The embodiment of the invention relates to the technical field of automatic focusing, in particular to a focusing method, which is characterized by comprising the following steps: when a plurality of focusing conditions meet a preset standard, acquiring phase information from a phase focusing module and depth information from an obstacle avoidance module, the depth information is information reflecting the distance between the unmanned aerial vehicle and an obstacle; acquiring a first object distance according to the phase information; acquiring a second object distance according to the depth information; when both the phase information and the depth information are invalid information, judging whether the terrain clearance of a shooting lens is greater than a preset height threshold value or not; if yes, focusing the far focus; and if not, focusing is not carried out. By fusing various focusing judgment conditions and combining and using phase information and depth-of-field information, the problem of easy out-of-focus in a specific scene is effectively solved, and a relatively high focusing speed can also be realized.
本申请实施例涉及自动对焦技术领域,尤其涉及一种对焦方法,其特征在于,包括:在若干项对焦条件均满足预设标准时,获取来自相位对焦模块的相位信息以及来自避障模块的深度信息,所述深度信息为反映无人机与障碍物之间的距离的信息;根据所述相位信息获取第一物距;根据所述深度信息获取第二物距;当所述相位信息和所述深度信息均为无效信息时,判断拍摄镜头的离地高度是否大于预设高度阈值;若是,对远焦点进行对焦;若否,则不进行对焦。其通过融合多种对焦判断条件以及结合使用相位信息和景深信息,有效的解决了特定场景下容易失焦的问题,还能够实现较快的对焦速度。
