Motion Analysis
Advanced analysis tools for quantifying motion in a recorded video
In addition to high-speed recording, the VW-9000 Series also has software available to perform analysis on the videos. It can remember specified points (areas) in the video and track them to see how much change has occurred between each frame. Other functions include velocity, acceleration, distance (displacement), angle and blur width calculations.
Trail Display Tool
Improved tracking accuracy
The VW-9000 is capable of tracking objects in a recorded video based on the principle of pattern matching. After analyzing user-specified areas on the screen before and after each frame, coordinate points for the targeted areas are saved to memory. From these coordinates and their time information, velocity and distance (displacement) can be analyzed. By improving the accuracy of the software, analysis of the changes can be tracked in real-time. Even previously difficult-to-track movements, such as those of a revolving object, can be easily tracked.
Graphing and Quantifying Images
After tracking an object, the results are displayed as a graph. The VW-9000 allows you to perform quantitative evaluation of the amount of movement, frequency, and changes in movement.
In addition to viewing images that have been recorded at high-speeds, analyzing the behavior in the images leads to the identification of causal relationships. By quantifying changes in an image, verifiable steps can be taken to create and evaluate solutions.
