Embodiment Construction

[0037] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments of the description:

[0038] Such as Figure 1-3 As shown, a kind of large target surface low-illuminance all-sky camera system provided by the present invention includes a sensor chip 1, a right-angle prism 2 and two wide-angle lenses 3, and the right-angle prism 2 is provided with two mutually perpendicular reflections Surface 21, the two wide-angle lenses 3 are symmetrically arranged on both sides of the rectangular prism 2 and the incident optical axis of each wide-angle lens 3 forms an included angle of 45 degrees with the reflection surface 21 on the corresponding side. The incident light rays deflected by the two reflective surfaces 21 form an included angle of 45 degrees with the two reflective surfaces 21, the field angle of the wide-angle lens 3 is more than 220 degrees and the distortion F-θ<15%, the wide-angle lens Th...

Abstract

The invention discloses a large target surface low illumination level all-celestial shooting system, comprising a sensing chip, a rectangular prism and two wide-angle lenses. The rectangular prism is provided with two reflection surfaces; the two wide-angle lenses are symmetrically arranged on two sides of the rectangular prism and a 45-degree included angle is formed between the incident light axis of each wide-angle lens and the reflection surface of the corresponding side; the 45-degree included angles are formed between the sensing chip and the two reflection surfaces; the visual field angle of the wide angle lens is more than 220 degrees and F-Theta distortion is smaller than 15%; the effective rear intercept of the wide angle lens is greater than 5.6mm; the system utilizes two wide angle lenses with visual field angles greater than 220 degree to converge the light rays which are then imaged on the same sensor chip after refraction by the rectangular prism; two wide angle lens commonly use one sensor chip to constitute a large target low illumination level all-celestial shooting system, which increases the effective aperture of the system, reduces the distortion of the edge of the system, greatly improves the resolution ratio of the integral system and enables the system effect to achieve the all dimension 720 degree visual effect.

Description

technical field [0001] The invention relates to a low-illuminance all-sky camera system with a large target surface, which is suitable for DV, sports, stage shooting, hotels and the like. Background technique [0002] With the continuous development of my country's social economy, people's living standards are improving day by day, and people's requirements for quality of life are getting higher and higher. People are becoming more and more keen on participating in tourism, performances, sports and so on. In order to remember the good memories of the past, people use cameras, DV and other tools to record the exciting moments. However, most of the existing cameras and DVs currently on the market can only record pictures at a certain angle ahead, and cannot record all the scenes of the beautiful pictures at that time, or because the price of the existing panoramic cameras on the market is too high, the quality of the captured images is not good enough. Not so good. And make...
