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] Such as 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 ...

Abstract

The invention provides a reference positioning method for a CCD camera. The method corrects two CCD cameras at the same time. The first CCD camera and the second CCD camera are placed on a platform, and the lenses of the first CCD camera and the second CCD camera are perpendicular to each other. downward, and a certain distance from the platform; correct the verticality of the first CCD camera and the second CCD camera; place a horizontal ruler directly below the first CCD camera and the second CCD camera after correcting the verticality; Both a CCD camera and a second CCD camera capture the images of the spirit level, and transmit the images to a PC for processing, and adjust the position of the first CCD camera or the second CCD camera according to the processing results until the first CCD camera and the second CCD camera are completed. Correction of the relative positions of the two CCD cameras. The reference positioning method of the invention is simple and has high 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...
