The invention relates to a volume detection method and a volume detection device. The volume detection method comprises the steps of capturing an image of a mark of a to-be-tested device through a video capture module, converting the image of the mark into an image signal, transmitting the image signal to a control unit, receiving sound generated by the to-be-tested device through an audio receiving module, converting the sound into a sound signal, transmitting the sound signal to the control unit, comparing the image signal with the actual shape and size of the mark through a detection software by the control unit, calculating a distance value between the video capture module and the to-be-tested device, obtaining a standard volume value corresponding to the distance value, filtering the sound signal through the detection software by the control unit, obtaining an actual volume value, comparing the actual volume value with the standard volume value, and judging whether the actual volume value exceeds the standard volume value or not.
Description
【Technical field】 [0001] The invention relates to a detection method and a detection device, in particular to a volume detection method and a volume detection device which can be easily operated by a user. 【Background technique】 [0002] At present, the common volume detection devices on the market use the radio module to directly receive the sound of the environmental sound source and convert it into a sound signal. The detection software obtains the corresponding volume value according to the received sound signal, and compares it with the standard volume value to judge the environment. Whether the volume of the sound source exceeds the standard volume value, since the general volume detection method is to directly receive the sound of the environmental sound source, it cannot be detected for a specific device. [0003] Therefore, if it is desired to measure the volume of a certain device under test, the volume detection devices currently seen cannot effectively eliminate ...
