        Mushroom cultivation is one of the important industries in Taiwan's agriculture. In current mushroom cultivation process, which includes spawn production, substrate preparation & bottling, inoculation, spawning, scratching, fruiting, harvest and packing, required a large amount of labor. In this research, the improvement in fault inspection for spawn level and bacterial infection before scratching process was conducted. The aim of this research is to establish an inspection system using machine vision, pneumatic mechanism and Programmable Logic Controller (PLC). First, an experiment-used small lighting chamber was made to study the image processing method, which can get the development (expansion) of self-made simulated samples from its side view image. The accuracy to recognize the fault in self-made simulated samples is up to 99.9%. In real cultivation bottle samples fault inspection, it spent for about 10 seconds and can get well recognition. A prototype of sorting system has also been established to conduct the inspecting process and remove bottles with fault conditions of spawn level and bacterial infection.
