Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, 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 creative efforts fall within the protection scope of the present invention.

[0024] like Figure 1 to Figure 4 A reference positioning method of a CCD camera shown, the method simultaneously corrects two CCD cameras, including the following steps:

[0025] Step 1: place the first CCD camera and the second CCD camera on the platform, the lenses of the first CCD camera and the second CCD camera are vertically downward, and a certain distance from the platform;

[0026] Step 2: Correct the verticality of the first CCD camera and...

Abstract

The invention provides a reference positioning method of CCD (Charge Coupled Device) cameras. The method comprises the steps of simultaneously correcting the two CCD cameras, placing the first CCD camera and the second CCD camera on a platform, allowing lenses of the first CCD camera and the second CCD camera to be perpendicularly downward and have certain distances from the platform, correcting the perpendicularity of the first CCD camera and the second CCD camera, horizontally placing a leveling rod under the first CCD camera and the second CCD camera, allowing the first CCD camera and the second CCD camera to shoot images of the leveling rod, transmitting the images to a PC (Personal Computer) for processing, and adjusting a position of the first CCD camera or the second CCD camera according to a processing result until correction of a relative position of the first CCD camera and the second CCD camera is completed. The reference positioning method is simple and high in accuracy.

Description

technical field [0001] The invention relates to the field of reference positioning, in particular to a reference positioning method of a CCD camera. Background technique [0002] The CCD camera has the advantages of high acquisition rate and wide field of view. It is generally used in high-speed scanning and high-precision detection systems. The relative pose of the CCD camera and the detected object not only affects the scanning range of the camera, but also affects its scanning accuracy. In turn, the CCD camera needs to be adjusted. Perform benchmark positioning. At present, there are traditional camera calibration methods, camera self-calibration methods and active vision camera calibration methods for CCD camera calibration methods. The traditional camera calibration method needs to be realized through calibration objects. It is limited, and two or more images must be used for calibration, which is complicated to use; the camera self-calibration method can directly cali...
