Abstract

The invention discloses a product attitude determination method and device. The method comprises the following steps that a line laser device is controlled to project line laser to a target product; image acquisition equipment is controlled to obtain a light stripe image sequence on the product surface of the target product in a projection scene of the line laser; three-dimensional information ofeach light stripe image in the light stripe image sequence is extracted and three-dimensional point cloud data of the product surface of the target product is obtained based on the three-dimensional information; according to the three-dimensional point cloud data, a parallax image of the product surface of the target product is obtained, and the current attitude of the target product is determinedbased on the parallax image; and the attitude of a predetermined executing mechanism is adjusted based on the current attitude of the target product. The product attitude determination method and device solve the technical problem that the reliability of a manner of determining the attitude of the product in the related technology is relatively low.

Description

technical field [0001] The present invention relates to the technical field of product posture processing, in particular to a method and device for determining product posture. Background technique [0002] For products randomly placed on the dynamic assembly line, in order to realize intelligent and flexible production, such as automatic assembly, automatic screwing, automatic labeling, automatic detection, etc., the premise is to be able to obtain the posture of the product on the dynamic assembly line in real time, and then control The actuators, such as robots, X / Y / Z platforms, modules, fixtures, etc., adjust the posture of the mechanism in real time according to the posture of the product, maintain a unified relative posture with the product, and finally execute the corresponding corresponding path with the designed relative path. action. At present, the commonly used method is to install the contact method of guiding mechanism on the dynamic assembly line, and then gu...
