Do you need to lock the tripod head when DJI UAV takes pictures?

When taking pictures with DJI UAV, the pan/tilt is usually locked to obtain more stable image and video quality. Pan-tilt is a mechanical part on UAV, which is used to stabilize the camera or video camera to reduce the jitter and shaking during flight. By locking the pan/tilt, the position of the camera can be fixed, thus reducing the possibility of image blur and jitter and making the photos clearer and more stable.
