The BMW kidney grille, also known as the vehicle's front fascia, connects the hood. Its primary functions are ventilation and heat dissipation. Behind the grille lie the cooling radiator and the air‑conditioning condenser. These heat‑dissipating components achieve better cooling with the air flowing in through the grille.
1. The surface curvature of the automobile front grille varies significantly, making it impossible to measure the 3D data of the BMW grille accurately using a coordinate‑measuring machine.
2. Since the vane surfaces are irregular curved surfaces, extremely high scanning accuracy is required for the 3D scanner.

Holon 3D technical engineers proposed a solution based on the problems faced by the enterprise: use the handheld 3D scanner HL‑3DH‑3M to quickly scan and acquire 3D data of the "BMW grille", convert the point‑cloud data into triangular mesh surface data using reverse‑engineering software, and leverage 3D inspection software to rapidly perform a difference analysis between the manufactured "BMW grille" and the original data.
