为了获得更好的激光雷达图像融合效果,提高图像融合质量,提出一种基于小波变换的激光雷达图像融合方法。首先采用小波变换对激光雷达图像进行分解,得到不同频率的小波系数,然后对低频小波系数进行加权,选择高频小波系数实现激光雷达图像融合,最后采用仿真实验对其性能进行分析。结果表明,相对于当前经典激光雷达图像融合方法,本文方法的激光雷达图像融合结果的主观和客观质量均更优,完全可以满足激光雷达图像实际应用的需求,具有较高的实际应用价值。
In order to obtain a better fusion effect of Lidar images and improve the image fusion quality, a fusion method of Lidar images based on wavelet transform is proposed. Firstly, the wavelet transform is used to decompose the lidar image to obtain the wavelet coefficients with different frequencies. Then the low frequency wavelet coefficients are weighted and the high frequency wavelet coefficients are selected to realize the fusion of the laser radar image. Finally, the performance of the laser radar image fusion is analyzed. The results show that compared with the current LIDAR fusion method, the subjective and objective quality of the LIDAR fusion method is better than the conventional Lidar fusion method, which can satisfy the practical application of LIDAR images and has high practical value.
