Vehicle-mounted panoramic spliced image vignetting correction method

The invention provides a vehicle-mounted all-round stitching image vignetting correction method, and belongs to the technical field of vehicle all-round monitoring, and the method specifically comprises the steps: obtaining the initial weight of an image; acquiring a real-time dynamic weight of the image; establishing a global fixed vignetting weight of the image; obtaining a global dynamic vignetting weight according to the fixed vignetting weight and the dynamic vignetting weight; and correcting the image by using the global dynamic vignetting weight to obtain a corrected output image. According to the processing scheme, the excessive imbalance phenomenon at the splicing seam is accurately eliminated. 本申请提供了一种车载环视拼接的图像暗角矫正方法，属于车辆环视监控的技术领域，具体包括：获取图像的初始权重；获取图像的实时动态权重；建立图像全局的固定暗角权重；根据固定暗角权重和动态暗角权重，得到全局动态暗角权重；利用全局动态暗角权重对图像进行矫正，得到矫正后的输出图。通过本申请的处理方案，准确的消除拼接缝处的过度不均衡现象。
