Method for capturing a size of an installation space for a door or window

摘要

A method for capturing a size of an installation space for a door/window using remote image includes providing an installation space for a door/window (10) having an edge (10a), disposing a size-calibrating member (20) at one side of the edge (10a) of the installation space for the door/window (10), using an image capturing device (30) to acquire an image (40) that contains with the installation space for the door/window (10) and the size-calibrating member (20), transmitting mentioned image (40) to an image measurement system (50), using the image measurement system (50) to analyze the image (40) and determine an image ratio between the installation space for the door/window (10) and the size-calibrating member (20), and a practical size of the installation space for the door/window (10) can be figured out based on mentioned image ratio and a practical size of the size-calibrating member (20).
