Problems solved by technology

The advantage of this device is that it can take pictures in the form of a virtual pan-tilt, but its disadvantages cannot be ignored. When the two fisheye lenses are combined and edited, the accuracy is poor.
[0004] The fisheye lens of the traditional panoramic camera device has a small field of view angle, low installation accuracy, and uses two internal reflection light reflection components. The picture collected by the optical sensor is greatly deformed. When processing the image collected by the optical sensor , due to the problem of picture precision, its processing is difficult

Abstract

The invention relates to the field of photographic equipment, and in particular to a photographic device including a sensor, a light reflective element and two fisheye lenses. The sensor is connected to an image signal processor. Each fisheye lens has a field of view greater than or equal to 220 degrees. The light reflective element is provided with two outer reflective surfaces thereon respectively matched with the fisheye lenses. An included angle between each fisheye lens and the corresponding outer reflective surface is 45 degrees. An included angle between the sensor and each outer reflective surface is 45 degrees. The axial deviation of the two fisheye lenses is less than 2 filaments. The photographic device solves the problems of poor picture realistic performance and bad picture splicing effect of a traditional panoramic photographic device, and effectively improves the picture realistic performance and the picture splicing precision.

Description

technical field [0001] The invention relates to the field of imaging equipment, in particular to an imaging device. Background technique [0002] CN201521074630.X discloses a panoramic camera, which includes a base, a main control chip, a WIFI module, a wired interface, a 360 ° rotating disc, a 180 ° rotating rod, a camera, a dome cover and an alarm, and the base passes through a 360 ° rotating disc, 360 ° There is a ball cover on the outside of the rotating disk, a rotating rod on the 360° rotating disk, a camera at the end of the rotating rod, and a main control chip in the base, which is connected with the WIFI module and the camera. There are wired interface, power interface, audio interface, microphone interface and SD card slot.
