中文翻譯
語法爲：pcd_viewer <file_name 1..N> .pcd <options>
選項是：
-bc r，g，b =背景顏色
-fc r，g，b =前景色
-ps X =點大小（1..64）
-opaque X =渲染點雲不透明度（0..1）
-ax n =啓用XYZ軸的屏幕顯示並將其縮放到n
-ax_pos X，Y，Z =如果啓用軸，則在空間中設置其X，Y，Z位置（默認爲0,0,0）
-cam（*）=使用給定的攝像機設置作爲初始視圖
（*）[剪切範圍/焦點/位置/視圖上限/距離/窗口大小/窗口位置]或使用包含相同信息的<filename.cam>。
-multiview 0/1 =啓用/禁用自動多視口渲染（默認禁用）
-normals 0 / X =禁用/啓用每個第X點的曲面法線顯示爲線（默認爲禁用）
-normals_scale X =將正常單位矢量大小調整爲X（默認值爲0.02）
-pc 0 / X =禁用/啓用每個X點的主曲率顯示爲線（默認禁用）
-pc_scale X =將主曲率向量大小調整爲X（默認值爲0.02）
（注意：對於多個.pcd文件，提供多個 - {fc，ps}參數;它們將自動分配給正確的文件）
英文原文
Syntax is: pcd_viewer <file_name 1..N>.pcd <options>
where options are:
-bc r,g,b = background color
-fc r,g,b = foreground color
-ps X = point size (1..64)
-opaque X = rendered point cloud opacity (0..1)
-ax n = enable on-screen display of XYZ axes and scale them to n
-ax_pos X,Y,Z = if axes are enabled, set their X,Y,Z position in space (default 0,0,0)
-cam (*) = use given camera settings as initial view
(*) [Clipping Range / Focal Point / Position / ViewUp / Distance / Window Size / Window Pos] or use a <filename.cam> that contains the same information.
-multiview 0/1 = enable/disable auto-multi viewport rendering (default disabled)
-normals 0/X = disable/enable the display of every Xth point's surface normal as lines (default disabled)
-normals_scale X = resize the normal unit vector size to X (default 0.02)
-pc 0/X = disable/enable the display of every Xth point's principal curvatures as lines (default disabled)
-pc_scale X = resize the principal curvatures vectors size to X (default 0.02)
(Note: for multiple .pcd files, provide multiple -{fc,ps} parameters; they will be automatically assigned to the right file)
