Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0018] see figure 1 , first set a 3*3 nine-point map on the printing table, or print a 4x4 or more positive coordinate multi-point map according to needs. At this time, use camera 1 to take pictures and read the photo data, and then according to the nine-point Pixels, the coordinates of camera 1 and print head 2 are calibrated. After the print head 2 is adjusted, the deviation will not be large, so there is no need to consider the problem of too far de...

The invention relates to a 3D printing secondary printing positioning method using a camera for positioning. The 3D printing secondary printing positioning method includes the steps that the camera is used for recording the original position of a printed objected firstly printed by a printing head; other treatment is conducted on the printed object, and the treated printed object is placed back to an original printing table top; the camera is used for recording the current position of the printed object again; current position information of the printed object is calculated and compared with the original position information, and the horizontal displacement and rotational displacement are calculated; and the printing head conducts secondary printing according to the calculation result. The camera is used for recording the position of the originally printed object and the position of the secondarily printed object, calculating fitting is conducted on the position of the secondarily printed object and the position of the originally printed object, then printing is conducted, and thus the position of the secondarily printed object and the position of the originally printed object have no relative displacement.
Description
technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing secondary printing positioning method using a camera for positioning. Background technique [0002] The current 3D printing, one-time molding, when secondary processing is required, such as modification or addition, when the original printed object is printed for the second time, there is a printing deviation caused by the position of the original printed object being moved, so it is difficult in the prior art Realize secondary printing. Contents of the invention [0003] In view of the above problems, it is necessary to propose a 3D printing secondary printing positioning method using a camera to locate the secondary printing object and the original printing object accurately. [0004] A 3D printing secondary printing positioning method utilizing camera positioning, comprising the following steps: [0005] Use the camera to record the original position of t...
