Improvement image processing method of holographic laser projection

全息激光投影图像采集中受到采集设备的小扰动影响,成像的模糊性较大,为了提高全息激光投影图像的成像质量,提出一种基于空间邻域边缘能量融合和亮度补偿的全息激光投影图像处理方法。首先采用激光器进行全息激光投影图像采集,对采集的图像通过多尺度差分插值方法进行像素序列提取和重构。然后采用空间邻域边缘能量融合方法进行图像亮点区域分割与信息融合,实现图像降噪处理。通过亮度补偿进行图像像素序列的小扰动抑制,实现全息激光投影图像成像优化。最后进行仿真实验分析,结果表明,采用该方法进行全息激光投影成像,具有较好的激光成像视觉效果,图像的输出信噪比较高,降噪能力较强。

The fuzziness of imaging is high when the holographic acquisition equipment affected by small disturbance. In order to improve the imaging quality of holographic laser projection image,this paper proposed a processing method of holographic laser projection image based on spatial neighborhood edge energy fusion and brightness compensation. Firstly,the holographic laser projection image is acquired by using the laser,and the image is extracted and reconstructed by the multi-scale difference interpolation method. Then,the spatial neighborhood edge energy fusion method is used to segment the image and fuse the information. The small disturbance suppression of image pixel sequence is realized by brightness compensation,and the holographic laser projection image is optimized. At last,the simulation results show that the method has a better visual effect of laser imaging,and the output SNR is high,and the denoiseing ability is stronger.
