Acquisition Frame Rate#

相机的 Acquisition Frame Rate 功能允许您设置相机帧速率上限。

如果要在自由运行图像采集中以恒定的帧速率操作相机,此功能很有用。

该功能的使用#

运作原理#

如果启用了 Acquisition Frame Rate 功能,相机的最大帧速率受您输入的 Acquisition Frame Rate 参数值的限制。

例如,将帧采集速率设置为 20 帧/秒 (fps) 具有以下效果:

  • 如果另一个限制帧速率的系数允许高于 20 帧/秒的帧速率,帧速率将保持在 20 fps 的恒定值。
  • 如果另一个限制帧速率的系数仅允许帧速率低于 20 fps,则帧速率将不受 Acquisition Frame Rate 功能的限制。

信息

To determine the actual frame rate, use the Resulting Acquisition Frame Rate feature.

设置帧采集速率#

  1. 设置 AcquisitionFrameRateEnable parameter to true (如果可用).
  2. 设置 AcquisitionFrameRate parameter to the desired upper limit for the camera's frame rate in frames per second.
