英文摘要: The invention relates to a real-time video image arbitrary angle rotation system and a control method thereof. The system comprises a video image access control unit and a reverse coordinate calculation unit, wherein the input end of the video image access control unit is connected with image data and reverse coordinate data, and the output end of the video image access control unit is connected to a bilinear interpolation calculation unit the input end of the reverse coordinate calculation unit is connected with rotational angle data, and the output end of the reverse coordinate calculationunit is connected to the video image access control unit and the bilinear interpolation calculation unit the input end of the bilinear interpolation calculation unit is connected with the image dataand the reverse coordinate data, and the output end of the bilinear interpolation calculation unit is connected to a system image data output interface. The method comprises the following steps of: receiving the image data and the rotational angle data input by the system storing the image data input by the system according to reverse coordinate data output by the reverse coordinate calculation unit and carrying out bilinear interpolation calculation on the image data and the reverse coordinate data, and outputting a result to the image data output interface. The invention realizes a rapid calculation structure which is easily realized by a programmable logic device and has the advantages of low cost, high speed, strong practicability and the like.
