Question

The camera axis of an aerial camera is defined as

• A. the line joining the optical centres of the objective and eyepiece lens.
• B. the perpendicular line between the photographic centre and optical centre of the objective lens.
• C. the line passing through the centre of the camera lens and perpendicular to the camera plane and the photo plane.
• D. the line perpendicular to the plumb line.

Hint:

The camera axis is defined as the perpendicular line between the photographic center and the optical center of the objective lens, which is key for correct camera alignment in aerial photography.

Answer 1

The Correct Option is B

The camera axis of an aerial camera is a critical concept in photogrammetry. It is the line that represents the direction of the camera during the image capture process. The camera axis is defined as the perpendicular line between the photographic center and the optical center of the objective lens. This line is important for proper alignment in aerial photography and image processing. Step 1: Analyzing the options. - Option (A) is incorrect because the optical centers of the objective and eyepiece lens are not involved in defining the camera axis. The eyepiece lens is not directly related to the camera axis. - Option (B) is correct because it accurately defines the camera axis, which is the perpendicular line between the photographic center and the optical center of the objective lens. - Option (C) is incorrect because the camera axis does not necessarily pass through the center of the lens and is not directly related to the plane of the photo. - Option (D) is incorrect because the plumb line is a different concept, not related to the camera axis. Thus, the correct answer is (B).
