S220, for each target object, determining a first vector length of the target object relative to a first vector axis and a second vector length of the target object relative to a second vector axis under a set vector coordinate system according to the datamation curve and the attribute information.
Specifically, a UV coordinate system is used in setting a vector coordinate system, which describes the position of a point on a curved surface. The first vector axis may be a horizontal direction vector axis U-axis in the UV coordinate system. The second vector axis may be a vertical direction vector axis V axis in the UV coordinate system. The first vector length may be a length of the target object in the direction of the U-axis vector. The second vector length may be a length of the target object in the V-axis vector direction.
Specifically, for each target object, the vector length of each vector axis is calculated by using the two-dimensional array point sets UPts and VPts according to the data curve and the attribute information. Using the data points of the first row in the UPts, the length ulongth of the line connected by the first row of point sets is calculated as a first vector length relative to the first vector axis. Using the data points of the first row in the two-dimensional array point set VPts, the length VLength of the line connected by the first row point set is calculated as the second vector length with respect to the second vector axis.
Based on the optimization, the embodiment of the disclosure may determine, according to the datamation curve and the attribute information, that the first vector length of the target object relative to the first vector axis and the second vector length relative to the second vector axis in the set vector coordinate system are specifically optimized as follows:
a1 B-spline curves are determined as databased curves.
b1 Based on the attribute information), a first set of vector vertices of the B-spline curve relative to the first vector axis and a second set of vector vertices relative to the second vector axis in the set vector coordinate system are determined.
c1 A first vector length is determined from the first vector vertex set and a second vector length is determined from the second vector vertex set.

Wherein, both vector vertex sets are two-dimensional array vertex sets. For each target object, the length of the line connected by the first row of point sets is calculated as a first vector length relative to the first vector axis from the first row of data points in the first vector vertex set. Using the data points of the first row in the second vector vertex set, the lengths of the lines connected by the first row of point sets are calculated as second vector lengths relative to the second vector axis.
S230, determining a stretching curve set and a section curve set of the target object according to the first vector length and the second vector length.
Specifically, the first vector length ulongth and the second vector length VLength are compared, and whether the stretching curve set and the section curve set of the target object are formed by vertexes in the V-direction vector vertex set or formed by vertexes in the U-direction vector vertex set is determined according to the length relation between the first vector length ulongth and the second vector length VLength.
Based on the optimization, the embodiment of the disclosure may determine, according to the first vector length and the second vector length, a set of stretching curves and a set of cross-section curves of the target object, where the steps include:

Specifically, if the first vector length is greater than the second vector length, the extension direction of the target object may be considered as a U direction, and the vertices in the first vector vertex set are used to form a set of stretching curves of the target object, and the vertices in the second vector vertex set are used to form a set of cross-sectional curves of the target object. If the first vector length is less than or equal to the second vector length, the extension azimuth of the target object can be considered as V-direction, then the set of tensile curves of the target object is formed by adopting the vertexes in the second vector vertex set, and the set of cross-sectional curves of the target object is formed by adopting the vertexes in the first vector vertex set.
S240, determining corresponding stretching curve central lines according to the stretching curve sets of each two target objects in the digital engineering modeling model.
In particular, the centerline of the stretch curve may be a curve that is composed of the center points of the various locations in the stretch curve set. The number of cables in the digital engineering modeling model is large, and intersection inspection needs to be carried out between every two cables. Therefore, for every two target objects in the digital engineering modeling model, based on the two obtained target object stretching curve sets, key points of each position are taken for each target object stretching curve set, center points are calculated, and a curve formed by all calculated center points is taken as a stretching curve central line.
S250, determining corresponding section curve center lines based on the section curve sets of the two target objects respectively.
In particular, the cross-sectional curve centerline may be a circular curve.

And S260, according to the central line of each stretching curve and the central line of each section curve, carrying out intersection inspection on the two target objects, and obtaining an intersection inspection result.
Specifically, the distance between two target objects is calculated according to the central line of each stretching curve, and the respective radius of each target object is determined according to the central line of each section curve. According to the comparison result of the distance between two target objects and the sum of the section radius of the two target objects

And determining the respective section radiuses according to the section curve central line, and respectively serving as the target object radiuses of the two target objects. In practical application, considering the actual construction requirement, an error value can be set, and the sum of the radius of the two target objects and the set error value is compared with the minimum distance between the central lines. And obtaining an intersection inspection result according to the comparison result.
Based on the optimization, the embodiment of the disclosure can perform intersection inspection on two target objects according to the centerline of each stretching curve and the centerline of each section curve, and obtain an intersection inspection result, which is specifically optimized as follows:
a3 A centerline minimum distance between the two tensile curve centerlines is determined as the target object distance for the two target objects.
In particular, the midline minimum distance may be the distance between the closest two points between the midlines. The target object spacing may be a mutual distance between the target objects. And (3) calculating the intersection point of the central line and the vertical plane of the obtained stretching curve, and calculating the distance between the intersection points of the two curves and the vertical plane as the target object distance of the two target objects.
b3 A cross-sectional radius of a centerline of the two cross-sectional curves is determined as a target object radius of the two target objects, respectively.
In particular, the cross-sectional radius may be a radius given to a centerline of the cross-sectional curve. And calculating a circle passing through the three characteristic points according to the three characteristic points of the central line of the section curve, wherein the radius of the circle is the radius of the target object.
c3 Determining the sum of the radii of the two target objects and the set error value to obtain the object radius sum.
