摘要
In this article an efficient pointer recognition algorithm is proposed to identify the pointer and it is used in real-time testing the scale of the dashboard pointer. The algorithm can be used to identify any type of dashboard pointer such as red color pointer, yellow color pointer and white color pointer etc. Pointer recognition is divided into two parts; configuration and testing. The parameters are required in testing of the dashboard such as the minimum, maximum and nonuniform scale of the dashboard. These parameters are collected in the configuration interface. These parameters are loaded when testing. The scale value of pointer is calculated according to the parameters after pointer position is detected. Configurations are setup for different types of dashboard so that any types of dashboard pointer can be detected. If all the scale values of the test points are correct values within an allowable error and the instrument is considered qualified during the test. Otherwise that the instrument is considered to be defective. Finally pointer recognition algorithm is applied to automobile instrument quality detection and has achieved good results.
