Fork-Lift Truck
First Claim
1. A fork-lift truck comprising;
- a load carrier;
an optical detector having a first field of view and providing an output, wherein the optical detector is movable together with the load carrier;
an optical analysing unit analyzing the output from said optical detector to identify a first three-dimensional object, said first three-dimensional object being the load carrier, and a second three-dimensional object based on the output from the optical detector, and to determine the three-dimensional position of the identified load carrier relative to the identified second three-dimensional object.

Abstract
A fork-lift truck 1, 1′ including a load carrier 2, an optical detector 3, 3′ having a first field of view and arranged to provide an output, wherein the optical detector 3, 3′ is movable together with the load carrier 2, an optical analysing unit 4, 4′ arranged to analyse the output from said optical detector 3, 3′. The optical analysing unit 4, 4′ is arranged to analyse the output from the optical detector 3, 3′ so as to identify a first three-dimensional object, said first three-dimensional object being the load carrier 2, and a second three-dimensional object based on the output from the optical detector 3, 3′, and to determine the three-dimensional position of the identified load carrier 2 relative to the identified second three-dimensional object. Further a method for operating a fork-lift truck, a method for modifying a fork-lift truck and a computer program product.

13. A method of operating a fork-lift truck, said fork-lift truck including an optical detector having a first field of view, said method comprising the steps of:
-
obtaining an output from the optical detector; identifying a first three-dimensional object in said field of view of the optical detector and determining its position, said first three-dimensional object being a load carrier of the fork-lift truck, based on the output from the optical detector; identifying a second three-dimensional object in said field of view of the optical detector and determining its position based on the output from the optical detector; and determining a three-dimensional relative position of the identified second three-dimensional object in relation to the position of the identified load carrier based on the determined position of the load carrier and the determined position of the second three-dimensional object. - View Dependent Claims (14, 15, 16, 17, 18, 20)
