Description

  The present invention relates to an information processing apparatus, an information processing system, an information processing program, and a recording medium for measuring the dimensions of a measuring object.

  In recent years, with the spread of online shopping and the like, the amount of baggage handled in delivery services such as home delivery has increased. Conventionally, it has been necessary to manually measure dimensions in order to determine a delivery fee for a package to be delivered. For this reason, the human cost is high and the processing efficiency in the delivery business is not good.

  There is a demand to perform delivery work efficiently by minimizing this manual work. In order to meet this demand, a portable information processing device that takes a two-dimensional image of a baggage, performs image processing on the two-dimensional image, calculates a three-dimensional size of the baggage, and determines a delivery fee based on the three-dimensional size Is known (see, for example, Patent Document 1).

JP 2003-303222 A

  However, in the method of calculating the size of the load from the two-dimensional image, it is necessary to photograph the load from two different angles in order to calculate the size. This photographing work is a troublesome work for the operator.

  In addition, the process of calculating dimensions using two two-dimensional images has a large processing load and requires a long processing time. Therefore, it is difficult to realize this calculation process with a portable information processing apparatus. In particular, a portable information processing apparatus used in a delivery service site is desired to be lightweight and have low power consumption, but it is difficult to meet those demands when processing a heavy load. .

  A method for calculating the size of a package from one two-dimensional image (for example, a ballot method) is also known. However, in order to calculate three-dimensional information from a two-dimensional image that originally has only two-dimensional information, complicated and time-consuming processes such as graphic development and rotation are required. Therefore, these methods are also difficult to realize in a portable information processing apparatus. Furthermore, even if the requirements for light weight and low power consumption are satisfied, the size calculated from one two-dimensional image that originally does not have information in the depth direction may be accompanied by a large error.

  Also known is a method for calculating the size of a package based on the size of a slip attached to the package. However, in this method, the measurement error of the dimension is large, and when the delivery fee is calculated based on the calculated dimension, the error exceeds the limit allowable in the actual delivery service. If the size is calculated too small, a loss occurs in the delivery company, and if the size is calculated excessively, a loss occurs in the sender of the package. Such losses exceed business acceptable limits, and this method has not reached a practical level.

A delivery fee calculating step for calculating a delivery fee for the measuring object.

  Also with this configuration, since the distance image of the measuring object is generated using only one distance image obtained by the distance image sensor, the measurement can be performed with low load and high accuracy.

The power supply unit 25 is a power supply for the handy terminal 100, receives power supply from the battery 26, and supplies power to each part of the handy terminal 100 including the CPU 11. The CPU 11 can control the power supply unit 25 to supply or stop power supply to a part or all of the circuits constituting the handy terminal 100.

  The display unit 27 has a function of controlling display on the display panel 111 illustrated in FIG.

The RAM 34 is a memory used for temporarily storing processing data generated in the middle of arithmetic processing or the like accompanying the operation of the handy terminal 100.

  FIG. 4 is a diagram showing the configuration of the distance image sensor block 30. As shown in FIG. The distance image sensor block 30 generates a distance image by the TOF (Time Of Flight) method. The distance image sensor block 30 includes an LED light emitting element unit 51, a light emitting / receiving driver unit 52, a light receiving optical system 53, a CCD light receiving shutter processing unit 54, a timing generation unit 55, and an A / D conversion unit 56. ing. The LED light emitting element 51 emits LED light toward the measuring object T. The timing and period of this light emission are controlled by the light emission drive signal generated by the timing generation unit 55. The light emission / reception driver unit 52 receives the light emission drive signal from the timing generation unit 55 and drives the LED light emitting element unit 51 according to the light emission drive signal.

  The light receiving optical system 53 receives light emitted from the LED light emitting element unit 51 and reflected from the measuring object T. The CCD light receiving shutter processing unit 54 converts the light received by the light receiving optical system 53 into an electrical signal by the CCD. At this time, the timing and period of photoelectric conversion by the electronic shutter, that is, the CCD, are controlled by an electronic shutter window signal generated by the timing generation unit 55. The light emission / reception driver unit 52 receives the electronic shutter window signal from the timing generation unit 55 and drives the CCD light reception shutter processing unit 54 in accordance with the electronic shutter window signal. Here, the electronic shutter is, for example, a CCD global shutter, an optical shutter, or the like, but is not limited thereto.

  FIG. 5 is a timing chart for explaining generation of a distance image by the distance image sensor block 30. As shown in FIG. 5, the light emission drive signal is a pulse wave, and is repeatedly driven (HIGH: light emission) and stopped (LOW: extinguished) at a constant cycle. Note that the actual amount of light emitted from the LED does not rise and fall according to the light emission drive signal, but rises and falls smoothly. The electronic shutter window signal is a pulse wave, and is repeatedly driven (HIGH) and stopped (LOW) at the same cycle as the light emission drive signal. The phase of the light emission drive signal and the electronic shutter window signal may be the same, and the phase may be slightly shifted (the electronic shutter window signal may be slightly delayed from the light emission drive signal).

  By driving the LED light emitting element unit 51 and the CCD light receiving shutter processing unit 54 with such a light emission driving signal and an electronic shutter window signal, a CCD light receiving amount as shown in FIG. 5 is obtained. Here, in each pixel, when the time until the reflected light is received by the CCD is long, that is, when the distance of the subject portion captured by the pixel is far from the information processing, the electronic shutter window signal The amount of reflected light that can be received by the CCD during the rising period is small. On the contrary, when the time until the reflected light is received by the CCD is short in each pixel, that is, when the distance of the subject portion captured by the pixel is close to the information processing, the electronic shutter window signal The amount of reflected light that can be received by the CCD during the rising period increases.

  Therefore, the distance of the subject portion captured by each pixel can be measured by the magnitude of the integrated value of the amount of light received while the light receiving shutter window signal rises in each pixel of the CCD (that is, the luminance value of each pixel). it can. In the CCD, since this light quantity integral value is converted into an electric signal, this electric signal indicates the distance of the subject portion captured by each pixel for each pixel. In this sense, the luminance value of each pixel is distance information indicating a distance. The CCD light receiving shutter processing unit 54 outputs the luminance values of all the pixels as a distance image. When a distance image is displayed, a pixel with a longer distance is displayed as a gray image having a lower density. In addition, you may make it display as a light-and-dark image with a density | concentration that a pixel is nearer.

  As shown in FIG. 5, the light emission by the LED light emitting element 51 and the photoelectric conversion (integration of the amount of received light) by the CCD light receiving shutter processing unit 54 may be performed a plurality of times in order to generate one distance image. In this case, the brightness value of each pixel for generating the distance image may be obtained by averaging the brightness values obtained by a plurality of times of light emission and light reception and / or adopting an intermediate value.

  Of the configuration of the distance image sensor block 30 shown in FIG. 5, the configuration excluding the LED light emitting element 51 and the light receiving optical system 53 corresponds to the distance image sensor, and the distance image sensor block 30 is included in the distance image generation unit of the present invention. Equivalent to.

  Returning to FIG. 4, the A / D conversion unit 56 converts the electrical signal (analog signal) output from the CCD light receiving shutter processing unit 54 into a digital signal, and outputs a distance image as a digital signal. This distance image is information in which the distance of the subject portion captured by each pixel is defined for every pixel.

  The user takes a distance image by operating the input key 112 with the back surface of the handy terminal 100 facing the measuring object T. A distance image is displayed on the display panel 111 in the preview state, and in this state, the user performs an operation for photographing the distance image with respect to the input key 112, thereby outputting a distance image used for calculating a dimension or the like. May be. The user shoots a distance image of the measuring object at an angle such that the entire measuring object that is a rectangular parallelepiped fits in the image and the three surfaces can be seen.

  FIG. 1 is a diagram illustrating a configuration of a dimension delivery fee calculation unit. The configuration and function of the dimension delivery fee calculation unit 60 are realized by the CPU 11 executing a program stored in the flash ROM 33 and executing arithmetic processing using the RAM 34. The size delivery fee calculation unit 60 calculates the size and the delivery fee using the distance image. The dimension delivery fee calculation unit 60 includes a measuring object region detection unit 61, a side / vertex detection unit 62, a coordinate conversion / side length calculation unit 63, a luminance value / distance conversion table unit 64, and a delivery fee calculation unit. 65 and a dimension delivery fee table 66.

  The distance image generated by the distance image sensor block 30 is input to the dimension delivery fee calculation unit 60. The measuring object region detection unit 61 detects the region of the measuring object from the input distance image. The side / vertex detection unit 62 detects sides and vertices from the measurement target region detected by the measurement target region detection unit 61. Here, the side can be detected by detecting the edge of the distance image, and the vertex can be detected by obtaining the intersection of the sides detected as the edge.

  In particular, the side / vertex detection unit 62 detects a vertex closest to the information processing apparatus, and detects three adjacent vertices on a common side with the vertex. FIG. 6 is a diagram illustrating an example of sides and vertices detected from a distance image. The distance image has pixel position and distance information for each pixel. This distance image is information on the three-dimensional shape of the measuring object in the distance image space. This three-dimensional shape information is expressed in the viewpoint reference coordinate system (xyz coordinates in FIG. 6). The closest vertex is the point A, and the three adjacent vertices are the point B, the point C, and the point D. The side / vertex detection unit 62 detects a vertex A, a vertex B, a vertex C, a vertex D, a side AB, a side AC, and a side AD. Here, the vertex A is not limited to the vertex closest to the information processing apparatus. However, by setting the vertex closest to the vertex, the SNR (signal-to-noise ratio) of the reflected light received by the CCD is high, Detection error can be reduced.

  The coordinate transformation / side length calculation unit 63 inputs the information of the sides and vertices detected by the side / vertex detection unit 62 and the distance image generated by the distance image sensor block 30, and inputs the sides and distances in the distance image. Transform vertices. As described above, since the distance information of each pixel in the distance image is obtained as an integrated value (luminance value) of the amount of light received by the CCD, the coordinate conversion / side length calculation unit 63 first calculates the luminance value of the vertex. Is converted to distance. For this purpose, the coordinate conversion / side length calculation unit 63 refers to the luminance value / distance conversion table stored in the luminance value / distance conversion table unit 64 and converts the luminance value into a distance. Then, the distance image has three-dimensional information including the pixel position (two-dimensional) in the viewpoint reference coordinate system and the distance for each image.

  The coordinate conversion / side length calculation unit 63 performs unit conversion and rotation conversion, specifically affine conversion, on the information on the pixel position of the vertex and the distance thereof. The coordinate transformation / side length calculation unit 63 uses the vertex having the shortest distance as the origin, the direction of the side AB as the depth direction (D), the side AC as the width direction (W), and the side AD as the height direction ( H) is converted into a package coordinate system (DWH coordinates in FIG. 6).

Specifically, the coordinate conversion / side length calculation unit 63 performs coordinate conversion as follows. The pixel positions and distance information (distance information converted from luminance values) of the vertices A, B, C, and D are expressed as A = (A _X , A _Y , A _Z ), B = (B _X , B _Y , B _Z). ), C = (C _X , C _Y , C _Z ), D = (D _X , D _Y , D _Z ). Here, A _X , B _X , C _X , and D _X are the x coordinate values in the viewpoint reference coordinate system of each vertex, and A _Y , B _Y , C _Y , and D _Y are the viewpoint reference coordinates of each vertex. Y z values in the system, and A _Z , B _Z , C _Z and D _Z are distance values (z coordinate values) in the viewpoint reference coordinate system of each vertex.

上記の式によって得られる（Ｂ_D，０，０）、（０，Ｃ_W，０）、（０，０，Ｄ_H）は、それぞれ頂点Ａを原点とする荷物座標系（現実空間）における頂点Ｂ、頂点Ｃ、頂点Ｄの座標であり、Ｂ_D、Ｃ_W、Ｄ_Hは、それぞれ現実空間における辺ＡＢ、辺ＡＣ、辺ＡＤの長さである。なお、座標変換・辺長さ計算部６３は、本発明の採寸処理部に相当する。 The coordinate conversion / side length calculation unit 63 converts these four vertices according to the following expression.

(B _D , 0, 0), (0, C _W , 0), and (0, 0, D _H ) obtained by the above formulas are vertices in the luggage coordinate system (real space) with the vertex A as the origin. The coordinates of B, vertex C, and vertex D, and B _D , C _W , and D _H are the lengths of side AB, side AC, and side AD, respectively, in the real space. The coordinate conversion / side length calculation unit 63 corresponds to the measurement processing unit of the present invention.

The delivery fee calculation unit 65 calculates a delivery fee based on the lengths B _D , C _W , and _DH of the side AB, the side AC, and the side AD. In the present embodiment, the delivery fee calculation unit 65 calculates the delivery fee based on the total length B _D + C _W + _DH of the sides AB, AC, and AD. The dimension delivery fee table section 66 stores a dimension delivery fee table in which delivery fees corresponding to the total length B _D + C _W + _DH are defined. Note that B _D × C _W × _DH may be the dimension of the object to be measured.

The delivery fee calculation unit 65 refers to this size delivery fee table and obtains a delivery fee corresponding to the total length B _D + C _W + _DH . At this time, the delivery fee calculation unit 65 calculates the delivery fee based on the package / delivery information including the package weight, the delivery source, the delivery destination, the delivery designated time, and the delivery management temperature (room temperature, refrigeration, frozen). It's okay. This package / delivery information may be acquired by reading the barcode attached to the package with the barcode scanner unit 32, or may be acquired by the user using an input key. The delivery fee calculation unit 65 outputs information on the lengths B _D , C _W , _DH of the sides AB, AC, AD and the delivery fee.

  FIG. 7 is a diagram illustrating a display example of a screen displayed on the display panel 111 of the handy terminal 100 after the delivery fee is calculated by the delivery fee calculation unit 65. On the display panel 111, three sides and four vertices detected by the side / vertex detection unit 62 are superimposed on the photographed baggage image, and the length of each side is displayed. . Further, the total length of each side is expressed as a size, and the weight, classification (S, M, L, etc.), and the charge of the package are described. Here, the classification is determined by classifying based on the size and weight of the luggage. Note that the display of the screen is not limited to displaying these information after the dimensions of the measuring object are calculated. For example, each time the processing result is obtained, the image of the package, the side / vertex, the side length, the classification You may display them on the screen one after another in the order of charges.

  FIG. 8 is a flowchart of measurement and delivery fee calculation in the handy terminal 100. The user directs the back of the handy terminal 100 to the object to be measured (see FIG. 2) and instructs to take a distance image (step S81). The LED light emitting element 51 emits pulsed light by driving the LED light emitting element unit 51 with a predetermined pulse width (step S82), and the CCD light receiving shutter processing unit 54 has a predetermined timing at a predetermined timing synchronized with the pulsed light. By driving the light receiving element of the CCD with the pulse width, a signal having a luminance value corresponding to the integrated value of the amount of received light including the pulsed light is generated (step S83). The A / D conversion unit 56 digitally converts the luminance value and generates a distance image using the luminance value as distance information (step S84).

  The measuring object region detecting unit 61 detects the measuring object region from the distance image (step S85), and the side / vertex detecting unit 62 detects the vertexes closest to the distance and the three vertices adjacent thereto from the measuring object region. , And the three sides connecting the nearest vertex and the three adjacent vertices (four vertices in total) are detected (step S86). The coordinate conversion / side length calculation unit 63 first converts the distance information obtained as the luminance value into the distance unit for the vertices detected by the side / vertex detection unit 62, and then converts the distance information 4 into the distance unit. The coordinates of the two vertices are transformed into the luggage coordinate system with the closest vertex as a reference, and the lengths of the three sides in the real space are obtained (step S87).

  The delivery fee calculation unit 65 calculates a delivery fee based on the lengths of the three sides calculated by the coordinate side / side length calculation unit 63 and other package / delivery information as necessary (step). S88).

  Next, an information processing system including the above information processing apparatus will be described. Here, an example in which the measuring object is a luggage will be described. The information processing system 500 according to the embodiment of the present invention is a system that associates information for specifying a package with information on the size of the package. FIG. 9 is a diagram showing a configuration of the information processing system according to the embodiment of this invention. The information processing system 500 includes an information processing apparatus (handy terminal) 100 and a host 200. Various types of information can be transmitted from the information processing apparatus 100 to the host 200 by wireless communication. The host 200 can communicate information with a package management system (not shown).

  The information processing apparatus 100 uses the barcode scanner unit 32 to acquire information (package ID) that identifies the package from the barcode written on the package. Moreover, the dimension of a measuring object is measured by said structure and operation | movement. Then, the information processing apparatus 100 associates the information specifying the package with the information on the size of the package and transmits the information to the host 200 wirelessly. The host 200 transmits the associated information to the package management system, so that the package management system can obtain information about which package is which size, and manages the package based on the information. be able to. The package / delivery information may be read from the bar code, and the package / delivery information may be transmitted to the host 200 in association with the package ID and size information. Also, instead of or in addition to the package size information, package delivery information may be associated.

  As a modification, the association of these pieces of information may be performed by the host 200. In this case, the host 200 associates information specifying the package, information on the size of the package, and other information to be associated such as package / delivery information transmitted from the same information processing apparatus 100. Even in this case, the package management system can obtain information on which package is which size, and can manage the package based on the information.

  As described above, according to the information processing apparatus (handy terminal) of the present embodiment, information on the three-dimensional shape of a measurement object (for example, a package to be delivered) is acquired and measurement is performed. The dimension of the measuring object can be measured with high accuracy. As described above, since the calculation processing load is small, the power consumption is small, and the present invention is suitably applied to a portable information processing apparatus. In addition, since the TOF method is used to acquire the three-dimensional information, it is not necessary to change the position or angle, and it is convenient to perform measurement with high accuracy.

  Since the present invention generates a distance image of a measuring object using only one distance image obtained by the distance image sensor, the distance image is generated with low load and high accuracy, and the measurement object is measured. It has the effect of being able to calculate the delivery charge based on it, and is useful as an information processing device or the like.
