摘　　要：多路传感器传输图像自动配准,能够获取高精度传感器图像。对传输图像配准时,需要在配准前对图像进行增强,计算图像配准参数,完成传输图像的自动配准。传统方法采用球面成像模型获取图像,将深度图与完成信息提取之后的图像进行配准,但忽略了计算图像配准参数,导致配准系数低、耗时长。提出基于区域选择的多路传感器传输图像自动配准方法,利用软阈值法对小波系数缩减去噪,于不同尺度实现分解系数增强。针对高频子带和低频子带图像实行非线性处理,提高图像对比度,完成多路传感器传输图像增强。重复提取图像特征,得到图像配准点对。使用结构相似度最大的配准点来计算图像配准参数,实现图像自动配准。仿真结果表明,上述方法平均配准耗时短,图像配准系数较高。与当前相关方法比较,所提方法可提高图像配准效率与精度,可行性和可靠性强。In the traditional method,the spherical imaging model was used to obtain the image,but the image registration parameters were not calculated,which results in low registration coefficient and high time consumption.Therefore,an automatic registration method for transmission image of multichannel sensor based on region selection was proposed. Firstly,the soft threshold method was used to reduce the noise of wavelet coefficient,and the decomposition coefficient was enhanced at different scales. Meanwhile,the nonlinear processing for high-frequency sub-band image and low-frequency sub-band image could improve image contrast and enhance image transmitted through multi-channel sensor. The image feature was extracted repeatedly to obtain the registration point pair. Moreover,the registration point with the largest structural similarity was used to calculate image registration parameters. Thus,the automatic registration of image was realized. Simulation results verify that the proposed method has short average registration time and high image registration coefficient. Compared with the current methods,the proposed method can improve the efficiency and accuracy of image registration,which has strong feasibility and reliability.
