Automatic classification method for images of automobile gear shifting panel

Abstract

The invention discloses an automatic classification method for images of an automobile gear shifting panel. The method comprises the following steps of collecting an image of the automobile gear shifting panel; carrying out binarization, expansion and hole filling, carrying out differential operation, and separating a target area; extracting eleven shape features of the target area and building the structure of an MLP neural network model to acquire model parameters and the trained MLP neural network model; extracting eleven shape features from an automobile gear shifting panel image of an unknown type and inputting the features into the MLP neural network model, and outputting the type of the automobile gear shifting panel. Different types of automobile gear shifting panels in the image can be classified, the classification rate of the automobile gear shifting panels is increased, and the method has good classification robustness and accuracy.

Description

technical field [0001] The invention relates to an automatic classification method for shift panels of automobiles of different models, in particular to an automatic classification method for shift panels of automobiles of different models by machine vision. Background technique [0002] As of September 2018, the number of motor vehicles in my country has reached 322 million. Based on the international scrap rate of 6%-7%, it is estimated that 20 million motor vehicles will be scrapped in my country in 2020. In June 2019, the new version of the "Measures for the Administration of Recycling of Scrapped Automobiles and Motor Vehicles" was officially implemented, which allows the parts in scrapped cars to be recycled again. As one of the recyclable parts of scrapped cars, the car shift panel not only plays the role of supporting the shift lever and marking the gear, but also affects the decorative effect of the car and the actual experience of consumers. However, judging from ...
