Abstract

The invention provides a ToF-based microspur focusing method. The method is suitable for a shooting device with a ToF camera and an RGB camera with a zooming function, and comprises the following steps: S1, adjusting a viewing frame to align to a to-be-shot three-dimensional scene in a microspur mode, S2, obtaining a depth image of the three-dimensional scene through the ToF camera, and obtainingdepth information and an object contour of an object in the three-dimensional scene through calculation, S3, determining a shooting main body in the three-dimensional scene through a preview functionof the RGB camera, and S4, controlling the RGB camera to focus on the shooting main body according to the distance between the shooting main body and the ToF camera acquired by the ToF camera. Compared with the prior art, the ToF-based microspur focusing method provided by the invention has the advantages that the focusing speed is high, the outline of the object in the shot image is clear and accurate, and the accuracy of the blurring effect is ensured, so that the shooting effect is improved. The invention also provides a ToF-based microspur shooting method and device.

Description

technical field [0001] The invention relates to the field of macro photography, in particular to a ToF-based macro focusing method, a macro photography method and a photography device thereof. Background technique [0002] With the rapid development of the mobile Internet, mobile devices such as mobile phones have gradually become inaccessible personal items in people's lives. The lightweight feature has gradually replaced the bulky and single-function traditional professional cameras. [0003] However, compared to traditional professional cameras that achieve fast focusing based on the focus sensor, mobile phones are usually small in size and inconvenient to install a dedicated focus sensor. As a result, there is still a big gap in the camera function of mobile phones compared with traditional professional cameras, especially in macro photography. The accuracy, accuracy and speed of shooting are difficult to match with traditional professional cameras. [0004] The Chines...
