However, after obtaining the bitmap data compressed in a lossless compression format such as ZIP, the two-dimensional image data that is the original bitmap data is obtained. You may make it extend | expand to. 2D image data in bitmap format is obtained by acquiring compressed data in an image compression format such as JPEG (Joint Photographic Experts Group), GIF (Graphics Interchange Format), or TIFF (Tagged Image File Format). You may make it convert into. Furthermore, vector data may be acquired and converted into two-dimensional image data in a bitmap format. The predetermined recording position in step S102 is a recording area in the recording unit 12 indicated as a folder path. Note that a predetermined recording position may be set on an external device or another recording medium.

  Then, the image generation apparatus 1 outputs an input screen related to image generation from the output unit 15 which is a monitor under the control of the control unit 10 (S103).

  FIG. 3 is an explanatory diagram showing an input screen output from the output unit 15 of the image generation apparatus 1 according to Embodiment 1 of the present invention. On the input screen, a screen for setting input conditions is shown in the upper row, and a screen for setting output conditions is set in the lower row.

In the screen example shown in FIG. 3, one two-dimensional image data is designated for the first to third layers, but a plurality of two-dimensional image data is designated for the fourth layer. In addition, “test1.bmp” and “test2.bmp”, which are two-dimensional image data specified in the fourth layer, are also specified in the first and second layers.

By giving to each pixel, 2.5-dimensional image data is generated. For example, assuming a space defined by the X axis, the Y axis, and the Z axis that are orthogonal to each other, if the two-dimensional image indicated by the two-dimensional image data is shown on the XY plane, the thickness direction is the Z axis Direction. In the present application, the space in which the length in the thickness direction is defined as “thickness” is handled by the concept of “layer”. In addition, the order data input to the “layer” input field is handled as information indicating the arrangement order in which layers are stacked. The number of divisions entered in the input field for “number of divisions of layers” indicates the number when the layers are equally divided in the thickness direction. The length in the thickness direction divided based on the number of divisions is also used as a division unit when voxelization that is a constituent unit of a three-dimensional image is performed. In the material data shown in the material input column, a code indicating information on the material, material, surface state, etc. of the part corresponding to the 2.5-dimensional image data is input. In addition, data input to the folder path, layer, file name, layer thickness, number of divisions and material shown in the screen example of FIG. 3 is recorded in the image generation apparatus 1 as an associated record.

  The lower screen for setting the output condition shows the voxel folder path for outputting the generated 3D image data and voxel data. The voxel file name assigned to the generated 3D image data and voxel data, and the start point A coordinate range indicated by X, start point Y, end point X, and end point Y, and a division number for division into division units indicated by division number X and division number Y are shown. In the first embodiment, 1 is set in the area number item. However, in the third embodiment, which will be described later, the solid indicated by the plurality of three-dimensional image data is divided into a plurality of areas. Is inputted with a numerical value specifying each area.

  The operator operates the input unit 14 to input data in the input fields for items such as layer, file name, layer thickness, number of divisions, material, and output conditions.

  Returning to the flowchart, under the control of the control unit 10, the image generation apparatus 1 accepts each of order data indicating each arrangement order with respect to a plurality of acquired two-dimensional image data based on an operation using the input unit 14 (S <b> 104). ). The order data received in step S104 is data input in the “layer” input field.

  Furthermore, the image generation apparatus 1 receives specific data for specifying a plurality of acquired two-dimensional image data based on an operation using the input unit 14 under the control of the control unit 10 (S105). The specific data received in step S105 is data input in the “file name” input field, and is the name of the two-dimensional image data recorded at a predetermined recording position in step S102. That is, the two-dimensional image data used for generating the three-dimensional image data is designated by the specific data.

  Furthermore, the image generation apparatus 1 receives thickness data indicating the thicknesses of the plurality of acquired two-dimensional image data based on the operation using the input unit 14 under the control of the control unit 10 (S106). The thickness data received in step S106 is data input in the “layer thickness” input field.

  Furthermore, the image generation apparatus 1 receives the respective division number data for the plurality of acquired two-dimensional image data based on the operation using the input unit 14 under the control of the control unit 10 (S107). The division number data received in step S107 is data input in the “division number” input field.

  Furthermore, the image generation apparatus 1 receives the respective material data for the plurality of acquired two-dimensional image data based on the operation using the input unit 14 under the control of the control unit 10 (S108). The material data received in step S108 is data input in the “material” input field.

  Order data (layer), specific data (file name), thickness data (layer thickness), division number data (layer division number), material data (material) received by the image generation apparatus 1 through the processing of steps S104 to S108 ) And the like are managed as data in record units associated with each other. It should be noted that data other than the data described in steps S104 to S108 can also be set to receive input through similar processing.

  Furthermore, the image generation apparatus 1 receives an output condition related to data for the generated three-dimensional image data or the like based on an operation using the input unit 14 under the control of the control unit 10 (S109). The received output condition is managed in association with data related to the input condition.

  The image generation device 1 gives a thickness based on the thickness data to each pixel included in the two-dimensional image data with respect to a plurality of two-dimensional image data under the control of the control unit 10. Dimensional image data is generated (S110). In step S110, the length based on the thickness data associated with the specific data is given to each pixel as the thickness with respect to the two-dimensional image data specified by the received specific data. For example, assuming that a space defined by the X axis, the Y axis, and the Z axis that are orthogonal to each other is assumed, the process for giving a thickness to each pixel is a two-dimensional image represented by two-dimensional image data. This is a process of stacking each pixel of the two-dimensional image data by the number corresponding to the thickness in the thickness direction indicated by the Z axis orthogonal to the XY plane. Here, a coordinate system in which the XY plane and the Z axis are orthogonal is used, but the angle at which the XY plane and the Z axis intersect can be set to an arbitrary angle such as 45 degrees or 60 degrees. . Furthermore, a straight line passing through the XY plane on which the two-dimensional image indicated by the two-dimensional image data is arranged is set, and data indicating a solid based on the locus swung with the set straight line as a rocking axis is displayed as a 2.5-dimensional image. You may make it produce | generate as data. In this case, the thickness data is set to indicate values such as a swing angle and a movement distance at a predetermined distance from the swing axis. Further, data indicating a solid based on a trajectory rotated with a straight line passing through the XY plane as a rotation axis may be generated as 2.5-dimensional image data. In step S110, a process of generating 2.5D image data is performed on all 2D image data specified by the specified data that has received the input. In addition, when a plurality of designations are made for one two-dimensional image data, 2.5D image data generation processing to which each thickness is given is performed according to the designated number of times.

  The image generation device 1 generates three-dimensional image data by superimposing the generated plurality of 2.5-dimensional image data in the thickness direction in the arrangement order based on the order data under the control of the control unit 10 (S111). . The surface of the three-dimensional image indicated by the generated three-dimensional image data is subjected to rendering processing based on data indicating the material, material, surface state, etc. indicated by the accepted material data. In the rendering process, it is possible to designate the surface image data by previously storing the material data and the surface image data for rendering in the recording unit 12 in association with each other. The designated surface image data is pasted on the surface of the three-dimensional image data. The pasted surface image data is subjected to processing such as shading.

  Under the control of the control unit 10, the image generation device 1 analyzes the generated three-dimensional image data for each constituent unit of the three-dimensional image, thereby generating voxel data including the analysis result of each constituent unit (S112). ). The voxel data is data indicating data relating to an object indicated by a three-dimensional image such as a material and a part for each constituent unit of the three-dimensional image data. The data indicating the material of the voxel data is data based on the material data. The material data related to the structural unit of the surface of the object indicates at least one of the material, the material, and the surface state. The material and / or material is indicated in the material data related to the structural unit inside the object. Since the image generation apparatus 1 according to the present invention uses 3D image data generated based on 2D image data indicating a 2D image with a plurality of pixels such as bitmap data, for example, 3D configured by vector data is used. Compared with the case of analyzing the dimensional image data, the analysis processing for each structural unit is easy to execute, so that the processing load of the apparatus can be reduced and the processing time can be shortened.

  The image generation apparatus 1 outputs the generated three-dimensional image data and voxel data as a result of the three-dimensional image generation process under the control of the control unit 10 (S113). The output is processing such as display of an image from the output unit 15 and recording to the recording unit 12. The output process is executed based on the received output condition.
