Acquisition Frame Rate (Stereo ace)#

The Acquisition Frame Rate feature available on Stereo ace cameras allows you to set an upper limit for the camera's frame rate.

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。

For example, setting an acquisition frame rate of 5 frames per second (fps) has the following effects:

• If the other factors limiting the frame rate allow a frame rate of more than 5 fps, the frame rate will be kept at a constant frame rate of 5 fps.
• If the other factors limiting the frame rate only allow a frame rate of less than 5 fps, the frame rate won't be affected by the Acquisition Frame Rate feature.

Other limiting factors can be the camera or the projector. If you notice that the desired frame rate can't be reached, get the value BslFrameRateLimitingFactor parameter to determine the reason for the lower than expected frame rate.

设置帧采集速率#

1. 将 AcquisitionFrameRateEnable 参数设置为 true。
2. 将 AcquisitionFrameRate 参数设置为相机帧速率上限（以每秒帧数为单位）。
