Measurement device for traction pin of semi-trailer and method for measuring traction pin using same

A measurement device for a traction pin of a semi-trailer, comprising:

• a first laser scanner, a second laser scanner, and an estimation module, wherein the first laser scanner is installed at a front of a driving direction of the semi-trailer and has a scanning surface parallel to the driving direction of the semi-trailer,
• wherein the second laser scanner is installed at a side of the driving direction of the semi-trailer, and has a scanning surface perpendicular to the driving direction of the semi-trailer,
• wherein the first laser scanner is disposed at a first predetermined height from a ground surface, and the first predetermined height is greater than a maximum allowed height of the semi-trailer,
• wherein the second laser scanner is disposed at a second predetermined height from the ground surface, and the second predetermined height is less than the maximum allowed height, so that the second laser scanner is positioned to detect the traction pin of the semi-trailer;
• and
• wherein the estimation module is electrically connected with the first laser scanner and the second laser scanner.
