Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The invention provides an embodiment shown in fig. 1, which provides a post intelligent shelf system guiding system with acousto-optic guiding, comprising a guiding device, wherein the guiding device comprises a strategy generating module, a control module and a plurality of indicator lamps;

generating a control scheme based on the display duration:

When the control scheme is generated, the original display sequence of the indication colors still displayed in the next display period is reserved, so that the adjacent same display interval is kept as much as possible, the experience of the pick-up person is better, and the indication effectiveness is stronger. Because if the display order is disturbed in the next display period, there is a possibility that an indication color is just displayed in the previous display period, the next display period starts to display again, so that the time interval for the next display is not fixed, the user experience is poor, and the validity of the provided guidance is poor.

Alternatively to this, the method may comprise,and->The values of (2) are 0.4 and 0.6, respectively.

Alternatively, the preset age may be 150.

Optionally, the predetermined length is a maximum value of a distance between a storage location in the post and a predetermined departure location from which the picking-up of the item is performed.

Specifically, the preset departure location may be a doorway of a post.

Optionally, the indicator lights are arranged along the surface of the shelf, and the heights of two adjacent indicator lights are the same.

The indicator light can display a plurality of colors.

Alternatively, the display period may be 2 seconds.

Optionally, adding an element in the sequence D to the sequence C to obtain an updated sequence C, including:

the sequence number of the last element in the sequence C is denoted by h,

then for the kth element in sequence D, after it is added to sequence C, its corresponding sequence number is h + k.

Optionally, as shown in fig. 2, the device further comprises an acquisition device;

Specifically, the identity information is reserved information when the sender registers in the sender system of the post.

The post account number is not necessarily a mobile phone number, but can be a mailbox, a self-organized account number and the like.

the shooting module is used for acquiring a face image of the pick-up person;

Optionally, acquiring a face image of the person to be fetched includes:

continuously shooting the face of the person to be picked up to obtain a plurality of face images;

the face image of the person is selected from the plurality of face images by adopting the following modes:

s1, sequencing all obtained face images according to the sequence from the early to the late of shooting time;

s2, calculating image quality values of the 1 st and 2 nd face images;

s3, calculating an image quality value of a kth face image for the kth face image; k is greater than or equal to 3;

s4, calculating the difference value of the image quality values between the kth-1 human face image and the kth-2 human face imageCalculating the difference of the image quality values between the kth face image and the kth-1 face image>The method comprises the steps of carrying out a first treatment on the surface of the If it isS5 is entered, otherwise S6 is entered;

s5, judging whether the value of k is smaller than numk, wherein numk is the total number of face images obtained through continuous shooting, if so, adding 1 to the value of k, entering S3, and if not, entering S6;

s6, taking the kth face image as the face image of the pick-up person.

When the face image is acquired, the face image is not acquired in a single shooting mode, and because the head of the person to be shot is moved easily to acquire a blurred image in the single shooting, the probability of acquiring the face image with higher quality is improved by continuously shooting the face image, the success rate of face recognition of the face image acquisition method is improved, the fact that the person to be shot consumes too much time on the face image to be shot is avoided, and the picking efficiency is improved.

After the plurality of face images are acquired, the image quality of each face image is not calculated, because the moment when the head of the person taking the face image stops moving after moving is uncertain, and the moving can be stopped when the continuous shooting is not finished, and the image quality reaches the highest value. Therefore, if the head stops moving immediately after the start of continuous shooting, for example, if the number of sheets in continuous shooting is 20 and the head stops moving when the 5 th sheet is shot, calculating the image quality value for the remaining 15 face images is wasteful.

Therefore, the invention judges the change trend of the quality values of the adjacent 3 face images, and when the difference value of the image quality values of the adjacent two face images is not increased, the invention stops calculating the image quality values of the rest face images, thereby enabling the face images with high enough quality to be determined more quickly to be used as the face images of the pick-up person.

Optionally, the calculating process of the image quality value includes:

acquiring a skin region belonging to a face image by adopting a skin color detection algorithm;

the image quality value is calculated using the following function:

representing image quality value, +.>Representing the number of pixels of gray scale v in the skin area,representing the number of pixels in the skin area.

Specifically, in the process of calculating the image quality value, it is calculated by calculating the number of occurrences of the pixel point for each gradation, respectively. When the number difference of the pixels of different gray scales is larger, the information contained in the image is richer, and the quality is higher. In addition, the invention does not directly calculate the image quality value of the whole image, because the background area exists in the image, the background area does not contain useful information, and if the image quality is calculated based on the whole image, the quality condition of the face part in the obtained face image can not be well represented, therefore, the invention firstly obtains the skin area through the skin color detection algorithm; and then, calculating an image quality value based on the skin region, so that the image quality value can more accurately represent the richness of the information contained in the face region in the face image, and the face image with better face region quality can be selected.

Optionally, the query module includes a face image storage unit and a matching unit;

the face image storage unit is used for storing face images and identity information of persons registered in the picking system of the post;

the matching unit is used for matching the face image obtained by the shooting module with the face image stored in the face image storage unit to obtain the identity information of the pick-up person.

Specifically, when the pickup system of the post registers, the pickup person can input the face image first, so that the pickup is convenient to be carried out through the face directly later, and the pickup is faster.

Optionally, as shown in fig. 3, the device further comprises a retrieval device;

Specifically, the location database also includes the number of the express bill of the express to be fetched.

Optionally, as shown in fig. 4, the system further comprises a path generating module;

Specifically, the intersection point of the channels between the shelves is taken as a passing point, the channels between two adjacent passing points are taken as edges, and the path between the storage position and the preset departure position can be generated by adopting a path generation algorithm.

Path generation algorithms belong to existing technologies, such as Dijkstra's algorithm, bellman-Ford algorithm, etc.

In particular, the indicator lamps may be installed at the edge of the shelf at equal intervals, for example, at a height of 1.6 meters in a unified manner, so that the indicator lamps may indicate paths from a preset departure position to respective storage positions.

Alternatively, the storage location may include the number of shelves and the tier number of shelves, e.g., 0608, representing tier 8 of shelf 6.

acquiring a set f of numbers of the indicator lights corresponding to e;

Specifically, since the sequence C has different display orders of the indication colors, the display time period of each indication delay can be calculated according to the display time period of each indication color.

For example, the start time of the local t+1 display periods isThe display period of element 1 z in sequence C is +.>，/>Representing the duration of the display of element z.

Optionally, the indicator light in the control set f displays a color corresponding to the d-th element, including:

the display sequence of the indicator lights in the set f is controlled according to the distance between the positions of the indicator lights in the path and the storage positions in the path, and the indicator lights with larger distance between the storage positions in the path are displayed earlier.

Specifically, the indication lamp is controlled to be on or off asynchronously, so that the direction indication is further provided. So that the pick-up person can move along the direction of the lighted indicator light.

Optionally, the device also comprises a code scanning module;

the code scanning module is used for scanning the bar codes on the express delivery which are picked up by the pick-up person to obtain the express bill number;

the single number of the express delivery is sent to a first updating unit;

the first updating unit is used for acquiring a path corresponding to the express bill number.

Specifically, after the first updating unit acquires the paths according to the single number, the corresponding paths are deleted from the guide path set, so that the guide path set is updated.

Optionally, the retrieving device further comprises a database management unit, and the code scanning module is further used for sending the express bill number to the database management unit;

the database management unit is used for deleting the data corresponding to the express bill number from the position database.

Optionally, the device also comprises a monitoring device;

the monitoring device is used for counting the accumulated display times of each indication color, and playing a preset alarm sound if the accumulated display times exceed a set quantity threshold value.

Specifically, the alarm sound is used for prompting that the manager of the post station does not get the express for a long time, and at the moment, the manager of the post station can help the sender, so that the sender can finish the picking more quickly.

Specifically, the set number threshold may be 30.
