Problems solved by technology

[0002] At present, the development of 3D reconstruction and panoramic viewing video surveillance is in full swing. The entire imaging system often uses multiple lenses for imaging, and then image synthesis and splicing can be realized. The negative impact of this is the increase in lens costs; harsh environments such as high and low temperature also affect Imaging System Performance and Stability

Abstract

The invention discloses a high-definition panoramic looking-around optical imaging system. The high-definition panoramic looking-around optical imaging system is provided with a front lens set, a diaphragm, a rear lens set, an optical filter and protective glass in sequence from an object plane to an image plane, wherein the focal power of the front lens set is negative; the front lens set comprises a first lens, a second lens and a third lens; the focal power of the first lens and the second lens is negative and the focal power of the third lens is positive; the focal power of the rear lens set is positive; the rear lens set comprises a fourth lens, a fifth lens and a sixth lens; and the focal power of the fourth lens and the sixth lens is positive and the focal power of the fifth lens is negative. By adopting the high-definition panoramic looking-around optical imaging system disclosed by the invention, a high-definition camera lens with an ultra wide angle, a large relative pore diameter and mega pixels and with the maximum view field angle of 230 degrees can be used in the aspects of three-dimensional reconstruction, panoramic browsing video monitoring, dome-screen projection and the like; and the imaging system still has relatively high definition in a temperature range from -40 DEG C to +85 DEG C and is especially applicable to a bad vehicle-mounted environment.

Description

【Technical field】 [0001] The invention relates to an optical system, in particular to a high-definition panoramic surround-view optical imaging system. 【Background technique】 [0002] At present, the development of 3D reconstruction and panoramic viewing video surveillance is in full swing.
