All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a cut piece screening method, which is shown in figure 1 and comprises the following steps:
step S11: and selecting one cut piece which is not required to be cut currently from all cut pieces positioned on the target CAD graph to obtain the target cut piece.
Specifically, the present embodiment may provide a target cut-part selection interface for a user in advance, and through the target cut-part selection interface, selection information of a cut part that is input by the user and does not need to be cut on the target CAD drawing may be acquired, and then according to the selection information, a corresponding cut part may be searched from the target CAD drawing, so as to obtain the target cut part.
Of course, in this embodiment, the background system may also automatically identify a cut segment that does not need to be cut from the current target CAD drawing according to the current cutting progress state, so as to obtain the target cut segment.
Step S12: and carrying out area estimation on the target cut piece and the rest cut pieces on the target CAD drawing to obtain the area of each cut piece on the target CAD drawing.
That is, the present embodiment performs area estimation on all the cut pieces on the target CAD drawing, so as to obtain the area of the cut piece corresponding to each cut piece.
Step S13: and screening out cut pieces with the difference value between the area of the cut piece and the area of the cut piece of the target CAD graph being smaller than a preset threshold value from the rest cut pieces on the target CAD graph to obtain the screened cut pieces.
In this embodiment, after the target cut piece and the area of each cut piece on the target CAD drawing are determined, the cut pieces with the difference value smaller than the preset threshold value between the area of the cut piece and the area of the target cut piece are screened from all the other cut pieces on the target CAD drawing except the target cut piece, so as to obtain the screened cut pieces. It is understood that the above difference refers to an absolute value of an area difference between the cut pieces. The specific value of the preset threshold is not necessarily too large, and may be generally 5 area units.
Step S14: and determining the target cut pieces and the screened cut pieces as the cut pieces which do not need to be cut currently to obtain a target cut piece set.
It will be appreciated that after the target panel and the screened panels are determined to be panels that currently do not need to be cut, the subsequent cutting process will not cut those panels.
Therefore, when the cut pieces which do not need to be cut on the target CAD drawing are screened, one cut piece which does not need to be cut at present is selected from the target CAD drawing to serve as the target cut piece, then the area of the cut piece is used as the screening basis, the cut piece similar to the target cut piece is screened from the rest cut pieces on the target CAD drawing, namely, the cut piece with the smaller difference between the area of the cut piece and the area of the cut piece of the target cut piece is screened from the rest cut pieces on the target CAD drawing, therefore, the screening efficiency of the cut pieces can be greatly improved, the subsequent cutting efficiency is favorably improved, and the project schedule is accelerated.

Step S23: the area estimation is performed on the target cut piece and the remaining cut pieces on the target CAD drawing by determining the area of the circumscribed rectangle of each cut piece as the cut piece area of the cut piece.
In this embodiment, since the shapes of the cut pieces themselves on the target CAD drawing are usually irregular, if it is necessary to calculate the actual areas of the cut pieces, a large amount of computing resources and computing time are consumed, while the calculation process of the areas of the circumscribed rectangles of the cut pieces is relatively simple, and only very little computing resources and computing time are needed, so that the area of the circumscribed rectangle of each cut piece is preferentially regarded as the area of the cut piece, and this area estimation method can greatly increase the overall screening speed of the cut piece.
It is understood that, in the present embodiment, the circumscribed rectangle may be replaced by a circumscribed polygon having other shapes such as a circumscribed triangle, a circumscribed pentagon, and the like, or may be replaced by a circumscribed circle.
Step S24: and screening out cut pieces with the difference value between the area of the cut piece and the area of the cut piece of the target CAD graph being smaller than a preset threshold value from the rest cut pieces on the target CAD graph to obtain the screened cut pieces.
Further, before the process of determining the target cut segment and the screened cut segment as the cut segment which does not need to be cut currently, the embodiment of the present invention may further include: the misselected cut pieces in the filtered cut pieces are removed by using the misselected cut piece removing instruction triggered by the user, so that the accuracy of the cut piece filtering result is further improved.

That is, after the above step S321, the status of each panel in the target panel set is the selected status, and the statuses of all the panels on the target CAD drawing except for the target panel set are the unselected statuses.
Step S322: and reading the state information of all cut pieces on the target CAD graph, cutting the cut piece if the read state of any cut piece is a non-selected state, and forbidding cutting the cut piece if the read state of any cut piece is a selected state.
Correspondingly, the embodiment of the invention also discloses a cut piece screening system, which is shown in fig. 4 and comprises:
