蒙版参数

警告
本文介绍的功能在 Community SDK 版本中不可用。
您应该升级到 Engineering / Sim SDK版本才能使用它。

Mask is landcover data based on which natural features of the terrain are generated: details, grass, trees, etc.蒙版 是生成地形自然特征的土地覆盖数据:细节、草地、树木等。

Masks are added the same way as Elevation and Imagery, both online and offline data sources can be used. The data contained in a mask source can be filtered to fine-tune the use of the mask for a specific purpose.蒙版的添加方式与 高程和照片 相同,在线和离线数据源都可以使用。蒙版源中包含的数据可以过滤,以针对特定目的微调蒙版的使用。

An example of creating a Mask is given here.这里 给出了创建 蒙版 的示例。

Filters
过滤器#

Filters select specific data from the data source for each type of the generated landcover object. There are three types of filters:过滤器为生成的地形覆盖对象的每种类型从数据源中选择特定的数据。过滤器有三种类型:

Indexed

Select a particular color index from the list of available ones in the source raster image. You can also specify the color range by indices (from color to color).从列表中选择一个特定的颜色指数可用的光栅图像的来源。您还可以指定颜色范围指数(从颜色的颜色)。

Single Channel

Select a channel of the source raster image.选择一个频道的光栅图像来源。

Color

Set a particular color taken from the source raster image and adjust the Range for it, thus defining the suitable deviation from the specified color within the range [0, 255].设置从源光栅图像中提取的特定颜色,并为其调整Range,从而在[0, 255]范围内定义与指定颜色的适当偏差。

Click on the color to open the color settings:点击打开颜色设置:

Select the color from available, use HSV or RGBA values, or click Pick Screen Color to select the color from the image in the Preview panel:从可用的颜色中选择颜色,使用HSV或RGBA值,或单击Pick Screen ColorPreview面板中的图像中选择颜色:

Range — threshold value for the color that defines a range of colors to be used for the filter. 0 means that only the selected color is used as mask, increasing the Range value makes the filter include the specified number of neighboring colors.Range 是颜色的阈值,它定义了用于过滤器的颜色范围。0意味着只有选定的颜色作为面具,增加Range值使过滤器包括指定数量的邻近的颜色。

Copy filters
Copy Filters Button

Opens the window to copy all filters from the current source to the selected sources:打开窗口,从当前源复制所有筛选器到所选源:

Copy Filters Window

If you change anything in filters that you have already copied, and want these changes to be applied to other sources, you need to copy the filters once again. All filters of the selected sources will be replaced with the filters of the current source.如果你改变任何过滤器,你已经复制,并希望这些变化应用到其他来源,你需要再次复制过滤器。所有过滤器的选择的来源将会替换为电流源的过滤器。

Delete all filters
