a data flow consumption optimization method for dynamically identifying intelligent cabinets, as shown in FIG. 1, comprises the following steps:
the method comprises the steps that signal receiving and transmitting devices are arranged on two sides of the inside of the dynamic identification intelligent cabinet, a plurality of signal receiving and transmitting devices are arranged, a pair of signal receiving and transmitting devices are respectively arranged at the positions of each layer of tray on the inner door frame of the dynamic identification intelligent cabinet, and signals are acquired through the signal receiving and transmitting devices;

After receiving the shielding signal, the controller sends a shooting starting instruction to the shooting device; the method comprises the following steps: the controller receives the shielding signal sent by the detection device, and judges that the dynamic identification intelligent cabinet is started, and meanwhile, the receiving and transmitting signal devices of the kth tray are shielded, and then the controller sends a shooting starting instruction to the shooting device corresponding to the kth tray.
When the camera device receives a shooting starting instruction, shooting video is started, and video data is started to be acquired; the method comprises the following steps: the camera is provided with a plurality of cameras inside the dynamic identification intelligent cabinet, when the signal receiving and transmitting device corresponding to the tray in the shooting range of the cameras receives and transmits abnormality, the cameras start shooting videos after receiving shooting starting instructions, and corresponding video data are obtained.
When the receiving and transmitting device receives and transmits normally, the controller can not receive the shielding signal, and then the controller transmits a shooting stopping instruction to the camera device; the method comprises the following steps: the signal receiving and transmitting devices are not shielded, the signal receiving and transmitting devices can complete normal signal receiving and transmitting, the detection device detects that the signal receiving and transmitting devices of the dynamic identification intelligent cabinet are not shielded according to the condition that the signal receiving and transmitting devices can complete signal receiving and transmitting, and then shielding signals are not sent to the controller.

And assuming that the normal shopping video shooting duration of the dynamic identification intelligent cabinet is the total length, shooting the video from the time of opening the door, and stopping shooting when the door is closed. However, for the duration of the video shot, from the time the consumer opens the door to reach the hand, from the time the goods are taken out of the cabinet to the time the door is closed, all belong to the duration of invalidity. Namely, the head and tail time lengths of the currently shot dynamic video are all invalid time lengths. For invalid time length, neither algorithm nor manual work can be used as a recognition judgment basis. Only the period from the time when the consumer stretches the hand to take the goods to the time when the consumer takes the cabinet body out belongs to the effective duration, and the method can be used for algorithm or artificial commodity identification judgment basis.
The invention largely reduces the volume of the shot video and reduces the flow consumption when uploading the video by eliminating the video shooting with invalid duration. The following describes how the invention can start video shooting from the time of stretching hands and end video shooting when goods are taken out.
First, an infrared transceiver, that is, an infrared sensor, is installed on the inner door frame of the dynamic intelligent cabinet, and a pair of trays are installed at each layer, as shown in fig. 2. When no shielding exists between the receiving device and the transmitting device, the infrared ray is normally received and sent, and no electric signal exists; when shielding exists between the receiving device and the transmitting device, infrared ray is abnormal in receiving and transmitting, and shielding signals are sent to the controller. The controller sends a video shooting instruction to the camera to start shooting video. When the shielding signal disappears, the controller sends a shooting stopping instruction to the camera to stop video shooting.
When a consumer stretches into a certain layer of tray to pick up goods, the infrared receiving and transmitting device of the layer is shielded, the infrared device triggers the shielding signal to be sent to the controller, and the controller instructs to start video shooting. When the customer finishes taking goods, after taking the goods out of the intelligent cabinet, the shielding signal of the infrared device disappears, and the controller gives an instruction to stop video shooting. The video shot at this time is the complete purchasing process of the consumer from picking up goods by hand to picking up the goods, and belongs to the part of the effective duration. And the part of the ineffective time period from the opening of the door to the extension of the hand into the cabinet and the part from the taking out of the commodity to the closing of the door are not shot.
By shooting only the video of the effective duration part of each order, the volume of the shot video can be greatly reduced, and therefore the flow consumption of uploading the video is reduced.
