Although progress has been made on algorithms to automate sensory inspection based on machine learning, there are several problems yet to be overcome. We have developed an on-line hammering sound inspection system for an automobile product. Since an upper limit is set on the inspection time (per part), a support vector machine method, which is able to compute quickly, is applied to the on-line inspection. The experimental results show that the accuracy of inspection reaches 99.8% within the specified processing time. This paper reports on the implementation of the hammering sound sampling process, the inspection model training process, and the instrumentation of inspection system.
