Embodiment Construction

[0029] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0030] see Figure 1 to Figure 8 , a calculation method for shoe upper glue spray trajectory, comprising the steps of:

[0031] Step 10. Scan a set of soles and uppers with a linear laser scanner to obtain two sets of point cloud data. Please refer to image 3 , image 3 It is a schematic diagram of the scanned sole and upper, the point cloud data is a matrix, the point cloud data of the sole is recorded as matrix B, and the point cloud data of the shoe upper is recorded as matrix D, and the two sets of point cloud data need to be registered The original point cloud pair; for example, the sole is a matrix B of double-precision data type of 17027×3, that is, a matrix B composed of 17027 three-dimensional space coordinates x, y, z. Similarly, the upper is a double-precision data of 18173×3 type of matrix D;

[0032] Step 20. Since th...

Abstract

The invention provides a calculation method for a vamp glue spray trajectory. The calculation method comprises the steps that firstly, a set of soles and vamps are scanned through a linear laser scanner, and two sets of point cloud data are obtained; secondly, arrays of original point cloud pairs are made to be identical in size through preprocessing; thirdly, rough matching is achieved through an SVD singular matrix decomposition method, accurate registration is achieved through an ICP algorithm after the point cloud pairs are identical in direction and become close to each other, and coordinate conversion relations between the point cloud pairs are obtained. Meanwhile, due to the practical production demands, local fitting deformation of a sole profile point cloud set is achieved through a Bezier curved line algorithm, the accurate calculation of the vamp glue spray trajectory is achieved, and thus glue spray automation is achieved.

Description

【Technical field】 [0001] The invention relates to the field of automation, in particular to a calculation method for a shoe upper glue spray trajectory obtained based on accurate registration of shoe sole and shoe upper point cloud pairs. 【Background technique】 [0002] At present, the automation level of my country's footwear industry is still relatively low. Especially in the glue spraying process, only a few enterprises use automation equipment in individual processes. Most of the glue spraying processes are still completed manually by workers. Problems such as labor shortage are becoming more and more prominent, and there is an urgent need to develop a mature automated intelligent glue spraying production line to promote the healthy development of the industry. The invention solves the key technology in the development of the intelligent glue spraying robot—glue spraying automation, and realizes the automatic calculation of the glue spraying position of the sole and vamp ...
