The camera device starts to shoot the video after receiving the shooting starting instruction, and starts to acquire video data; the method specifically comprises the following steps: the camera device is provided with a plurality of cameras inside the dynamic identification intelligent cabinet, and when the signal transceiver that the tray within the shooting range of the camera corresponds receives and sends unusually, the camera receives and begins to shoot the video after beginning to shoot the instruction, acquires corresponding video data.
When the transceiver receives and transmits normal signals, the controller cannot receive the shielding signals, and then the controller sends a shooting stopping instruction to the camera device; the method specifically comprises the following steps: the signal transceiver does not shield, the signal transceiver can complete normal signal transceiving, the detection device detects that the signal transceiver of the dynamic identification intelligent cabinet does not shield according to the condition that the signal transceiver can complete signal transceiving, and a shielding signal is not sent to the controller.

Suppose that the duration of normal shopping video shooting at the dynamic recognition intelligent cabinet is the total length, the video starts shooting when opening the door, and stops shooting when closing the door. However, the duration of the shot video is the invalid duration from the time when the consumer opens the door to reach the hand, and from the time when the consumer takes the goods out of the cabinet to close the door. That is, the head and tail durations of the currently shot dynamic video belong to the invalid duration. The invalid time length, algorithm or manual work can not be used as the identification and judgment basis. Only the period from the time when the consumer stretches out to pick the goods to the time when the cabinet body is taken out belongs to the effective time, and the method can be used for algorithm or artificial commodity identification judgment basis.
The method mainly eliminates the video shooting with invalid time duration, thereby greatly reducing the volume of the shot video and reducing the flow consumption during the uploading of the video. The following describes how the present invention starts video shooting from the time of reaching and ends video shooting when a commodity is taken out.
First, an infrared transceiver, i.e., an infrared sensor, needs to be installed on the inner door frame of the dynamic intelligent cabinet, and a pair of trays is installed at each layer, as shown in fig. 2. When the receiving and sending devices are not shielded, the infrared ray is normally transmitted and received without electric signals; when the receiving and sending devices are shielded, the infrared ray is abnormal in receiving and sending, and a shielding signal is sent to the controller. The controller sends a video shooting instruction to the camera to start shooting videos. 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 ray receiving and transmitting device on the layer is shielded, the infrared device triggers a shielding signal to be transmitted to the controller, and the controller gives an instruction to start video shooting. When the goods are taken out by the consumer, the infrared device shields the disappearance of the signal after the goods are taken out of the intelligent cabinet, and the controller gives an instruction to stop video shooting. The video shot at this time is a complete purchase process from the time of reaching for picking up the goods to the time of picking up the goods by the consumer, and belongs to the part of effective duration. The shooting is not carried out in the two sections of invalid time duration from the time of opening the door to the time of extending the hands into the cabinet and from the time of taking out the commodity to the time of closing the door.
By only shooting the video of the effective duration part of each order, the volume of the shot video can be greatly reduced, and the flow consumption of uploading the video is reduced.
