These video records are used as the evidence of traffic dispute or used to report the bad driving behavior. They also used to record the landscape when they are driving as the travel memories.
The shot videos would make the viewer hard to recognize the video content when they are shaking seriously due to the bumpy road. Therefore, they will not keep these records.
In this thesis, a compensation mechanism accomplished by simultaneously recording the video from camera and rotating angles from sensors. Then the data of rotating angles are used to compensate the original recorded videos. The compensated video shows the fixed objects and moving view range. And it will give comfort to the viewer.
This compensation mechanism can reduce the vibration and displacement of picture reduced from original video. The reduction capability is about 29% in vertical offset, about 47% in horizontal offset and about 19% in rotating angle, respectively.
