How to use

Sample function:

#include <wvr/wvr_marker.h>

if (WVR_StartMarker() == WVR_Success) {
    //
    // start marker observer
    if (WVR_StartMarkerObserver(WVR_MarkerObserverTarget_Aruco) == WVR_Success) {
        // Start Aruco marker observer related resources success

        uint32_t count = 0;
        int result = WVR_GetArucoMarkers(0, &count, WVR_PoseOriginModel_OriginOnGround, nullptr);

        if (result==0 & count!=0) {
            std::vector<WVR_ArucoMarker> markers(count);
            int ret = WVR_GetArucoMarkers(count, &count, WVR_PoseOriginModel_OriginOnGround, markers.data());
            if (ret != WVR_Success) {
                LOGE("%s(%d) WVR_GetArucoMarkers failed ret=(%d)", __FUNCTION__, __LINE__, ret);
                return;
            }
            for (int i = 0 ; i < count ; i ++) {
                // get the Aruco markers

                // collect createInfo and create trackable marker
                WVR_TrackableMarkerCreateInfo info = {markers[i].uuid, "test name"};
                WVR_CreateTrackableMarker(&info);

                // Start trackable marker tracking
                WVR_StartTrackableMarkerTracking(markers[i]);

                // Stop trackable marker tracking
                WVR_StartTrackableMarkerTracking(markers[i]);

                // destroy trackable marker with its uuid
                WVR_DestroyTrackableMarker(markers[i]);
            }
        }

        // release Aruco marker observer related resources success
        if (WVR_StopMarkerObserver(WVR_MarkerObserverTarget_Aruco) == WVR_Success) {

        }
    }

    WVR_StopMarker();
} else {
    // start marker failed!
