OBTAINING DISTANCE BETWEEN DIFFERENT POINTS ON AN IMAGED OBJECT
摘要
The present invention discloses an image capturing apparatus and a method for obtaining the distances between different points of an object to be shot during image capturing of said object. The method comprises: determining a pair of specified points on the object for distance measurement; focusing on each specified point respectively, and obtaining a focal length for obtaining a clear image of the specified point on an imaging device of an image capturing apparatus, a distance between the clear image point of the specified point and a longitudinal axis of a convex lens of the image capturing apparatus, and a distance between the convex lens and the imaging device of the image capturing apparatus during said focusing; and calculating a distance between the specified points in the pair on the object.
