An instrumentation image analyzing system includes an image capturing device, a processor connected to the image capturing device, and a communication module connected to the processor, which replaces visual observation work of human by image analyzing technique for saving costs of manual visual observation as well as reducing the error rate of detection and enhancing the efficiency of detection. The image capturing device captures an image of at least one instrumentation to obtain an instrumentation image. The processor loads a program to perform an instrumentation identifying module which identifies the instrumentation image to generate an instrumentation information. The communication module transmits the instrumentation information to an external device.
