Abstract:
1. An apparatus for interpreting an image position, using cameras to take a photo of an image so as to obtain a position of a target, comprising: a first camera provided with a first lens and used for taking a photo of an image; a second camera provided with a second lens and used for taking a photo of an image; a first reflection mirror positioned in a visual angle range of said first lens, and used for reflecting an image of a target to said first lens to be taken a photo by said first lens as a first image in an image of said first reflection mirror; a second reflection mirror positioned in a visual angle range of said second lens, and used for reflecting an image of the target to said second lens to be taken a photo by said second lens as a second image in an image of said second reflection mirror; and a microprocessor electrically connected with said first and said second cameras, and used for processing said first and said second images respectively and obtaining a relative coordinate of said target in a range of an operation plane by means of operational analysis; wherein said first and said second cameras have a horizontal axis respectively parallel to said operation plane; that is, a coordinate system, which is corresponding to said first and second cameras respectively, has an x′z′ plane, and a coordinate system, which is corresponding to said operation plane, has an xz plane at which said operation plane is located being parallel to the x′z′ plane; wherein said microprocessor relies on analyzing a level distance between said first and second images relative to images of said first and second reflection mirrors taken a photo by said lenses to obtain a relative coordinate value of said target on said xz plane.
