Abstract

本发明实施例提供一种视频编解码方法、装置、可移动平台和存储介质。其中，视频编码方法包括：获取待编码图像对应的全局运动矢量；在待编码图像中确定目标编码区域；基于全局运动矢量，在参考图像中确定与目标编码区域对应的参考区域；其中，参考图像被存储于第一存储器中；读取参考图像中的参考区域，并将参考区域存储于第二存储器中；在第二存储器中，读取参考区域的图像块；基于读取的参考区域的图像块，对目标编码区域的图像进行帧间预测操作；基于所述帧间预测操作的结果，对所述目标编码区域的图像进行编码处理。采用本发明提供的视频编解码方法，可以降低读取带宽的占用，可以高效地利用参考图像进行视频编解码处理。
