The embodiment of the invention relates to a method and device for
processing a target object and a storage medium. The method comprises the steps that first sampling data about multiple sampling moments of the target object and second sampling data about multiple sampling moments of a first motor and a second motor are acquired; determining a first real-time rolling
diameter of the target object on the first roller and a second real-time rolling
diameter of the target object on the second roller according to the first sampling data and the second sampling data; and according to the first real-time rolling
diameter and the second real-time rolling diameter, the torque and / or the angular speed of the first motor and / or the second motor are / is adjusted, so that the tension stability and / or the linear speed stability of the target object are / is maintained. According to the technical scheme, the tension stability and / or the linear speed stability of the target object can be maintained, so that the spray
dyeing effect is improved.
