Rapid image processing method for double-fisheye-lens type panoramic camera

Abstract

The present invention relates to the image processing method field, and particularly relates to a rapid image processing method for a double-fisheye-lens type panoramic camera. The method comprises the following steps of S1, acquiring images in front and rear directions by two fisheye lenses and transmitting the images to a sensor, wherein the sensor is used for presenting two circular images with the view fields of the two images to be larger than or equal to 220 degrees; 2, processing the two circular images on the sensor to obtain two long strip-shaped images with the view fields of the two images to be larger than or equal to 220 degrees; 3, matching the images outside the 180-degree view fields of the two long strip-shaped images to overlap and splice the two long strip-shaped images outside the 180-degree view fields thereof; 4, cutting off the parts of the two long strip-shaped images outside the 180-degree view fields of the images to obtain a continuous panoramic image. According to the method, the splicing speed is fast and the splicing precision is high. The image presentation and the scaling in arbitrary manner can be quickly realized within the range of 360-degree view field.

Description

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. The camera uses a mechanical pan / tilt, which cannot meet the requirements of all-round camera at any moment. [0003] CN201520618862.0 discloses an external panoramic cam...

AI Technical Summary

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
