Embodiment Construction

[0031] Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0032] CCD camera can be used in detection device, needs the position and the performance parameter of each CCD camera to be adjusted well before detection, and the target of the present invention can be used for adjusting and detecting the position and performance parameter of one or more CCD cameras, at first will The multifunctional target is placed on the carrier, and the CCD camera is also placed accordingly, and then the target graphic signal captured by the CCD camera is input to a computer or an oscilloscope for observation, and then the position and performance parameters of the CCD camera are adjusted and quantitatively detected.

[0033] Referring to Fig. 1, it is a schematic diagram of the basic group of multifunctional targets of the present invention, the basic group of graphics is attached to a plane or cylindrical carrier, as ...

Abstract

The invention discloses a multifunctional target, which includes one or more basic group figures, and the multifunctional target is attached to a plane or cylindrical surface carrier, and the multifunctional target of the present invention can be conveniently, quickly and accurately Adjust and detect the position and performance parameters of each CCD camera.

Description

technical field [0001] The invention relates to a detection device, in particular to a multifunctional target for adjusting and detecting the position and performance parameters of a camera. Background technique [0002] At present, CCD cameras are widely used in science and technology and industrial production for real-time measurement and monitoring; in addition, in order to expand the detection range, multiple CCD cameras are often used to work simultaneously. For these CCD cameras, in addition to debugging one by one, the spatial positions of all CCD cameras must be adjusted accurately; at the same time, it is also hoped to measure the main performance indicators of each CCD camera. [0003] In the prior art, there are collimator adjustment methods, theodolite adjustment methods, and image adjustment methods. [0004] In the collimator adjustment method, for a CCD camera, use a small-diameter collimator with a discrimination rate plate for measurement, and observe the i...
