Abstract

The invention provides a panoramic video image stabilization method based on an inertial measurement unit. The method comprises the steps of S1, calibrating the inertial measurement unit and a panoramic photographing device main lens; S2: synchronizing the time stamp of the inertial measurement unit with the time stamp of a panoramic video frame; S3: acquiring the rotation matrix R' of a current frame in real time by using the inertial measurement unit; S4: acquiring the rotation matrix M of the current frame of video; and S5: rotating a panoramic image according to a current rotation matrix to generate a stable video frame. The present invention also provides a panoramic video image stabilization system for the panoramic video image stabilization method based on the inertial measurement unit. The system comprises a panoramic photographing module, an inertial measurement unit, a calibration module, a synchronization module, a calculation module, and a processing module. The method solves the problem that the image of the panoramic photographing device is unstable in the driving process of a carrier such as a vehicle or the like when the panoramic photographing device is placed on the carrier such as the vehicle or the like, and improves user experience.

Description

technical field [0001] The invention relates to the field of panoramic video processing, in particular to a method and system for panoramic video image stabilization based on an inertial measurement unit. Background technique [0002] At present, shooting panoramic videos (including taking photos, video recordings, and live broadcasting) is usually done by hand-held panoramic shooting equipment. When shooting on the move, due to unstable hands, the rotation posture of the panoramic shooting equipment will be unstable, resulting in unstable images. The picture is unstable when watching, and the user experience is not good. [0003] The purpose of image stabilization is to calculate these jitters and suppress them to achieve the purpose of video stabilization, usually by using the method of image sensor. This technology has been widely used in automotive monitoring systems and ship-borne video imaging systems for video anti-shake processing to obtain smooth and stable video i...
