Abstract

The invention provides an ICT automatic test machine control system suitable for a PCB, and the system comprises an image collection module which is used for positioning the PCB, carrying out the all-dimensional surrounding image collection of the PCB, and obtaining a PCB image, and an ICT test module which is used for automatically recognizing a component of the PCB image, carrying out the region segmentation according to the component, determining a component subregion, and carrying out the detection of the component subregion. The partition test module is used for carrying out partition test on the PCB image and carrying out automatic comparison and difference calculation with a standard component partition image to generate a partition automatic test result, and the test result feedback module is used for receiving the partition automatic test result, summarizing the automatic test results of all partitions and generating and feeding back a total result. The limitation of the model of the PCB is avoided, and the PCB of different models can be automatically tested.
