The Stabilization Evaluation Equipment (STEVE) is designed for qualitative analysis of image stabilizing systems under reproducible, realistic conditions.
STEVE-2D is calibrated to provide the best performance at the most significant frequency/amplitude combination of the human tremor of 4 Hz and 0.2 degrees. The whole range of available frequencies and angles of the movement corresponds to the properties of the typical tremor. For the initial setup, the mounting stage allows you to adjust the camera position.
The movement parameters of the two axes can be controlled separately. Moving about a single axis (yaw or pitch) is possible, as well as simultaneous operation in a parallel or antiparallel way. Both, simple sine shaped motion and individual curves (e.g., to simulate a real handshake) can be measured and logged.
To determine the influence of the handshake, it is necessary to combine STEVE with a test chart. Image Engineering recommends our AF-Box with TE261.
