Abstract
The invention provides a real-time video image stabilization method based on time sequence registration, and belongs to the technical field of video image processing. The provided technical scheme is that a time matching technique is led in when real-time stabilization control of a video image is carried out. The method concretely comprises the steps of: firstly, storing vibration parameter data measured by a vibration measuring unit into a sequence group according to a time sequence, then checking whether the image (after being adjusted by the vibration data corresponding to a serial number) meets the requirement of stable output by fuzzy adjustment, if not, gradually investigating and detecting according to the serial number which solely corresponds to different vibration data in the sequence group, so as to obtain the vibration parameter data capable of ensuring that a final output effect of the video image is the best. Thus, the real-time video image stabilization method is not restricted by the condition of an image processing algorithm in the prior art, and the image with the high stabilization precision of a stable platform is obtained.
