Marking build-up member may include three shaft parts, according to feature difference, part is divided into tri- sections of A, B, C, A sections have a hole characteristic
With an axis feature, B sections have an axis feature, and C sections have an axis feature, and wherein characteristic point a, b, c, d has recorded respectively
The start-stop position of shaft part, after dividing, each shaft part can regard an independent individual as, have the shaft part relative to the axis
The position of base part and bounding box information.
In specific implementation, in each of the bounding box information of each subassembly of the target build-up member of acquisition and reference cell
After the bounding box information of subassembly, using the subassembly of target build-up member as the first subassembly, by the subassembly of reference cell
As the second subassembly, according to the bounding box information of the bounding box information of the first subassembly and the second subassembly, difference each first
Space length between subassembly and each second subassembly, the command range that space length is less than set distance threshold value are corresponding
The first subassembly be determined as the component to collide with reference cell.
For example, it is respectively A1, A2, A3 that target build-up member, which includes 3 subassemblies, reference cell includes 2 subassemblies point
Not Wei B1, B2, each subassembly all has bounding box information, calculate separately A1 and B1, A1 and B2, A2 and B1, A2 and B2, A3 with
Space length between B1, A3 and B2, if the space length between the A1 and B1 that are finally calculated is less than word space threshold,
Then determine that the A1 subassembly of target build-up member and the B1 subassembly of reference cell are collided.

Axis rotation moves along a straight line along X-axis linear motion, along Y-axis, along Z axis linear motion etc..
According to setting constraint rule, when assembling the target build-up member in the reference cell, including following step
It is rapid:
The spy of at least one subassembly based on the corresponding target build-up member of space length for being less than set distance threshold value
Reference breath and the corresponding relationship between preset feature and constraint condition determine and the sky less than set distance threshold value respectively
Between the corresponding target build-up member of distance the corresponding constraint condition of at least one subassembly；
Based on the determining constraint condition, the target build-up member is assembled in the reference cell.
Here, constraint condition is pre-set, and when constraint condition is arranged, constraint condition can be set to forbid along X
Axis linear motion, forbid along X-axis rotary motion, forbid along Y-axis move along a straight line, forbid along Y-axis rotary motion, forbid it is straight along Z axis
Line movement is forbidden along Z axis rotary motion.
In specific implementation, the possible more than one of the subassembly that target build-up member and reference cell collide, is sending out
When the subassembly of raw collision has multiple, the characteristic information of the subassembly to be collided based on target build-up member and preset
Corresponding relationship between feature and constraint condition, determining at least one constraint item corresponding with target build-up member collision subassembly
Part assembles target build-up member according at least one determining above-mentioned constraint condition in reference cell.In this way, can image
Displaying target build-up member and referring to the movement relation between build-up member, improve the experience of user.
For example, continuing the example in step S102, the A1 subassembly and B1 subassembly in target build-up member are matching part
Part determines that constraint condition corresponding with A1 subassembly is to forbid according to the corresponding relationship between preset feature and constraint condition
Along Y-axis linear motion, forbid along Y-axis rotary motion, forbid along Z axis move along a straight line, forbid along Z axis rotary motion, it is, right
The translation of Z axis and the limitation of rotational freedom, and to the translation of Y-axis and the limitation of rotational freedom, so that A1 subassembly exists
Under the limitation of constraint condition, it is only capable of arriving at rigging position along X-axis straight line, rotary motion, is finally completed assembly.
