Abstract:
The present disclosure provides a mobile terminal image synthesis method, a mobile terminal image synthesis apparatus and a mobile terminal. The mobile terminal image synthesis method includes: acquiring a first fisheye image collected by a front fisheye camera group and a second fisheye image collected by a rear fisheye camera group; obtaining a first correction image by using a first internal parameter of the front fisheye camera group to correct the first fisheye image, and obtaining a second correction image by using a second internal parameter of the rear fisheye camera group to correct the second fisheye image; and obtaining a synthetic image by splicing and combining the first correction image and the second correction image according to splicing parameters.

Claim (Index 3):
The method of  claim 2 , wherein the determining the first internal parameter of the front fisheye camera group and the second internal parameter of the rear fisheye camera group, includes:\n when rotating the mobile terminal around a vertical axis or a horizontal axis of the mobile terminal, obtaining each frame fisheye-image of the checkerboard collected by the front fisheye camera group and each frame fisheye-image of the checkerboard collected by the rear fisheye camera group, respectively, wherein all or parts of the checkerboard is in the view angle of at least one of the front fisheye camera group and the rear fisheye camera group all the time; determining, by a gyroscope of the mobile terminal, a first rotation angle of the mobile terminal when the front fisheye camera group collects each frame fisheye-image of the checkerboard and a second rotation angle of the mobile terminal when the rear fisheye camera group collects each frame fisheye-image of the checkerboard, respectively; and obtaining the first internal parameter through calculation according to a projective reconstruction calibration algorithm based on each frame fisheye-image of the checkerboard collected by the front fisheye camera group and the first rotation angle, and obtaining the second internal parameter through calculation according to the projective reconstruction calibration algorithm based on each frame fisheye-image of the checkerboard collected by the rear fisheye camera group and the second rotation angle.
