Abstract

The invention relates to an automobile roof cloth synchronous tensioning method and a tensioning structure thereof. The tensioning structure is characterized by comprising a tensioning table, a roof cloth clamping module, a tensioning connecting rod and a tensioning transmission plate; high-risk areas where local wrinkles and unevenness are prone to occurring in the ceiling cloth are identified through data; applying a topological optimization algorithm to design tension points on the ceiling cloth tension structure; establishing a three-dimensional entity model of the ceiling cloth tension structure in computer aided design software according to the optimized tension point parameters; in the tensioning process, the shape and stress distribution of the ceiling cloth are monitored in real time through the machine vision technology; feature points on the surface of the ceiling cloth are extracted through an image processing algorithm, and displacement and dependent variables of the feature points are calculated to judge whether an expected tensioning effect is achieved or not; if it is monitored that the ceiling layout part is wrinkled or uneven, using a convolutional neural network to analyze shape features of a wrinkled area; and after tensioning is completed, a three-dimensional scanner is used for obtaining point cloud data of the surface of the ceiling.
