橡皮工具可用于将单个像素或随机形状的区域，甚至是不连续的区域定义为 "不感兴趣 "区域。在绘图工具的下拉菜单中，可通过以下按钮启用橡皮工具
通过以下按钮启用：
点击该按钮后，可以在整个屏幕上进行擦除操作，直到点击下拉菜单中带有划线橡皮擦的按钮退出擦除模式。
信息：
也可以用 Escape 键退出擦除模式。
此外，当添加下一个 ROI 绘图工具时，擦除模式会自动退出。根据后添加的 ROI 工具应用较晚，因此占主导地位的规则，这个后添加的工具可以将刚刚被擦除的区域再次定义为 "感兴趣 "的区域。下一次使用橡皮擦时，就会创建一个可以擦除的新图层。这些橡皮图层不能被选中，因此也不能被删除。
如果使用可用的绘图工具绘制的 ROI 过于杂乱，可以通过将 ROI 转移到相机来评估所得到的区域。所得到的 ROI 区域由摄像机确定、保存、返回并显示在人机界面应用程序中，在人机界面应用程序中可以通过添加或减少附加区域对其进行进一步编辑。
信息：
如果按住鼠标右键，可以再次删除已擦除的像素，但这只适用于活动的擦除层。
The eraser tool can be used to define individual pixels or randomly shaped, even non-contiguous, areas as "not of interest". The eraser is enabled in the dropdown menu for the drawing tools
via the following button:
When clicking the button, it is possible to erase on the whole screen until erase mode is exited by clicking the button with the crossed-out eraser that appears in the drop-down menu when erasing mode is active.
Information:
Erase mode can also be exited with the Escape key.
In addition, erase mode is automatically exited when the next ROI drawing tool is added. According to the rule that ROI tools added later are applied later and therefore dominant, this later-added tool can define areas that have just been erased as "of interest" again. The next time the eraser is used, a new layer is created that can be erased. These eraser layers cannot be selected and can thus not be deleted.
If the ROI drawing becomes too cluttered with the drawing tools available, the resulting area can be evaluated by transferring the ROI to the camera. The resulting ROI area is determined by the camera, saved, returned to and displayed in the HMI application where it can be further edited by adding or subtracting additional areas.
Information:
If the right mouse button is held down, erased pixels can be removed again, but this only applies to the active eraser layer.
