使用Onvif协议控制预置位

预置位在安防领域有较为普遍的应用，可以进行很多既定位置的跳转，很方便

之前我们说过如何用Onvif协议进行设备的发现，探测，以及云台控制等，今天我们来说一下如何使用Onvif进行预置位的操作

流程

获取设备能力Capabilities

获取设备的能力，并且可以获取到Media和PTZ的URI，使用这两个URL可以进行流和预置位操作，这里如果PTZ URI获取不到意味着这个设备无法支持预置位控制

_tds__GetCapabilities* capabilities = soap_new__tds__GetCapabilities(proxyDevice, -1); tt__CapabilityCategory* category = new tt__CapabilityCategory; capabilities->Category = category; *(capabilities->Category) = tt__CapabilityCategory__All; _tds__GetCapabilitiesResponse* response = soap_new__tds__GetCapabilitiesResponse(proxyDevice, -1); if (SOAP_OK == proxyDevice->GetCapabilities(capabilities, response)) { if (response->Capabilities) { //Media URI: response->Capabilities->Media->XAddr; //PTZ URI: response->Capabilities->PTZ->XAddr; } }

获取Media Profile

_trt__GetProfiles* getProfiles = soap_new__trt__GetProfiles(proxyMedia, -1); _trt__GetProfilesResponse* response = soap_new__trt__GetProfilesResponse(proxyMedia, -1); if (SOAP_OK == proxyMedia->GetProfiles(getProfiles, response)) { int size = response->__sizeProfiles; for (int i = 0; i < size; ++i) { if (response->Profiles[i]) { //Media Profile Token: response->Profiles[i]->token; //一般设备包含多个Profile Token，包含主码流、子码流、第三码流 } } }

预置位控制

bool result = false; PTZBindingProxy* ptzProxy = new PTZBindingProxy; ptzProxy->soap_endpoint = ptzUrl.c_str(); if (!security(ptzProxy, username, password)) { delete ptzProxy; return result; } char presetToken[8]; itoa(index, presetToken, 10); if (command == PRESET_GOTO) { _tptz__GotoPreset* preset = soap_new__tptz__GotoPreset(ptzProxy, -1); _tptz__GotoPresetResponse* response = soap_new__tptz__GotoPresetResponse(ptzProxy, -1); preset->ProfileToken = const_cast(profile.c_str()); preset->PresetToken = presetToken; if (SOAP_OK == ptzProxy->GotoPreset(preset, response)) result = true; if (response) soap_delete__tptz__GotoPresetResponse(ptzProxy, response); if (preset) soap_delete__tptz__GotoPreset(ptzProxy, preset); } else if (command == PRESET_SET) { _tptz__SetPreset* preset = soap_new__tptz__SetPreset(ptzProxy, -1); _tptz__SetPresetResponse* response = soap_new__tptz__SetPresetResponse(ptzProxy, -1); preset->ProfileToken = const_cast(profile.c_str()); preset->PresetToken = presetToken; if (SOAP_OK == ptzProxy->SetPreset(preset, response)) result = true; if (response) soap_delete__tptz__SetPresetResponse(ptzProxy, response); if (preset) soap_delete__tptz__SetPreset(ptzProxy, preset); } else if (command == PRESET_REMOVE) { _tptz__RemovePreset* preset = soap_new__tptz__RemovePreset(ptzProxy, -1); _tptz__RemovePresetResponse* response = soap_new__tptz__RemovePresetResponse(ptzProxy, -1); preset->ProfileToken = const_cast(profile.c_str()); preset->PresetToken = presetToken; if (SOAP_OK == ptzProxy->RemovePreset(preset, response)) result = true; if (response) soap_delete__tptz__RemovePresetResponse(ptzProxy, response); if (preset) soap_delete__tptz__RemovePreset(ptzProxy, preset); } delete ptzProxy; return result;
