The invention provides a vision and satellite positioning sensor joint calibrating method suitable for robot navigation. The vision and satellite positioning sensor joint calibrating method comprises the steps of: ensuring that each frame of image of a center point of a satellite positioning sensor antenna in a vision sensor is visible during assembly; acquiring a front-stage correction result of the vision sensor, a straight line distance between the vision sensor and the satellite positioning sensor antenna, and coordinates of the center point of the satellite positioning sensor antenna in an image surface coordinate system of a certain frame of image, solving absolute values of the coordinates of the center point of the satellite positioning sensor antenna in a camera center coordinate system and plus and minus of all items; determining coordinates of an original point of the camera center coordinate system in an equivalent coordinate system; and solving a longitude, a latitude and a height of the original point of the camera center coordinate system based on a longitude, a latitude and a height measured by a satellite positioning sensor at every sampling moment so that errors caused by assembling centers of the satellite positioning sensor and the vision sensor in different space points are jointly calibrated.
