摘要： A device and method for estimating the elevation angle of one or more objects surrounding a user terminal, include a light-collecting lens arrangement that collects sky scene light from a wide angle, an eyepiece lens arrangement that collimates the sky scene light collected by the light-collecting lens arrangement, and an elevation limit marking that is superimposed over the sky scene light. The elevation limit marking defines an elevation angle above a horizon of the earth that all the one or more objects in a field of view of the device must remain below so that the user terminal has an unobstructed view of the sky in all azimuthal directions.

摘要： A system and a method for estimating the elevation angle of one or more objects surrounding a user terminal include a camera device for capturing an image of the sky and a display device for displaying the image of the sky captured by the camera device. One of the camera device and the display device generates an elevation limit marking in the image of the sky displayed by the display device. The elevation limit marking in the image of the sky defines an elevation angle above a horizon of the earth that all the one or more objects in a field of view of the camera device must remain below so that the user terminal has an unobstructed view of the sky in all azimuthal directions.
