| dc.description.abstract | The science and technology are changing with each passing day. the pursuit of speed and convenience, with the in-depth advancement of industrial manufacturing, has put forward higher-level requirements in the application of industrial cameras. Ordinary industrial cameras can no longer fully meet the requirements of industrial applications. The most common example is the detection of some glass and plastics. On the general visible light image, no scratches and dirt can be seen, but under the polarized light image, it can be clearly seen; or it is a combination of medicine tablets and aluminum packaging. There may be problems such as reflection and glare. Generally, there will be wrong judgments under the test, but under polarized light, because the degree of polarization is different, it is easy to distinguish whether the lozenge is filled. It can be seen from4 the above that the polarization of light provides extremely rich information.
However, the current equipment system has the specificity of the purpose of the system. For example, an industrial polarization camera can only shoot polarized images. If there are other requirements, another system must be set up. It cannot be in the same system. Get more information.
In order to improve the information obtained and overcome the limitations of the system equipment, this research uses an improved light field camera (Light Field Camera) optical system architecture, with a linear polarizer, in an image, four different polarization angles are obtained. Image, calculate the polarization image and polarization angle of the object under test, however, it also uses the parallax advantages of the light field camera itself to reconstruct the object in the virtual space, thereby obtaining the polarization image, polarization angle, and polarization angle of the object in a system. Three-dimensional reconstruction can also apply polarized images and polarization angles to three-dimensional reconstruction to achieve multi-dimensional information presentation. | en_US |
