]Tracker is a free video analysis and modeling tool built on the Open Source Physics (OSP) Java framework. It is designed to be used in physics education.
Students can see how well a model matches the real world by putting simple dynamical models right on top of videos. Tracker can also be used to look at interference patterns and spectra. Tracker video modeling is a powerful way to combine videos with computer modeling. The tracker includes a Java JRE runtime and Xuggle video engine.
The Xuggle video engine is used by the application to load the video file and analyse the image details. To do intelligent video analysis, you need to figure out which frames from the movie you want to look at and where the object you want to track is. If you want accurate results, you need to calibrate the scale of the video by telling it how long an object is. Since the app is mostly used for physics experiments, it is best to record the experiment with objects whose sizes are known. This programme has to use more than one marker to figure out where the object is in the keyframes.
For example, you can use the Line Profile option to measure how bright an image area is or the Point Mass option to describe how an object, like a ball or car, moves. The analysis results are shown right away in the plot view that is set up for each track. When a new marker is added or its position is changed, the plot is automatically updated so that the information is correct. If you need to figure out the exact coordinates, you can use the Data Tool to get more measurements and statistics. Here, you can find the highest, lowest, and average numbers with just a few clicks.
Tracker Video Analysis And Modeling Software For PC Features
- Manual and automated object tracking with position, velocity, and acceleration overlays and data.
- Center of mass tracks.
- Interactive graphical vectors and vector sums.
- RGB line profiles at any angle, time-dependent RGB regions.
- Model Builder creates kinematic and dynamic models of point mass particles and two-body systems.
- External models animate and overlay multi-point data from separate modeling programs such as spreadsheets and Easy Java Simulations.
- Model overlays are automatically synchronized and scaled to the video for direct visual comparison with the real world.
