Title:
METHOD AND DEVICE FOR IMPROVING DEPTH INFORMATION OF 3D IMAGE, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/033777
Kind Code:
A1
Abstract:
A method for improving depth information of a 3D image. The method comprises: obtaining an original 3D image frame, performing a first exposure on the original 3D image, and generating a first exposed image; if the number of effective pixels in the first exposed image meets a preset condition, extracting the effective pixels in the first exposed image; otherwise, continuously exposing the original 3D image, generating a corresponding exposed image, and determining whether the number of effective pixels in the exposed image meets the preset condition, until the exposure time reaches an exposure time threshold or the number of effective pixels in a corresponding image generated by exposure meets the preset condition, and extracting the effective pixels in the corresponding image; and calibrating and correcting the effective pixels to generate a 3D depth information map. Also provided are a device for improving depth information of a 3D image, and an unmanned aerial vehicle. By extracting effective pixels in an exposed image meeting a condition after multiple exposures to generate a 3D depth information map, the quality of a 3D image is improved.
