It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted so as to not unnecessarily obscure the present invention.
In the embodiment, two digital twin models are taken as an example, and the automatic adsorption method for the three-dimensional scene model based on digital twin is described in detail.
Example 1
An automatic adsorption method of a three-dimensional scene model based on digital twinning specifically comprises the following steps:
s1, importing a model A and a model B into a three-dimensional scene, and respectively obtaining parameter information of model bounding boxes of the model A and the model B, wherein the model bounding boxes are of cube structures, and refer to the attached figure 1;
s2, clicking and dragging the model B, and calling the following method to control the model B to desorb the model A by the system in response to the movement control of the model B so as to realize automatic adsorption between the model B and the model A;
the method comprises the following steps:
s21, converting the bounding box cubes of the two models into two-dimensional projection views of three planes, namely an XY plane (top view), a YZ plane (left view) and an XZ plane (front view), through three-view projection, wherein all the projection views are rectangular, and then three-view two-dimensional projection of a bounding box of a model A and three-view two-dimensional projection of a bounding box of a model B are obtained;
s22, taking a top view of an XY plane as an example, top view projection vertexes A1, A2, A3 and A4 of a model A bounding box and top view projection vertexes B1, B2, B3 and B4 of a model B bounding box can be respectively extracted through top view projection of the XY plane, and X-axis coordinates and Y-axis coordinates of the above points are respectively recorded and are expressed by X and Y;
s23, respectively calculating the slope kA of the side A1A2 connected with the top view projection vertexes A1 and A2 of the model A bounding box and the slope kB of the side B1B2 connected with the top view projection vertexes B1 and B2 of the model B bounding box in a two-point one-line mode, wherein a specific calculation formula is slope k= (y 2-y 1)/(x 2-x 1), and calculating results are respectively marked as kA and kB;
s24, judging whether the two values of kA and kB are equal, if not, indicating that the two models have no parallel surfaces, and if not, judging again after rotating the models; if equal, it is indicated that model A and model B have parallel surfaces, and the adjacent surfaces of the two models can be used as adsorption surfaces to execute step 25;
s25, calculating the relative distance between the adjacent surfaces of the model B and the model A (the adjacent surfaces of the two models are regarded as adsorption surfaces of the two models), comparing the absolute value with a preset adsorption distance threshold d, and executing step 26 when the absolute value of the relative distance between the adjacent surfaces of the model B and the model A is smaller than or equal to the preset adsorption distance threshold d;
the relative distance between the adjacent surfaces of the model B and the model A is obtained by the following method:
the straight lines of the corresponding sides of the projection surfaces of the model A and the model B are represented by an equation Y=kX+C, a straight line equation YA=kX+C1 of the model A and a straight line equation YB=kX+C2 of the model B are obtained, k represents the slope, since ka=kB, the k values of the two straight line equations are estimated through a mathematical formula to be identical, only the C values are different, the C values represent the distance from the intersection point of each straight line and the Y axis to the origin, namely the relative position of each straight line, in the top view of the XY surface, the projection straight lines of the adjacent surfaces of the model A and the model B are respectively a straight line A3A4 and a straight line B1B2, and the relative distance between the two straight lines is the relative distance between the adjacent surfaces of the model B and the model A and is represented by C2-C1;
when the operator moves the model a, the value of C1 will change in real time, and similarly, when the operator moves the model B, the value of C2 will change in real time, in this embodiment, taking the adsorption model a of the moving model B as an example, the system calculates the relative distance between the adjacent surfaces of the model B and the model a in real time during the movement, compares the absolute value of the relative distance between the adjacent surfaces of the model B and the model a with the preset adsorption distance threshold d, and when the model B moves to satisfy the condition that |c2-c1| is less than or equal to d, step 26 is executed.
The preset adsorption distance threshold d is set by a platform or a user in a self-defining way, represents dynamic parameters of the adsorption distance between models, and can be adjusted according to actual conditions and user experience.
It should be noted that when two models penetrate each other, the result of C2-C1 is negative, so that the absolute value should be taken for calculation when the threshold value is determined.
S26, the system is automatically set, C1=C2 is enabled, and two straight lines of projection straight lines A3A4 and B1B2 of adjacent surfaces of the model A and the model B are controlled to coincide, so that automatic adsorption between the model A and the model B is achieved.
