The invention discloses a parallax image splicing method and system based on template matching and feature clustering. The parallax image splicing method comprises the steps: obtaining a source imageand a target image; determining an overlapping region of the source image and the target image by adopting a template matching method; adopting a feature point pair screening method based on local matching information in the overlapping area, and screening a correct feature point pair set; performing clustering segmentation on the screened correct feature point pair set to obtain a local homography matrix model; and performing image registration and splicing according to the local homography matrix model. By adopting the parallax image splicing method or the parallax image splicing system provided by the invention, the image overlapping region can be quickly positioned, so that the external point interference and the calculation cost are reduced, and enough matching point pair informationcan be extracted from the parallax image, and the local accurate alignment and parallax processing of the image are realized. And finally, the parallax image splicing method is integrated into a corresponding system, so that the parallax image splicing method can be accurately operated and implemented.
