360-degree high-definition surround view panoramic lens

Abstract

The invention discloses a 360-degree high-definition surround view panoramic lens and belongs to the field of optical lenses. The 360-degree high-definition surround view panoramic lens is realized by adopting a small number of lenses and arranging the lenses in a certain way, and in this way, production cost is reduced. The lens is composed of a reflector, a lens assembly with positive focal power, and an optical filter, wherein the reflector is a non-spherical reflector, and the lens assembly with positive focal power comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens. The lens is lower in production cost, simple in structure, low in manufacturing cost, and capable of achieving the resolution ratio of 1080P and 720P high-definition detector. The pick-up lens has a unique property of 360-degree observation, all personnel and activities can be seen, target determination speed is increased, emergencies can not be missed, and panoramic monitoring is realized in the true sense.

Description

technical field [0001] The invention belongs to the field of optical lenses. Background technique [0002] Modern imaging devices have been widely used in various fields. In order to meet people's increasing demand for capturing video information, when imaging devices are used in certain specific fields, such as network video conferencing, commercial monitoring, forestry monitoring, etc., it will be necessary Full-time 360-degree panoramic surveillance. Panoramic photography needs to achieve no blind spots and no dead angles in the panoramic range, and can look at the whole situation without using complicated "expansion software" or stitching multiple images. At the same time, the development of imaging detector technology has greatly improved the resolution and number of pixels of the detector. Nowadays, high-pixel cameras such as 1.3 million pixels (720P), 2 million pixels (1080P), and 3 million pixels are the mainstream. The imaging quality of the lens, the size of the...

Problems solved by technology

However, the characteristics of the transmission fisheye lens determine that as the field of view increases from -55 degrees to +20 degrees, the lens will produce serious negative distortion, which makes the image information of the peripheral field of view severely compressed, which greatly limits the peripheral field of view. clarity

At the same time, the size of the traditional transmissive panoramic lens cannot meet the requirements of lightness, thinness and shortness, and the production cost of a single lens is relatively high
