Embodiment

[0059] Before the focusing method and / or focusing device of the present invention are implemented (implementation preparation stage), the third coordinate of the first optical center D and the fourth coordinate of the second optical center E are preset, that is, Preset the positions of the first camera and the second camera of the user equipment (for example, mobile phone, tablet computer, etc.), so as to set the third position of the first optical center D of the first camera. coordinates and the fourth coordinate of the second optical center E of the second camera. Wherein, the third coordinate and the fourth coordinate are coordinates in the first three-dimensional coordinate system.

[0060] During the implementation of the focusing method and / or focusing device of the present invention, the first camera shoots the subject 101 to generate the first imaging data, and the second camera takes pictures of the subject 101 shooting to generate the second imaging data.

Abstract

The invention discloses a focusing method and device. The method comprises the following steps: A, using a first camera and a second camera to obtain first imaging data and second imaging data of an object to be captured; B, according to the first imaging data and the second imaging data, identifying a first imaging position point and a second imaging position point of the object on a first reference plane and a second reference plane; C, calculating a first distance, a first angle and a second angle on the basis of the first imaging position point, the second imaging position point, a first light center and a second light center; D, according to the first distance, the first angle and the second angle, calculating a second distance, which is the distance between the object and the first imaging position point, and / or a third distance, which is the distance between the object and the second imaging position point; and E, focusing according to the second distance and / or the third distance. The method and the device can focus precisely.

Description

【Technical field】 [0001] The invention relates to the technical field of photographing, in particular to a focusing method and device. 【Background technique】 [0002] The traditional autofocus technical solutions are: [0003] The distance sensing unit senses the distance between the lens module and an object, and the controller judges whether the lens module is in far focus or near focus according to the distance between the lens module and the object sensed by the distance sensing unit, and the shooting When the distance is greater than the close focus focus depth of the lens module lens, it is far focus, otherwise, it is close focus. [0004] In practice, the inventors found that the prior art has at least the following problems: [0005] The above-mentioned traditional technical solutions cannot achieve accurate focusing. 【Content of invention】 [0006] The object of the present invention is to provide a focusing method and device, which can realize precise focusing...
