Title:
METHOD AND APPARATUS FOR DETERMINING SPATIAL PARAMETER BY USING IMAGE, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/012269
Kind Code:
A1
Abstract:
A method and an apparatus for determining a spatial parameter by using an image, and a terminal device are used for conveniently determining an actual size of a photographed object in an image by using the image. The method comprises: determining corresponding first pixel coordinates on an image displayed on a display device and corresponding second pixel coordinates on the image (S101); determining a corresponding image distance between the first pixel coordinates and the second pixel coordinates (S102); and determining a corresponding spatial parameter between the first pixel coordinates and the second pixel coordinates according to the image distance, an object distance obtained when the image is taken, and a focal length of a lens of a photographing apparatus that takes the image (S103). The method can conveniently determine a spatial parameter of a photographed object in an image by using the image on a display device, quantify an actual size of the photographed object by using the image, and avoid that the actual size of the photographed object is compared by setting a reference object on the image, thereby improving user experience.
