Abstract: A method of planning a platform lift, in particular a stairlift, at a stair, the platform lift including a rail, a platform, in particular a chair, a drive unit for driving the platform along the rail, wherein the platform is attached to the drive unit. The method includes acquiring 3D stair data of a stair on which the platform lift is to be installed; calculating based on the acquired 3D stair data a path of travel of the rail, and by retrieving manufacturing constraints, in particular from a database, calculating a feasible path of travel under consideration of the retrieved manufacturing constraints.

Abstract: A method of planning a platform lift. The platform lift includes a rail, platform, chair, and a drive unit attached to the platform to drive the platform along the rail. The method includes acquiring 3D-data of a stair on which the platform lift is to be installed utilizing an augmented reality device. Calculating a travel path of the rail is based on acquired 3D-data and predetermined clearance information. Visualizing part or all of the platform lift is based on the calculated path of travel via the augmented reality device. Acquiring the 3D-data includes observing the stair with the augmented reality device; marking several locations and confirming the locations via a user input; extracting surface information via a computer based analysis of the markings and optical information taken by the augmented reality device. Based on the optical information and predetermined clearance information the path of travel is calculated.
