Beschreibung
Zusammenfassung:	The utility model discloses an electric arc additive manufacturing tungsten needle position detection and correction device which comprises a tungsten needle assembly, an image shooting unit, a tungsten needle correction assembly and a calculation unit, the tungsten needle correction assembly is connected with the tungsten needle assembly and the calculation unit, the image shooting unit is connected with the calculation unit, the image shooting unit shoots the tungsten needle assembly, and the tungsten needle assembly is connected with the calculation unit. The calculation unit calculates initial position pixel coordinates P (X0, Y0) according to images shot by the image shooting unit, image recognition and position calculation are carried out on tungsten needle real-time image data, current tungsten needle tip position pixel coordinate data are obtained, tungsten needle position deviation P (X, Y) is calculated, and the tungsten needle correction assembly corrects the tungsten needle assembly according to t
