Image ROI#
ROI 是 Region of Interest(即兴趣区的英文首字母缩写,以前为 AOI = 兴趣区)。
如果指定了图像 ROI,则相机将仅传输该区域内的像素数据。在大多数相机上,这会大大提高相机的最大帧速率。
图像 ROI 设置独立于自动功能 ROI 设置。
该功能的使用#
更改 Image ROI 的位置和大小#
启用出厂设置后,相机将设置为默认分辨率。但是,您可以根据需要更改位置和大小。
要更改图像 ROI 的位置和大小,请执行以下操作:
- 确保相机空闲,即未在捕获图像。
- If you are using an ace Classic/U/L camera, set the
CenterX
andCenterY
parameters tofalse
. -
使用以下参数指定图像 ROI 的大小:
Width
Height
-
使用以下参数指定图像 ROI 的位置:
OffsetX
OffsetY
图像 ROI 的原点位于传感器阵列的左上角(第 0 列、第 0 行)。
示例:假设您指定了以下设置:
Width
= 16Height
= 10OffsetX
= 2OffsetY
= 6
这将创建以下图像 ROI:
信息
- 在大多数相机上,减小 Image ROI 的大小(尤其是高度)会显著提高相机的最大帧速率。
- 如果启用了 Binning 功能,图像 ROI 设置是指经过像素合并的行和列,而不是传感器中的物理线路。
- 在 racer 2 cameras, the
OffsetY
parameter is not available. - 在 boA5120-230cc, boA5120-230cm cameras, the
OffsetY
parameter is not available. The position of the image ROI is always centered in vertical direction. - 在 boA13440-17cm cameras, the position of the image ROI is always centered in horizontal and vertical direction. When you change the width of the image ROI, the
OffsetX
parameter value automatically adapts and the image ROI is centered horizontally. When you change the height of the image ROI, theOffsetY
parameter value automatically adapts and the image ROI is centered vertically.
Both theOffsetX
andOffsetY
parameters are read-only.
指导准则#
指定图像 ROI 时,请遵循以下准则:
指导准则 | 示例 |
---|---|
OffsetX + Width ≤ WidthMax | Camera with a 1920 x 1080 pixel sensor:OffsetX + Width ≤ 1920 |
OffsetY + Height ≤ HeightMax | Camera with a 1920 x 1080 pixel sensor:OffsetY + Height ≤ 1080 |
即: WidthMax
and HeightMax
parameter values adapt to the current settings for Binning, Decimation, or Scaling (if available).
