step S10: a three-dimensional model of a reference mold is obtained.
It should be noted that the execution subject of the embodiment may be a computing service device with data processing, network communication, and program running functions, such as a mobile phone, a tablet computer, a personal computer, or an electronic device or an aircraft track tracking device capable of implementing the above functions. The present embodiment and the following embodiments will be described below by taking the aircraft trajectory tracking device as an example.
It can be understood that the reference mold refers to a mold which is pre-manufactured according to the commodity required to be produced by a merchant and is the same as the commodity in the actual production manufacturing process;
