A method for measuring the distance of an object from a measuring device is disclosed, said method comprising the following steps:

Method for measuring the distance of an object

A method of reconstructing successive scans of bar codes having a plurality of dark elements separated from light elements, comprising the steps of: performing a first scan of the bar code thereby determining the position and the width of the elements in the first scan with respect to an absolute reference position; calculating the position which the elements in the first scan will take with respect to the absolute reference position in a subsequent scan; making a second scan of the bar code thereby determining the position and the width of the elements in the second scan with respect to the absolute reference position; carrying out a correspondence search step for finding at least one reference element for the first scan and one reference element for the second scan, which have substantially the same position with respect to the absolute reference position and substantially the same width; and combining the elements in the first scan with the elements in the second scan, generating a reconstructed scan.

Method of reconstructing successive scans of a bar code

The reading method includes the step of successively performing a first and at least a second scan of an optical code along a first and, respectively, second scanning line parallel to each other. More specifically, the first and second scan of the optical code are performed by generating a first and a second laser light ray movable respectively in a first and second scanning plane distinct from and intersecting each other.
