Ok,there may be some mistake. Actually the way I get the transfrom matrix is : convert the coordinate in matadata.xml to longtitude and latitude, and then use this wgs84 position convert to ECEF position and the transform beween them with I used as the transform matrix, and the result matrix is same as the result of Cesium.Transforms.eastNorthUpToFixedFrame (this is why said the ENU matrix I used by mistaken). Is ok?
