海康 PTZ HTTP控制

    型号: 海康 DS-2DM7274-A

    控制通过HTTP实现,  pan 左右移动 titl 上下移动  zoom 缩放   看主要代码吧.

 

    生成命令:

 switch(iCommand)
 {
 case PTZ_LEFT:
  sprintf(strXMLInfo, "-%d0", iRate);
  break;
 case PTZ_RIGHT:
  sprintf(strXMLInfo, "%d0", iRate);
  break;
 case PTZ_UP:
  sprintf(strXMLInfo, "0%d", iRate);
  break;
 case PTZ_DOWN:
  sprintf(strXMLInfo, "0-%d", iRate);
  break;
 case PTZ_UP_LEFT:
  sprintf(strXMLInfo, "-%d%d", iRate, iRate);
  break;
 case PTZ_UP_RIGHT:
  sprintf(strXMLInfo, "%d%d", iRate, iRate);
  break;
 case PTZ_DOWN_LEFT:
  sprintf(strXMLInfo, "-%d-%d", iRate, iRate);
  break;
 case PTZ_DOWN_RIGHT:
  sprintf(strXMLInfo, "%d-%d", iRate, iRate);
  break;
 case PTZ_ZOOM_IN:
  sprintf(strXMLInfo, "-%d", iRate);
  break;
 case PTZ_ZOOM_OUT:
  sprintf(strXMLInfo, "%d", iRate);
  break;
 case PTZ_FOCUS_FAR:
  sprintf(strCommand, "PUT /PSIA/System/Video/inputs/channels/%d/focus HTTP/1.1", iChannel);
  sprintf(strXMLInfo, "%d", iRate);
  break;
 case PTZ_FOCUS_NEAR:
  sprintf(strCommand, "PUT /PSIA/System/Video/inputs/channels/%d/focus HTTP/1.1", iChannel);
  sprintf(strXMLInfo, "-%d", iRate);
  break;
 case PTZ_IRIS_INC:
  sprintf(strCommand, "PUT /PSIA/System/Video/inputs/channels/%d/iris HTTP/1.1", iChannel);
  sprintf(strXMLInfo, "%d", iRate);
  break;
 case PTZ_IRIS_DEC:
  sprintf(strCommand, "PUT /PSIA/System/Video/inputs/channels/%d/iris HTTP/1.1", iChannel);
  sprintf(strXMLInfo, "-%d", iRate);
  break;
 case PTZ_SAVE_PRESET:
  sprintf(strCommand, "PUT /PSIA/PTZ/channels/%d/presets/%d HTTP/1.1", iChannel, iPresetID);
  memset(szInfo, 0, 512);
  sprintf(szInfo, "%d%s", iPresetID, strPresetName);
  //GB2312ToUTF_8(strXMLInfo, iLen, szInfo, strlen(szInfo));  //有中文需要转为UTF_8
  break;
 case    PTZ_LOAD_PRESET:    
  sprintf(strCommand, "PUT /PSIA/PTZ/channels/%d/presets/%d/goto HTTP/1.1", iChannel, iPresetID);
  break;
 case PTZ_HOME:
  sprintf(strCommand, "PUT /PSIA/Custom/SelfExt/PTZ/channels/%d/homePosition/goto HTTP/1.1", iChannel);
  break;
 case PTZ_GET_PRESET:
  sprintf(strCommand, "GET /PSIA/PTZ/channels/%d/presets HTTP/1.1", iChannel);
  break;
 default:
  break;
 }

 

发送命令:
