The prototype
The idea is simple: rotate a linear polarization filter in front of the lens and capture an image at 0, 45, 90 and 135 degrees. Then do some math wizardry to calculate the angle of polarization based on the difference in luminance between the 4 pictures. This is how it looks:
What is it good for?
There are a number of ways a polarimetric camera is useful in computer vision. It can remove reflections, detect stress in certain materials and detect scratches. For more information on what the industry is doing see this page.
I like it for the aesthetics mostly and I have another project where I used one as a microscope. But I've also found it opens up some unique possibilities like extreme low light imaging, high definition 3D reconstruction of scenes and automatic HDR imaging. I've been able to read fingerprints at 1 meter from the sensor, create alien landscapes out of sugar and detect focus changes in my eyes, to name a few.
This video is showing the prototype of the camera I am looking for the fully completed camera which is ready to use. I am being an https://essayreviewuniverce.com/essayhave-review/ writing service blog photographer this camera will help me in my work and even make my work easy as it is having automated mode which shoots by its own if we set instructions to it.
