Abstract: front page image
(EN) The embodiment of the invention discloses an image processing method and a device. The method comprises the steps of extracting at least one image feature point from a target frame image shot by a camera; on the condition that the target image frame is a valid frame image, acquiring the feature information of at least one optical flow image feature point in the above frame image shot by the camera, and determining an image feature point corresponding to the optical flow image feature point out of the at least one image feature point in combination with the feature information of the at least one image feature point; calculating the displacement distance between the optical flow image feature point of the previous frame image and the corresponding image feature point in the target frame image in the frame image; on the condition that the target frame image is shot in the non-motion state according to the displacement distance, outputting the target frame image. According to the embodiment of the invention, the problem that the effect of output images is poor can be solved. The image processing efficiency of the image processing device is improved.
(ZH) 本发明实施例公开了一种图像处理方法及装置,该方法包括:在摄像头拍摄到的目标帧图像中提取得到至少一个图像特征点;在所述目标帧图像为有效帧图像的情况下,获取所述摄像头拍摄到的上一帧图像中至少一个光流图像特征点的特征信息,并结合所述至少一个图像特征点的特征信息在所述至少一个图像特征点中确定与所述光流图像特征点对应的图像特征点;计算所述上一帧图像中的光流图像特征点与所述目标帧图像中对应的图像特征点在帧图像中的位移距离;在根据所述位移距离确定所述目标帧图像为非运动状态下拍摄到的情况下,输出所述目标帧图像。采用本发明实施例,可以避免输出成像效果不佳的图像的问题,能够提高图像处理装置处理图像的效率。
