Panoramic image acquiring device

Abstract

The invention discloses a panoramic image acquiring device. The device comprises two fish eye lens modules, an image sensor and a signal transmitting line. The optical axes of the fish eye lens modules overlap with each other and the fish eye lens modules are oppositely arranged at two ends of the same optical axis; a prism is arranged at the center of a connecting line connecting the optical centers of the two fish eye lens modules. The image sensor is arranged below the prism. With the panoramic image acquiring device, complete unification of image qualities and complete synchronization of images of different fields in a panoramic image can be realized. As only one video output channel is adopted, the data collection task and panoramic splicing task in post-processing of a panoramic image can be greatly simplified, and therefore, difficulty and cost are reduced. Further, the number of image sensor chips and the number of lenses are reduced, and the cost of an image acquiring system is reduced. Images obtained from the device are higher in quality and image quality is more stable.

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...

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 th
