Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] A method for locating a shooting location of a sunlight image forming video, comprising the following steps:

[0035] (1) Select the upright object in the video as a reference object, set its height as h, and the length of its shadow as l, and draw a comparison curve of the length of shadow l changing with time t according to the change of shadow in the video;

[0036] (2) Determine the shooting time as t s , the altitude angle of the sun at the time of shooting is α, and the latitude of direct sunlight is δ when shooting, a...

Abstract

The invention discloses a sunlight shadowing video shooting location positioning method. The method includes following steps: determining shooting time as, sun height angle during shooting as and sundirect-irradiation latitude during shooting as and assuming longitude and latitude of a shooting location as; according to a triangular relation of height and shadow length, acquiring assumed shadow length, and assuming Beijing time as reference time to acquire an expression function showing change of the assumed shadow length along with time; drawing an assumed curve showing change of the shadowlength along with time according to the function in the step (3); comparing the assumed curve in the step (4) with a contrast curve in the step (1), if the assumed curve is fitted with the contrast curve, executing the step (6), and if not, resetting longitude and latitude and returning to the step (3); predicating a location where video is shot according to the longitude and the latitude.

Description
