Abstract

Although zoom lens has been widely accepted in vision system, the use of zoom lens was not general in close range photogrammetry from the view point of instability by zooming. However, with the spread of consumer grade digital cameras with integrated zoom lens, in particular long range such as ×35, digital close range photogrammetry using the camera is enormously expected in various application fields. There is a large body of literature on calibration of zoom lens. However, there is still problem for effective digital photogrammetry using the camera. The problem is practical calibration model for zoom lens, in particular correction of misalignment which is caused by zoom setting. In order to resolve instability of zoom lens, and practical use of digital close range photogrammetry using zoom lens, a new calibration model is proposed in this paper based on correction of zoom lens misalignment. Furthermore, in order to evaluate the proposed calibration model for zoom lens, calibration tests were conducted using 5 kinds of consumer grade digital camera with integrated zoom lens (×3~5), 3 kinds of long range consumer grade digital camera (×12~30) and digital SLR camera with zoom lens (×11).
