Basic image processing for gases visualization with python and the opencv computer vision library. this process is called synthetic schlieren and has the advantage of being much easier to apply than traditional techniques because it does not need mirrors or lenses.

Pdf Natural Background Oriented Schlieren Imaging A schlieren digital imaging system is described using a webcam and the background oriented method. the system hardware and minimum python scripts using opencv are detailed. Bos is a line of sight imaging technique and measures locally the density gradient as an integrated value over the line of sight. in practice, only a random dot pattern in the background of the flow is imaged with a high resolution camera before and during the test. In its simplest form, bos makes use of simple background patterns of the form of a randomly generated dot pattern, an inexpensive strobe light source and a high speed digital camera. in its initial stages of implementation, it is mostly being used as a qualitative visualization method. In this paper, we explore the history and fundamentals of schlieren imaging, the design of a basic schlieren system, advancements in computational schlieren systems, and future applications and analysis techniques implementing schlieren imaging concepts.

Here you can see the original image of a schlieren image from an experiment with a very old camera system. i'm trying to remove these progressive lines using opencv in python but without any luck. There are some free programs you will need for this project. below is a comprehensive list of those used in my video. if you are running my python gui program, you will also need to download the following function file. again, all the files can also be found on my website. Compared to the conventional knife edge schlieren method, bos can visualize large scale flow phenomena and measures the optical flow distortion in form of a digital vector map. In the present study the performance of multi pass cross correlation, iterative horn–schunck and lucas–kanade optical flow algorithms and ftp is assessed using synthetic tests with three types of the displacement fields: uniform, sinusoidal and triangular.
