1. A method for providing a visual content, adapted to a host, comprising:
providing a reference object at a first location, wherein the reference object provided at the first location is used to remotely aim at a first point with a first distance and accordingly determining a first reference line related to the first point and displaying the first reference line, wherein the first point is associated with an external camera, wherein the reference object is a virtual object acting as a visual aid and is moved in response to a movement of the host so as to aim at the first point by moving the host;
instructing to move the host from the first location to another location;
obtaining an instantaneous reference line related to the first point during a movement of the host;
in response to determining that an angle between the first reference line and the instantaneous reference line is less than an angle threshold, instructing to move farther from the first location;
in response to determining that the angle between the first reference line and the instantaneous reference line is not less than the angle threshold, instructing that a current location is suitable to be regarded as a second location
providing the reference object at the second location, wherein the reference object provided at the second location is used to remotely aim at the first point with a second distance and accordingly determining a second reference line related to the first point and displaying the second reference line;
determining a camera position of the external camera based on the first reference line and the second reference line;
obtaining a specific image captured by the external camera; and
generating a specific visual content via combining the specific image with a virtual scene based on the camera position.
