LIGHT-MEASURING METHOD AND DEVICE, EXPOSURE METHOD AND DEVICE, AND UNMANNED AERIAL VEHICLE

Document Type and Number:

WIPO Patent Application WO/2018/119590

Kind Code:

A1

Abstract:

A light-measuring method and device, exposure method and device, and unmanned aerial vehicle. The light-measuring method comprises: dividing an acquired image under test into several light measurement regions, and determining a weight value for each of the light measurement regions, wherein the several light measurement regions comprise a first light measurement region (WB1) located in an upper portion of the image under test and multiple other light measurement regions (WB2, WB3) outside of the first light measurement region, and the weight value of the first light measurement region (WB1) is greater than the weight values of the other light measurement regions (WB2, WB3) (101); and acquiring light intensity values of the several light measurement regions, and calculating, according to the light intensity values and the weight values of the several light measurement regions, light intensity values of the image under test (102). The focus of light measurement is in the upper portion of an image under test because the upper portion is normally a sky portion in an aerial photography image. In this way, the present invention performs exposure mainly according to brightness of the sky portion, thus preventing over-exposure, capturing details of clouds in the sky, acquiring superior photos, and improving photo effects.
