, video and games all want to use UAVs to shoot a new scene of “third perspective”. A large number of professional UAV players have also emerged. So, do you know the differences between aerial cameras and surveillance cameras?
Surveillance camera
First, let’s look at the surveillance camera. As the name implies, “surveillance” is more suitable for the field of intelligent security. Generally, the definition is lower than that of professional digital cameras and higher than that of computer cameras. However, high-definition surveillance cameras have also emerged, which have been widely used in the field of urban surveillance, and there has been a major breakthrough in pixel technology.
Conventional 2 megapixel definition, 1080P ultra clear picture. The bayonet camera for road monitoring can reach up to 8 million pixels if it is 5 million pixels higher. In the special monitoring area, a maximum of 20 million pixel camera can be used. Specific scenarios are configured according to the actual cost performance ratio.
Aerial camera
High definition aerial camera, working at high altitude. It not only has high requirements on the professional level of equipment operators, but also the actual shooting conditions of the external air environment (such as wind speed, fog, dust) will have a certain impact on the imaging. This requires high response speed, image capture capability and screen resolution of the camera chip.
Due to more and more haze, fog penetration technology has been widely used in UAV camera equipment. The principle of surveillance camera imaging is that the light emitted or reflected by the target object is imaged after photoelectric conversion on the imaging device of the camera.
When the density of aerosols or solid particles in the atmosphere is large, it will form a series of blocking, scattering, refraction and other effects on the beam in the propagation path, reducing the effective light that can enter the camera, and ultimately affecting the imaging quality. Camera fog penetration technology can reduce the interference of haze on imaging through technical means, and enable the camera to obtain good monitoring effect.
The common definition of UAV is 1080P. At present, 4K UAV camera and 48 million pixel shooting have also appeared, supporting 8K video shooting UAV equipment. Whether the video or photo is taken, their picture quality is very delicate, and the details are full of vitality and vividness. And other supporting equipment can achieve the functions of information collection, biltegiratzea, analysis, transmission and so on.
