In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, it shows a flow chart of implementation of the sorting method for logistics packages provided by the embodiment of the present invention, and details are as follows:
in step 101, three-dimensional image information of a target parcel is acquired, wherein the three-dimensional image information at least comprises a plurality of three-dimensional coordinates of the target parcel in a predetermined scene.
In an automatic sorting scene of the logistics packages, the logistics packages can be placed on a conveyor belt, the conveyor belt is used for sequentially conveying the packages, a three-dimensional image sensor, such as a three-dimensional laser image sensor or a three-dimensional infrared image sensor, can be arranged at a specified position of the conveyor belt, a monitoring scene of the three-dimensional image sensor is a preset scene, when the conveyed packages pass through the preset scene, three-dimensional image information of the conveyed packages (namely target packages) is collected through the three-dimensional image sensor, and the three-dimensional image information at least comprises a plurality of three-dimensional coordinate information of the target packages in the preset scene. For example, for a package having a three-dimensional shape of a cube, the three-dimensional image information includes at least three-dimensional coordinate information of the positions of a plurality of vertices thereof.
Optionally, the step 101 may include:
acquiring two-dimensional plane image information of the target package overlooked in the preset scene;
acquiring height information of the target parcel in the preset scene;
and performing three-dimensional image reconstruction based on the overlooked two-dimensional plane image information and the height information to obtain the three-dimensional image information of the target package.
In the embodiment of the invention, two-dimensional plane image information of the target package overlooked in a preset scene can be acquired through a two-dimensional image sensor; height information of the target package in the preset scene can be acquired through a ranging sensor; therefore, three-dimensional image reconstruction is carried out based on the obtained overlooked two-dimensional plane image information and the obtained height information, the height information is used as a depth element of each pixel point on the two-dimensional plane image and is fused to the two-dimensional plane image, and the three-dimensional image information of the target parcel is obtained.
Optionally, the step 101 may include:
acquiring a reflection pattern of structured light of a specified pattern on the target package;
and calculating the three-dimensional image information of the target parcel based on the pattern deformation of the reflection pattern and the specified mode pattern.
In the embodiment of the invention, in a preset scene, the structured light of the specified mode pattern can be used for irradiating the target parcel, the reflection pattern of the structured light of the specified mode pattern on the target parcel is obtained, the shape of the target parcel can deform the specified mode pattern, and the three-dimensional image information of the target parcel can be obtained by calculating through the deformation.
For example, when the structured light projector projects structured light of a specified pattern (e.g., a bar pattern), if projected on a plane, the two-dimensional image obtained by the image sensor on the plane is still a bar pattern, and if an object (e.g., a parcel) exists on the projected plane, the two-dimensional image obtained by the image sensor on the plane will be a bar pattern with deformation. Then, by using various structured light principles and algorithms (e.g., triangulation principles), accurate three-dimensional surface information of an object on a plane can be calculated. That is, three-dimensional image information of the object can be obtained.
In step 102, the three-dimensional image information is input into a preset feature extraction model to obtain the three-dimensional geometric features of the target package.
In an embodiment of the present invention, the extracted three-dimensional geometric features at least include a length, a width, and a height of the object parcel in the predetermined scene, where the length, the width, and the height may respectively correspond to distances in three-dimensional coordinate directions in the predetermined scene.
In the embodiment of the invention, the key point information in the three-dimensional image information can be rapidly extracted by using the preset feature extraction model, so that the three-dimensional geometric feature of the target package is obtained.
Optionally, the feature extraction model is a convolutional neural network, and the convolutional neural network includes a first convolutional layer, a second convolutional layer, and an output layer;
the first convolution layer is used for extracting side information from the three-dimensional image information; the side information refers to the information of the side where the intersection line of the intersection planes in the three-dimensional image information of the target package is located.
The second convolutional layer is used for extracting end point information from the side information; the endpoint information refers to information of endpoints of each edge corresponding to the edge information.
The output layer is used for extracting a first endpoint coordinate, a second endpoint coordinate, a third endpoint coordinate, a fourth endpoint coordinate, a fifth endpoint coordinate and a sixth endpoint coordinate from the endpoint information, wherein the first endpoint coordinate and the second endpoint coordinate respectively represent endpoints with the maximum height coordinate and the minimum height coordinate, the third endpoint coordinate and the fourth endpoint coordinate respectively represent endpoints with the maximum width coordinate and the minimum width coordinate, and the fifth endpoint coordinate and the sixth endpoint coordinate respectively represent endpoints with the maximum length coordinate and the minimum length coordinate;
wherein the height coordinate, the width coordinate, and the length coordinate correspond to three spatial directions in the three-dimensional coordinate, respectively, for example, in the three-dimensional coordinate (x, y, z), z may be used to represent the coordinate in the height direction, x may represent the coordinate in the length direction, and y may represent the coordinate in the width direction.
In the embodiment of the invention, the convolutional neural network is utilized to extract six endpoint information in the three-dimensional image information, and the six endpoint information can represent the three-dimensional geometric shape of the target parcel. For example, the coordinate difference in the height direction of the first endpoint coordinate and the second endpoint coordinate reflects the maximum height of the target package, the coordinate difference in the width direction of the third endpoint coordinate and the fourth endpoint coordinate reflects the maximum width of the target package, and the coordinate difference in the length direction of the fifth endpoint coordinate and the sixth endpoint coordinate reflects the maximum length of the target package. And the maximum height, width and length of the target package reflects the maximum geometry of the target package. Thereby facilitating selection of a loading location for the target package that can accommodate the target package.
It should be noted that, in the present invention, by obtaining three-dimensional image information of a target parcel, extracting three-dimensional geometric features (a first endpoint coordinate, a second endpoint coordinate, a third endpoint coordinate, a fourth endpoint coordinate, a fifth endpoint coordinate, and a sixth endpoint coordinate) of the three-dimensional image information by using a convolutional neural network, representing a three-dimensional size of the target parcel by using the six three-dimensional coordinates, and further matching a suitable loading position for the target parcel, the present invention is applicable to parcels of different shapes, for example, parcels of non-standard cubic shapes can still be loaded by using an accommodating space matched by the six three-dimensional coordinates, and the problem in the prior art that the size of the parcel of non-standard cubic shapes is difficult to objectively describe is solved.
Optionally, before the inputting the three-dimensional image information into a preset feature extraction model to obtain the three-dimensional geometric feature of the target package, the method further includes:
obtaining a certain number of three-dimensional image samples to form a training set;
training the convolutional neural network by using the training set in a supervised learning mode;
and utilizing a gradient descent method to minimize a loss function to reversely adjust the weight parameters in the convolutional neural network layer by layer so as to improve the precision of the convolutional neural network.
In the embodiment of the invention, the convolutional neural network is trained in a supervised learning mode, and the parameters (convolutional kernels) of each convolutional layer of the convolutional neural network are determined. The method is favorable for improving the output precision of the convolutional neural network.
In step 103, receiving information of the target package is obtained, where the receiving information at least includes receiving address information.
In the embodiment of the invention, the delivery direction of the target package can be obtained by obtaining the receiving information of the target package and determining the receiving address, and further vehicles and other transportation tools driving to the delivery direction can be selected according to the delivery direction.
Optionally, the receiving information further includes a contact number of the recipient, and after the step 102, the method further includes:
calculating volume information of the target parcel based on the three-dimensional geometric features;
and sending the volume information to the contact number of the recipient.
In the embodiment of the invention, the volume information of the target package can be calculated by utilizing the extracted three-dimensional geometric characteristics, and the volume information of the target package is sent to the receiver of the target package, so that the receiver can timely know the volume of the package to be received, and the problem that the receiver is inconvenient to take and carry due to overlarge package volume is solved.
In step 104, a target vehicle for carrying the target package is determined based on the recipient address information.
In the embodiment of the invention, a plurality of transport means are respectively sent to different regions, the region to which the package is sent can be determined through the address receiving information, and then the target transport means capable of carrying the target package is determined.
In step 105, a loading location of the target package on the target vehicle is determined based on the three-dimensional geometric characteristics of the target package.
In the embodiment of the invention, the maximum volume of the target parcel is determined by extracting the three-dimensional geometric characteristics of the target parcel, and then the spatial position suitable for loading the target parcel can be selected on the transport tool.
Optionally, the step 105 may include:
acquiring three-dimensional geometrical characteristics of loading spaces of each wrapped loading pane arranged on the target transport tool;
selecting a target parcel loading pane matched with the three-dimensional geometric characteristics of the target parcel from the three-dimensional geometric characteristics of the loading space of each parcel loading pane;
determining the target package loading pane as a loading location of the target package on the target transport.
In the embodiment of the invention, a plurality of parcel loading panes for loading parcels are arranged on each logistics transport tool, and the size and the three-dimensional geometrical characteristics of each parcel loading pane on each logistics transport tool can be acquired in advance. Here, the three-dimensional geometrical feature of the parcel loading pane refers to the three-dimensional geometrical feature of its accommodation space, and may include a maximum height, a maximum length, and a maximum width that can be accommodated. By matching the three-dimensional geometry of the target package with the three-dimensional geometry of each package loading pane, a target package loading pane matching the three-dimensional geometry of the target package may be selected and determined as the loading location of the target package on the target transport.
The invention can reasonably distribute the loading positions matched with the sizes and the shapes of the packages with different sizes and shapes, and is beneficial to realizing the automatic loading of the logistics package sorting and the reasonable utilization of the loading space.
