Multi-camera unit structure and device
A multi-camera unit structure includes a first camera unit, a second camera unit, a third camera unit and a calibrated-image generation unit. The second camera unit is distant from the first camera unit with a first distance in a first direction. With taking the first camera unit as an imaging reference, the first and the second camera units obtain a first DOF image of a target object. The third camera unit is distant from the first camera unit with a second distance in a second direction. The first and second directions define an included angle. With taking the first camera unit as an imaging reference, the third and the first camera units obtain a second DOF image of the target object. The calibrated-image generation unit obtains a calibrated DOF image according to the first and the second DOF images.
