Using Basler pylon to Check the Maximum Allowed Frame Rate
You can use the Basler pylon API to read the current value of the Resulting Frame Rate Abs
parameter from within your application software using the Basler pylon API. The following code
snippet illustrates using the API to get the parameter value:
// Get the resulting frame rate
double resultingFps = Camera.ResultingFrameRateAbs.GetValue();
The Resulting Frame Rate Abs parameter takes all camera settings that can influence the frame
rate into account and indicates the maximum allowed frame rate given the current settings.
You can also use the Basler pylon Viewer application to easily read the parameter.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 19.
Using Direct Register Access to Check the Maximum Allowed Rate
When using direct register access, you work with the "resulting frame period" rather than the frame
acquisition rate. Once the resulting frame period is known, the maximum allowed frame acquisition
rate can be determined by:
To determine the resulting frame period:
Check the value of the Resulting Frame Period Raw register.
The Resulting Frame Period Raw register takes all of camera settings that can influence the frame
period into account and indicates the minimum allowed frame period given the current settings.
A value in a raw register is simply an integer value with no units. To determine what the actual frame
period will be, you must multiply the value in the raw register by the camera’s time base. The time
base on ace cameras is 1 µs.
For example, if you read the Resulting Frame Period Raw register and find that its value is 10000,
the resulting frame period would be 10000 µs (10000 x 1 µs = 10000 µs).
For more information about direct register access, see Section 3.2 on page 21.
