The embodiment of the invention discloses a depth-of-field detection method and device, a storage medium and a terminal, and the method comprises the steps: collecting a first image of a target shooting object through a camera when a reflector is located at a first angle; when the reflector is located at a second angle, collecting a second image of the target shooting object through the camera, wherein the first angle is not equal to the second angle; acquiring image difference information between the first image and the second image; obtaining the current focal length of the camera; and determining depth-of-field information of the target shooting object at least according to the image difference information, the focal length, the first angle and the second angle. According to the scheme,the depth-of-field information of the measured object can be detected only by adjusting the angle of the inner reflector of the single camera, other equipment does not need to be additionally arranged for cooperation, and the internal structure of the shooting equipment is simplified while the detection accuracy of the depth-of-field information is guaranteed.
Description
technical field [0001] The present application relates to the technical field of information processing, and in particular to a depth detection method, device, storage medium and terminal. Background technique [0002] With the continuous development of science and technology, more and more depth information detection has entered the electronic products used in daily life, and how to obtain depth information simply and conveniently has become a hot topic of concern. [0003] In related technologies, it is necessary to add a special depth detection module to the shooting device, such as a TOF (time offlight, time of flight) module or a structured light module, and to overlap the depth information with the scene captured by the camera alone to obtain the depth information of each scene in the shooting area. Depth information between scenes. However, this method needs to be used simultaneously with other devices (such as an RGB camera), and the internal structure design of the...
