The invention discloses a 3D projection scanning test equipment, comprising a frame, a reference measurement platform, an X-axis mechanism, two parallel Y-axis mechanisms, a Z-axis mechanism and a 3D scanner, a reference measurement platform, a reference measurement platform and a Y-axis mechanism Both are set on the frame, the X-axis mechanism is slidingly set on two parallel Y-axis mechanisms, the Z-axis mechanism is slidingly set on the X-axis mechanism, and the 3D scanner is set on the Z-axis mechanism. The 3D scanner includes a 3D scanning system and an industrial vision module. And the screw rod, the screw rod is connected to the output end of the servo motor of the Z-axis mechanism, the 3D scanning system is connected to the screw rod, and the 3D scanning system and the industrial vision module correspond to the benchmark measurement platform. Place the required product on the reference measurement platform, start the equipment to make the X-axis mechanism, Y-axis mechanism and Z-axis mechanism linkage, the 3D scanning system and industrial vision module on the Z-axis mechanism will measure the product, and the measured data will be fed back to The control system performs the export at the end.
