Abstract

The invention relates to a volume detection method and a volume detection device, wherein the detection method comprises the steps of capturing an image of a mark of a device to be detected by an image capturing module, converting the image into an image signal and transmitting the image signal to a control unit. An audio signal receiving module receives the sound emitted by the device to be tested, converts the sound into an audio signal and transmits the audio signal to the control unit. The control unit compares the image signal with the actual shape and size of the mark by using detection software, calculates a distance value between the image acquisition module and the device to be detected, and obtains a standard volume value corresponding to the distance value. The control unit filters the sound signal by the detection software to obtain an actual volume value, compares the actual volume value with the standard volume value and judges whether the actual volume value exceeds the standard volume value.
