Abstract

The invention discloses a visual inertia calibration method and device, and belongs to the technical field of vision. The method comprises the following steps: acquiring image data acquired by an image sensor of the electronic equipment and attitude data acquired by an inertial measurement unit of the electronic equipment in a process of driving the electronic equipment to rotate according to target motion parameters through a displacement table; determining a parameter value of a calibration parameter according to the image data, the attitude data and the target motion parameter based on a set constraint condition reflecting a relationship among the image data, the attitude data and the target motion parameter; wherein the calibration parameters are parameters for performing anti-shake compensation on image data acquired by the image sensor through attitude data acquired by the inertial measurement unit; and storing the determined parameter value in the electronic equipment for carrying out the anti-shake compensation.
