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, "<PTZData><pan>-%d</pan><tilt>0</tilt></PTZData>", iRate);

break;

case PTZ_RIGHT:

sprintf(strXMLInfo, "<PTZData><pan>%d</pan><tilt>0</tilt></PTZData>", iRate);

break;

case PTZ_UP:

sprintf(strXMLInfo, "<PTZData><pan>0</pan><tilt>%d</tilt></PTZData>", iRate);

break;

case PTZ_DOWN:

sprintf(strXMLInfo, "<PTZData><pan>0</pan><tilt>-%d</tilt></PTZData>", iRate);

break;

case PTZ_UP_LEFT:

sprintf(strXMLInfo, "<PTZData><pan>-%d</pan><tilt>%d</tilt></PTZData>", iRate, iRate);

break;

case PTZ_UP_RIGHT:

sprintf(strXMLInfo, "<PTZData><pan>%d</pan><tilt>%d</tilt></PTZData>", iRate, iRate);

break;

case PTZ_DOWN_LEFT:

sprintf(strXMLInfo, "<PTZData><pan>-%d</pan><tilt>-%d</tilt></PTZData>", iRate, iRate);

break;

case PTZ_DOWN_RIGHT:

sprintf(strXMLInfo, "<PTZData><pan>%d</pan><tilt>-%d</tilt></PTZData>", iRate, iRate);

break;

case PTZ_ZOOM_IN:

sprintf(strXMLInfo, "<PTZData><zoom>-%d</zoom></PTZData>", iRate);

break;

case PTZ_ZOOM_OUT:

sprintf(strXMLInfo, "<PTZData><zoom>%d</zoom></PTZData>", iRate);

break;

case PTZ_FOCUS_FAR:

sprintf(strCommand, "PUT /PSIA/System/Video/inputs/channels/%d/focus HTTP/1.1", iChannel);

sprintf(strXMLInfo, "<FocusData><focus>%d</focus></FocusData>", iRate);

break;

case PTZ_FOCUS_NEAR:

sprintf(strCommand, "PUT /PSIA/System/Video/inputs/channels/%d/focus HTTP/1.1", iChannel);

sprintf(strXMLInfo, "<FocusData><focus>-%d</focus></FocusData>", iRate);

break;

case PTZ_IRIS_INC:

sprintf(strCommand, "PUT /PSIA/System/Video/inputs/channels/%d/iris HTTP/1.1", iChannel);

sprintf(strXMLInfo, "<IrisData><iris>%d</iris></IrisData>", iRate);

break;

case PTZ_IRIS_DEC:

sprintf(strCommand, "PUT /PSIA/System/Video/inputs/channels/%d/iris HTTP/1.1", iChannel);

sprintf(strXMLInfo, "<IrisData><iris>-%d</iris></IrisData>", 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, "<PTZPreset><id>%d</id><presetName>%s</presetName></PTZPreset>", 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;

}
