Panoramic image acquisition device

Abstract

The invention discloses a panoramic image acquisition device. Including the fisheye lens module, image sensor and signal transmission line, there are two groups of fisheye lens modules, the optical axes of which overlap each other, and are relatively arranged at both ends of the same optical axis. A prism is provided, and below the prism is an image sensor that simultaneously collects images of two fisheye lens modules. The panorama image acquisition device of the present invention realizes the complete unification of the image quality of different fields of view in the panorama image and the complete synchronization of the pictures; at the same time, the panorama image acquisition device has only one video output, which greatly simplifies the data acquisition task of later panoramic image processing And panorama stitching tasks, reducing the difficulty and cost; reducing the number of image sensor chips and lenses, reducing the cost of the image acquisition system, higher imaging quality, and more stable image quality.

Description

technical field [0001] The invention relates to a panoramic image acquisition technology, in particular to a technology for realizing the acquisition and processing of a full-heaven spherical panoramic image. Background technique [0002] At present, the widely used panoramic image acquisition device is obtained by collecting the images in different angles of view separately by multi-channel sensors. At least two image sensors are required. The mainstream uses two-channel, three-channel, four-channel, five-channel, Six-way or even more to get panoramic images. The field of view of the multi-channel lens covers a field of view greater than 360 degrees. Although panoramic images can also be collected, since multiple different sensors are used to independently collect images in different fields of view, the sensitivity parameters of multiple sensor chips are different. There will be differences in imaging effects such as color temperature, brightness and darkness in images col...

Problems solved by technology

The field of view of the multi-channel lens covers a field of view greater than 360 degrees. Although panoramic images can also be collected, since multiple different sensors are used to independently collect images in different fields of view, the sensitivity parameters of multiple sensor chips are different. There will be differences in imaging effects such as color temperature, brightness and darkness in images collected by different sensors. In addition, since the image signals collected by multiple sensor chips cannot be synchronized well, it will also cause the same moving object to be displayed in different places. The posture and position in the imaging of the sensor appear out of sync

[0003] At the same time, multi-sensor applications have high requirements for back-end image processing chips, not only requiring at least two channels of video input and screen synchronization, but also high requirements for hardware interfaces, drivers, computing power and other indicators. Currently, such processing chips on the market The cost of the device is generally relatively high, and the development difficulty and cost are also relatively high, and it is difficult to cooperate with the existing image processing module; at the same time, the module requires multiple sensors and lenses, which increases the cost of additional modules
