A system for measuring a set of key features (Ws, Hs, Ds) of a rotary milking parlor arrangement, which comprises a rotating platform with a plurality of stalls each of which is configured to house a respective animal during milking, said stalls being separated from one another by delimiting structures (DS1, DS2), the system comprising: a camera configured to register three-dimensional image data (D img3D) of the rotating platform within a field of view, and a control unit configured to process the registered image data (D img3D), wherein the control unit is configured to: receive the image data (D img3D) that has been registered while the rotating platform completes at least one full revolution around its rotation axis; process the image data (D img3D) to derive the set of key features (W S, H S, D S), wherein the set of key features (W S, H S, Ds) comprises at least one of: data describing physical characteristics of at least one piece of fixed equipment (EQ1, EQ2) arranged in at least one of said stalls, a respective width measure (Ws) of each of said stalls, a respective height measure (H S) of the delimiting structures (DS1, DS2) separating said stalls from one another, a respective depth measure (Ds) of each of said stalls and a position (P KR) of a structure arranged on a stationary part of the rotary milking parlor arrangement, which structure is configured to prevent the hind legs of an animal in one of said stalls from reaching outside of a safety zone for said one of said stalls; and wherein the control unit is configured to: store the set of key features (W S, H S, D S) in a data storage which is configured to make the set of key features (Ws, Hs, S D) available for use at a later point in time. a camera configured to register three-dimensional image data (D img3D) of the rotating platform within a field of view, and a control unit configured to process the registered image data (D img3D), wherein the control unit is configured to: receive the image data (D img3D) that has been registered while the rotating platform completes at least one full revolution around its rotation axis; process the image data (D img3D) to derive the set of key features (W S, H S, D S), wherein the set of key features (W S, H S, Ds) comprises at least one of: data describing physical characteristics of at least one piece of fixed equipment (EQ1, EQ2) arranged in at least one of said stalls, a respective width measure (Ws) of each of said stalls, a respective height measure (H S) of the delimiting structures (DS1, DS2) separating said stalls from one another, a respective depth measure (Ds) of each of said stalls and a position (P KR) of a structure arranged on a stationary part of the rotary milking parlor arrangement, which structure is configured to prevent the hind legs of an animal in one of said stalls from reaching outside of a safety zone for said one of said stalls; and wherein the control unit is configured to: store the set of key features (W S, H S, D S) in a data storage which is configured to make the set of key features (Ws, Hs, S D) available for use at a later point in time. receive the image data (D img3D) that has been registered while the rotating platform completes at least one full revolution around its rotation axis;
