An embodiment of the invention discloses a video processing method, device and system. According to the invention, a camera device provided with a gyroscope can be calibrated based on a Rodrigues rotation matrix and then the calibration parameters are obtained. Then first video information and first gyroscope rotation information can be obtained and the first video information is subjected to stabilization treatment and/or rolling shutter effect removing treatment according to the calibration parameters and the first gyroscope rotation information. By adopting the scheme, the robustness can be improved. Besides, the calculation complexity is low and video treatment can be performed with less occupancy of computation resources. Video quality can be improved.
