Vehicle body transfer method and system based on vehicle type recognition

Abstract

The invention relates to an automobile body transferring and hanging method and system based on automobile type recognition. The system comprises a background recognition device, a visual recognition device, a photoelectric correlation recognition device, an error prevention verification device and a transferring and hanging device. The background recognition device obtains vehicle type queue data of a to-be-recognized vehicle body to obtain a first vehicle type serial number; the visual identification device obtains a rear angle window contour image to obtain a second vehicle type serial number; the photoelectric correlation recognition device obtains a feature point photoelectric data set to obtain a third vehicle type serial number; the error prevention verification device compares the serial numbers of the three vehicle types; when the comparison is consistent, obtaining a target vehicle type serial number; the background identification device obtains a target transfer and hanging instruction data set according to the target vehicle type serial number; and the transfer hanging device is used for carrying out transfer hanging according to the target transfer hanging instruction data set to complete vehicle body transfer hanging. According to the method, the final vehicle body type is obtained from multi-mode vehicle type identification, the vehicle type identification efficiency and accuracy can be effectively improved, the misoperation risk is reduced, and collinear production of vehicle bodies of different vehicle types can be facilitated.

Description

technical field [0001] The invention relates to the field of automobile production and manufacturing, in particular to an automobile body swiveling method and system based on vehicle type identification. Background technique [0002] In the automotive field, as people have higher and higher requirements for vehicle options, iterative products and new products emerge one after another, and the types of models produced by OEMs are also increasing. In order to improve the capacity utilization rate of OEMs, an OEM often produces a variety of different types of models, and this mixed production of multiple models has high requirements for the identification of production line models, especially for the mixed flow of models with non-universal body platforms, the production line needs Adaptive adjustments are made according to the body structure of different models. For example, for the transfer process of the interior trim line to the chassis line hanger, the general car body is ...
