The technology of binocular camera matures day by day. Compared with monocular camera, it can obtain higher resolution images at a lower cost than monocular cameras. However, existing high dynamic range methods based on images acquired by monocular camera, causing the result images to be noisy and blurry. In order to solve the problem, this paper presents a new high dynamic range method based on monochrome-color camera system. We first use the camera system to obtain multiple sets of different exposure monochrome-color image pairs, and then match the same exposure image pair. By using the color propagation methods, we combine the color information from color image with detail information from monochrome image, and obtain multiple sets of different exposures, sharper, low-noise images with more details. And finally get the result through high dynamic imaging and tone mapping. Experiments show that our method is better than the results of the classical method.
