Abstract:
The present invention provides a method and an apparatus for focusing, applied in image processing field, enabling a terminal in an automatic focusing process not to suspend automatic focus function. The method includes: determining an imaging mode switched from a first picture taking device in a first imaging mode to the first picture taking device or a second picture taking device in a second imaging mode, estimating a second position of the target object in the second imaging mode according to a first position of a target object in the first imaging mode and a principle of epipolar geometry, and searching for the target object in the second imaging mode according to the estimated second position of the target object in the second imaging mode.

Claim (Index 10):
The method according to  claims 1 , wherein, before the estimating the second position of the target object in the second imaging mode, the method further comprises:\n when the first picture taking device in the first imaging mode and the second picture taking device in the second imaging mode are on a same imaging plane, and when the picture taking device in the first imaging mode and the second picture taking device in the second imaging mode are horizontally offset, transforming coordinates of a pixel (u L , v L ) on a left picture taking device from the first picture taking device in the first imaging mode and the second picture taking device in the second imaging mode to (u\u2032 L , v\u2032 L ), and transforming coordinates of a pixel (u R , v R ) on a right picture taking device of the first picture taking device in the first imaging mode and the second picture taking device in the second imaging mode to (u\u2032 R , v\u2032 R ):\n [ u\u2032 L , v\u2032 L , 1 ]=K\u00b7K L \u22121 \u00b7[u L , v L , 1] T , \n [ u\u2032 R , v\u2032 R , 1 ]=K\u00b7K R \u22121 \u00b7[u R , v R , 1] T ; \n wherein before the transforming, a camera matrix of the left picture taking device is K L = [ f x L 0 c x L 0 f y L c y L 0 0 1 ] , a camera matrix of the right picture taking device is K R = [ f x R 0 c x R 0 f y R c y R 0 0 1 ] , (f x L , f y L ) are coordinates of a focal point of the left picture taking device, (f x R , f y R ) are coordinates of a focal point of the right picture taking device, (c x L , c y L ) are coordinates of a principal point of left picture taking device, and (c x R , c y R ) are coordinates of a principal point of right picture taking device; and\n wherein after the transforming, a new camera matrix of the left picture taking device and a new camera matrix of the right picture taking device are \n K = [ f 0 c x 0 f c y 0 0 1 ] , where f is a transformed focal length, and (c x , c y ) are coordinates of a transformed principal point.
