[0048] Embodiment 1

[0049] Figure 1 1 is a schematic diagram of the structure of an inventory system provided by an embodiment of the present invention. The inventory system includes: a target detection device 110, a first processing device 120 and a switching device 130; wherein the first output port 111 of the target detection device 110 is connected to the first input port 121 of the first processing device 120, the second output port 122 of the first processing device 120 is connected to the second input port 131 of the switching device 130, and the switching device is connected to the first target display device through a preset interface;

[0050] The target detection device 110 recognizes the image of the inventory object and determines the inventory data of the inventory object, where the inventory data includes the type and quantity of the inventory object; the target detection device 110 transmits the inventory data to the first processing device 120 through the first output port 111; the first processing device 120 transmits the inventory data to the first target display device through the second output port 122 via the adapter; the first target display device displays the inventory data.

[0051] In this embodiment, the inventory objects can be understood as the storage objects in the warehouse. Taking the power business as an example, the inventory objects can be the safety tools stored in the warehouse, such as but not limited to arc protection clothing, grounding wires, insulating baffles and insulating gloves.

[0052] The target detection device 110 can be understood as an electronic device with a target detection function, such as a microcomputer or a mobile terminal. The device type of the target detection device 110 is not limited here. The mobile terminal here can include devices such as mobile phones and tablets, which can support the target detection function. The microcomputer here can include a processor or a chip, etc., and the specific type of the microcomputer is not limited, as long as it can support the target detection function.

[0053] The target detection device 110 obtains an image of the counted object, wherein there may be multiple images of the counted object. The image of the counted object may be acquired by a camera, and the camera is connected to the target detection device 110 by wire or wirelessly.

[0054] Optionally, a timing task is provided in the target detection device 110. In response to the timing task, an image acquisition instruction is sent to the camera so that the camera acquires an image of the inventory object and transmits the image of the inventory object to the target detection device 110. In some embodiments, the camera is arranged in the warehouse, and there may be one or more cameras. The inventory data in the warehouse is located within the shooting range of at least one camera. The camera acquires an image of the inventory object in response to the image acquisition instruction. In some embodiments, the camera is arranged on a mobile device, and the mobile device may be a mobile robot. The mobile robot may drive the camera to move in the warehouse. For example, the mobile robot is pre-loaded with warehouse path information, and the warehouse path information includes image acquisition points. The mobile robot drives the camera to move based on the warehouse path information, and stops when it moves to each image acquisition point. The camera acquires an image of the inventory object when the mobile robot stops moving.

[0055] In this embodiment, the image of the inventory object in the warehouse is collected by the camera to provide a basis for the warehouse inventory. Optionally, there can be multiple images of the inventory object, and any image can include one or more inventory objects.

[0056] The target detection device 110 is configured with a target detection model, which performs target detection on the image of the inventory object through the target detection model, determines the type and quantity of the inventory object, and forms inventory data. The target detection model can be a machine learning model, for example, a neural network model, which is obtained by training a training data set, wherein the training data set may include sample images and detection labels of the sample images, and the sample images may be images of historical inventory objects in the warehouse. Optionally, the target detection model can be a Yolov5-lite model. The training data set is divided into a training set and a validation set, and the training is performed using a random batch gradient descent algorithm, and finally a highly accurate target detection model is obtained.

[0057] Optionally, the image of the inventory object is input into the target detection model to obtain the detection result output by the target detection model, and the detection result includes the type and quantity of the inventory object in the image. The detection results corresponding to the images of at least one inventory object respectively form inventory data. The inventory data includes at least one type of inventory object and the quantity corresponding to the type. Taking the inventory object as safety tools in the power business scenario as an example, the types of inventory objects include but are not limited to arc protection clothing, foot buckles, grounding wires, insulating baffles, insulating boots, insulating gloves, insulating ropes, insulating telescopic ladders, and insulating mats. Taking the inventory object as a type including n types as an example, the target detection model can include n detection heads, and each detection head can be used to identify the probability that the inventory object in the image belongs to a certain type.

[0058] Specifically, for any image of an inventory object, determine the detection result corresponding to the image of the inventory object, and store the detection result in the inventory data table. Determine in the inventory data table whether the type of the inventory object in the detection data has been stored. If so, update the quantity corresponding to the type of the inventory object in the inventory data table based on the quantity in the detection data, that is, the sum of the quantity corresponding to the type of the inventory object in the inventory data table and the quantity in the detection data as the updated quantity corresponding to the type of the inventory object; if the inventory data table does not include the type of the inventory object in the detection data, add the type and quantity of the inventory object in the inventory data table. Until all the images of the inventory objects are detected and the inventory data table is updated, the type and quantity of the inventory quantity in the inventory data table form the inventory data.

[0059] In some embodiments, a label is configured on the inventory object; the image of the inventory object includes the label of the inventory object. The label here can be an image label, which is used to identify the inventory object. The label can be used to characterize the type of the inventory object.

[0060] The target detection device 110 detects the labels in the image of the inventory object through the target detection model, determines the type and quantity of the inventory object, and forms the inventory data. Optionally, the image of the inventory object is sub-imaged, and the sub-image includes the label of the inventory object. The sub-image is input into the target detection model to obtain the type of the inventory object. The number corresponding to each type of the inventory object is counted to obtain the inventory data.

[0061] In some embodiments, a sub-image is captured from the image of the inventory object, and the captured sub-image and the image of the inventory object are input into a target detection model, so that the target detection model can comprehensively determine the type and quantity of the inventory object through the labels in the sub-image, the structural features and texture features of the inventory object in the image of the inventory object, thereby improving the accuracy of the inventory data.

[0062] The target detection device 110 is connected to the first processing device 120, wherein the target detection device 110 is configured with a first output port 111, and the first processing device 120 is configured with a first input port 121.

[0064] The first processing device 120 is also configured with a second output port 122, and the second output port 122 of the first processing device 120 is connected to the second input port 131 of the adapter 130. The adapter is connected to the first target display device through a preset interface, and the target display device can be a computer or a mobile terminal, and the mobile terminal can be a tablet computer, a mobile phone or a PC, etc. Correspondingly, the preset interface can be an interface configured by the first target display device, for example, a USB interface.

Optionally, the connecting line between the first processing device 120 and the adapter device 130 is a retractable connecting line to support the connection relationship between the first target display device and the first processing device 120 located at different positions.

[0066] The first processing device 120 transmits the inventory data to the adapter device 130 through the second output port 122, and the adapter device 130 converts the inventory data into a data format suitable for support by a preset interface, thereby realizing transmission of the inventory data to the first target display device.

[0068] It can be understood that the inventory data output by the first processing device 120 is in a different format from the data signal receivable by the first target display device. For data transmission between the first processing device 120 and the first target display device, the inventory data is converted into a preset interface signal supported by the preset interface of the first target display device through the adapter 130.

[0069] The set type is the data type supported by the adapter 130 for processing, and the inventory data is converted into signal data of the set type through the signal conversion circuit to support the subsequent signal processing process.

The CH340 chip includes an output pin, namely pin 3, which is connected to the preset interface through pin 3 to transmit the preset interface signal to the first target display device through the preset interface.
