Problems solved by technology

At present, in the case of the same wide detection field of view, in order to achieve high-resolution visual inspection effects and more accurate detection capabilities, it is often achieved by using high-pixel CCDs, but due to the high price of high-pixel CCDs, it is not reasonable Economical application to actual production
Even if the economy allows, due to the bottleneck of current technology, it is impossible to obtain high-pixel CCDs that exceed current technology to obtain high-resolution images

Embodiment 1

[0038] Such as Figure 5 As shown, the outline is Figure 6 The object 10 shown is imaged in the first CCD 701 through the first imaging optical path 901 and the first detection lens 801 to obtain the following Figure 7 The first CCD image shown in the first CCD image includes the image of the overlapping area 1102 of the measured object and the image of the scanning area 1103 on the left side of the measured object, and the image of the overlapping area 1102 of the measured object is binarized 0-255 , that is, set the standard value to 150, and the images with a brightness higher than 150 in the image of the overlapping area 1102 of the measured object (indicated by "X" in the overlapping area) will change to 255 brightness information, and the image of the overlapping area 1102 of the measured object has a brightness lower than The image of 150 (indicated by the "+" in the overlapping area) becomes 0 brightness information, and the following is obtained: Figure 9 The fir...

Abstract

The invention relates to a multi-CCD spliced scanning mechanism and an image processing method through the same and belongs to the technical field of machine vision processing. The mechanism comprises a fixation support, a fixation plate is fixed on the fixation support, a first CCD and a second CCD are arranged on the fixation plate in parallel, a first detection lens is fixed at the bottom of the first CCD, a second detection lens is fixed at the bottom of the second CCD, a first LED shiner and a second LED shiner are arranged below the first detection lens and the second detection lens in a fit mode and are disposed on the two sides of an imaging light path of the first LED shiner and the second LED shiner, and an object to be measured is arranged below the first LED shiner and the second LED shiner in a fit mode. By means of the mechanism and the method, within the controllable cost, the better resolution can be obtained for equally detected wide-view objects to be detected, and the mechanism and the method can be applied to actual production requirements reasonably.

Description

technical field [0001] The invention belongs to the technical field of machine vision image processing, and in particular relates to a multi-CCD mosaic scanning mechanism and an image processing method using the mechanism. Background technique [0002] At present, in the field of machine vision image processing, line scan cameras are more and more widely used. Therefore, how to achieve the optimal matching scheme of the entire system while reducing the cost as much as possible is also receiving more and more attention. At present, in the case of the same wide detection field of view, in order to achieve high-resolution visual inspection effects and more accurate detection capabilities, it is often achieved by using high-pixel CCDs, but due to the high price of high-pixel CCDs, it is not reasonable Economical application to actual production. Even if the economy permits, due to the bottleneck of current technology, it is impossible to obtain high-pixel CCDs that exceed curre...
