Binocular image fusion method and system and terminal equipment

The invention provides a binocular image fusion method and system and terminal equipment. According to the binocular image fusion method provided by the invention, the positions of the first picture content data and the second picture content data can be dynamically adjusted according to the splicing control information, so that the size of a field angle is dynamically adjusted, and a dynamic binocular fusion picture is matched. Besides, the design parameters of the two optical systems for respectively projecting the first picture content data and the second picture content data are the same, and the first picture content data and the second picture content data move in the same object plane of the corresponding optical systems. The moving distances of the first picture content data and the second picture content data are the same and the directions are opposite. By means of the design, it can be ensured that the overlapping areas of the first picture content data and the second picture content data have the
