针对数字动画图像畸变校正能力低的问题,提出了基于差值映射的数字动画图像畸变校正方法。构建数字动画图像的畸变特征检测模型,结合颜色概率分布与数字动画图像解析参数,得到多维度下的畸变特征检测结果。根据数字动画图像畸变特征检测结果,计算数字动画图像的纹理特征和颜色特征。采用差值映射方法,进行数字动画图像畸变校正。仿真结果表明:采用该方法进行数字动画图像畸变校正的误差较小,成像质量较高。

Due to the low ability of digital animation image distortion correction, a digital animation image distortion correction method based on difference mapping is proposed. The distortion feature detection model of digital animation image is established. The color probability distribution and digital animation image are combined to analyze parameters, and the distortion feature detection results in multi-dimensional are obtained. According to the distortion feature detection results of digital animation image, the texture features and color features of digital animation image are calculated. The difference mapping method is used to correct the distortion of digital animation image. The simulation results show that the method for digital animation image distortion correction has smaller error and higher imaging quality.
