Coordinate system for flat rectangular surfaces

Hi all,


i would like to seasonally measure distances and areas inside a rectangle (200 cm x 150 cm) fixed with permanent marks in a vertical wall. The idea was to gain pictures and transfer them to ArcGIS desktop 10.2.

So i thought to create a new projected coordinate system with the reference scale based on the dimension of the rectangle side and the coordinates departing from the permanent vertices [i.e. vertices coordinates:  upper left (0 ; 150), upper right (200 ; 150), bottom left (0 ; 0), bottom right (200; 0)].

Platee Caree seems to be appropriate for the projection but i cannot find a solution for the coordinate system, would you be so kind to help me?


Thanks in advance,
