Sažetak
In this study the accuracy of 3D reconstruction systems using different camera setup in horizontal or vertical direction (plane) was investigated. Since it is critical that the object being filmed has to be visible by at least two cameras one is trying to keep cameras as parallel as possi-ble to increase a common field of view. Also camera posi-tioned perpendicular to the area of interest assures better resolution in horizontal and vertical direction (X-axis and Y-axis). On the other hand the depth resolution (Z-axis) suffers when cameras optical axes do not converge enough. Theoretically and also shown in practice angle of intersec-tion from 60° to 120° is equally reliable. The convergent vertical camera set-up (one camera positioned above the other) is expected to encompass both requirements: depth of resolution and satisfactory large common field of view.
