Input media 14 is made up of keyboard etc., the command signal of the operational symbol reflecting operation image processing apparatus 100 is exported to CPU10.
Below with according to image procossing (the employing image processing apparatus 100) result of measuring object size and the generation of dimension information and the example using the dimension information generated, the three-dimensional size of specific solid object thing is described and obtains the operation of three-dimensional shape data.
Fig. 2 A is an example of the solid object thing that image processing apparatus 100 (with reference to figure 1) is taken.Herein as shown in the figure, the solid object thing CO as reference object is buildings, and handling object image is the multiple parts of images after all Image Segmentation Usings obtained from shooting solid object thing CO.In addition, as shown in fig. 2 a-2d, define X-direction, Y-direction and Z-direction, make the front of buildings become the face being parallel to XY face.
As shown in Figure 2 A, the engineer's scale SC of rectilinear form has been sticked on each several part surface of solid object thing CO.Engineer's scale SC is accompanied with known scale, as the standard measuring solid object thing each several part size.In other words, the memory storage 12 of image processing apparatus 100 saves the calibration information of engineer's scale SC, by the scale of reading images medium scale, can grasp the physical size of the image be taken.In particular, memory storage 12 not only saves the calibration information of engineer's scale SC, also saving the various information such as shape and size of engineer's scale SC, the various programs etc. of the frontal information that can obtain object images can be preserved further according to the relevant information of engineer's scale SC in advance.CPU10 suitably reads information from memory storage 12 or program, by catching the size and Orientation of shooting image medium scale SC, on the basis of frontal that determined solid object thing CO surface, for each several part of the image on the solid object thing CO surface of the subsidiary engineer's scale SC of shooting, the measurement of size can be carried out according to the engineer's scale SC containing surface direction and depth direction.In addition, CPU10 also can go out the length of solid object thing CO, area or volume according to the Size calculation measured.
The operation below illustrating shooting and the scale number of the engineer's scale SC part of the data of image that is taken according to and the extraction etc. of object data of measuring object part.First, the solid object thing CO of position (angle and scope) as shown in Figure 2 A taken by camera head 11 (with reference to figure 1), obtains overall image.Then, for carrying out the process of dimensional measurement by the solid object thing CO view data obtained, the segmentation of multiple parts of images is carried out by CPU10 (with reference to figure 1).As the solid object thing CO image taken in Fig. 2 A, CPU10 judges according to view data, border when the crest line RD of the outline portion of buildings solid object thing CO is split respectively as parts of images, along crest line RD, the front portion image OG1 of solid object thing CO, lateral parts image OG2 and top section image OG3 these three part is separated and splits.Also namely, the dividing processing of this image, is judged crest line RD by CPU10, can automatically carry out.By above process, split the lateral parts image OG2 as shown in Figure 2 B shown in front portion image OG1 and Fig. 2 C.Now, front portion image OG1, the lateral parts image OG2 of segmentation comprise an engineer's scale SC at least respectively.In front portion image OG1 as shown in Figure 2 B, two engineer's scale SC are attached.Accordingly, namely front portion image OG1 and lateral parts image OG2 can carry out dimensional measurement as respective measurement standard by engineer's scale SC.Further, as required, also can split further each several part image.In order to measure size, the image of segmentation all at least must comprise more than one engineer's scale SC.
In order to image can be split under the state comprising above engineer's scale SC, whether the CPU10 of image processing apparatus 100 reads the geomery of engineer's scale SC from the memory storage 12 saving data in advance, judged in the parts of images split containing engineer's scale SC together when dividing processing by pattern-recognition.
The treatment step of the dimension measurement of a parts of images is described below with reference to Fig. 2 B.Prerequisite is, as in the front portion image OG1 of object, there are two measurement standards, i.e. two engineer's scale SC.Now, both can as the standard of dimensional measurement, and, can by the front of these two engineer's scale SC determining section image OG1.As mentioned above, the memory storage 12 of image processing apparatus 100 prestores the relevant information measuring component engineer's scale SC, in the information stored, according to information such as the shapes that engineer's scale SC frontal is relevant, calculate crooked (distortion) situation of in esse two engineer's scale SC in the image OG1 of front portion, and judging this inclination attitude as which kind of degree according to result of calculation, the state seen from frontal needs the correction of which kind of degree.And can according to this result of calculation, judge front portion image OG1 just facing to.In addition, the front portion image OG1 shown in Fig. 2 B is the image from front shooting a little before segmentation, and two engineer's scale SC's is crooked smaller, and necessary correction amount is also less.Lateral parts image OG2 shown in Fig. 2 C of face is not from front shooting, and two engineer's scale SC's on it is crooked comparatively large, and necessary correction amount is also more.In addition, namely the front portion image OG1, the lateral parts image OG2 that judge based on engineer's scale SC and the inclination conditions of top section image OG3 judge that the concrete grammar of frontal has a lot, enumerating an example herein, by judging the direction comprising the normal line vector in the face of image, judging frontal.Specifically, as shown in Fig. 2 A etc., front portion image OG1, when taking in advance, two engineer's scale SC are attached in the face of front portion image OG1, make its orthogonal directions as longer direction, using these directions as standard, the normal line vector that the specific plane going out to comprise parts of images OG1 is relative, the direction of alignment amount in this way, can determine the frontal of front portion image OG1.As Fig. 2 B, 2C, other lateral parts image OG2 and top section image OG3 too can according to orthogonal two engineer's scale SC its frontal specific of longer direction in face.In addition, the Z-direction in Fig. 2 B is the direction of normal line vector, and the X-direction in Fig. 2 C is the direction of normal line vector.
Get back to Fig. 2 B, as above for the front portion image OG1 determining frontal, the size of each several part can be measured according to two engineer's scale SC.Concrete measuring method is as follows.Consider the value after adopting the result of carrying out measuring respectively according to each engineer's scale SC to be weighted.Usually, the picture size based on engineer's scale SC can correct measurement and the part of prediction near engineer's scale SC position.Therefore, for each several part of image, by the size value selecting relatively near engineer's scale SC to measure, more correctly dimensional measurement can be carried out.As shown in Figure 2 B, in image range, the object of process and all scopes, that is, the scope of measurement size is answered, as the whole front of solid object thing CO, namely, whole front portion image OG1, carries out the weighting corresponding with the measurement result of two engineer's scale SC, as dimensional data and dimension information according to each several part on image with two engineer's scale SC distance situation on image.As shown in Figure 2 B in image, list measure size object as window portion WP and door portion DP.As diagram, wherein the engineer's scale SC on the left side is relatively near for the position of window portion WP, and the engineer's scale SC on the right is relatively far away for the position of window portion WP.Now, the size of the window portion WP finally obtained reflects the size measured based on left side engineer's scale SC more strongly.And the range difference of the engineer's scale SC on door portion DP and left side engineer's scale SC and the right is few, in this case, the size of the door portion DP finally obtained is the value obtained after being averaged to the size measured based on two engineer's scale SC.In addition, be contained in each several part of front portion image OG1, when the object carrying out dimensional measurement is only window portion WP or door portion DP, can will comprise the first image-region Z1 of the engineer's scale SC pasted near window portion WP and window portion WP as handling object, or will the second image-region Z2 of the engineer's scale SC pasted near a portion DP and door portion DP be comprised as handling object.If there is the partial objects image at least comprising an engineer's scale SC, then dimensional measurement can be carried out.
About the situation of above Fig. 2 B, in the multiple parts of images split from Fig. 2 A, using direct picture or slightly front portion image OG1 as the object of measurement processing, in order to the correction become needed for the state facing comparatively frontal is less, but as shown in Figure 2 C, in Fig. 2 A segmentation not from front but the face taken from the side and lateral parts image OG2 time, lateral parts image OG2 becomes the image of tilted direction depth, to the corresponding part of lateral parts image OG2 correction of Fig. 2 C, for obtaining the status image seen from front as shown in Figure 2 D, need the correction that quite a few is measured.Especially, when the image of shooting is two dimension (plane) image, be therefore sometimes difficult to the size that correct measurement goes out the depth direction that lateral parts image OG2 tilts.On the other hand, the situation of the present embodiment, in Fig. 2 C, as two engineer's scale SC of dimensional measurement standard also towards depth Direction distortion, and takes in this condition.Therefore, by the engineer's scale SC of this heeling condition is carried out dimensional measurement as standard, even if the image of vergence direction as that shown in fig. 2 c, also comparatively correctly dimensional measurement can be carried out.Now, according to occasion, utilize the orthogonal of two engineer's scale SC to intersect, direction and the frontal of the normal line vector in the face comprising lateral parts image OG2 can be determined.And relative weighting is carried out to the measurement result of multiple engineer's scale SC, result can be used as dimensional data and dimension information.Even can be as shown in Figure 2 C, if the rectangular embedded window FW of measuring object, the size of the part then measuring embedded window FW respectively and third and fourth image-region X1, X2 of comprising at least one engineer's scale SC, by stitching measure result, the size of an embedded window FW of rectangle also can be measured.Specifically, first, using in Fig. 2 C as the scale of the engineer's scale SC of standard and inclination conditions as standard, carry out the dimensional measurement of each several parts such as embedded window FW, generate length and the area equidimension information of each several parts such as the embedded window FW forming lateral parts image OG2.Now, also detect the inclination conditions of the lateral parts image OG2 of state shown in Fig. 2 C, calculate necessary correction amount.By above step, based on the dimension information generated and the correction amount of necessity, by reconstituting the image of lateral parts image OG2 towards frontal state, image as shown in Figure 2 D can be formed.In addition, reconstituting of image as shown in Figure 2 D, also can be the state of the parts of images eliminating engineer's scale SC.
The information of front and X-direction and Y-direction relative dimensions can be obtained in Fig. 2 B, the information of side and Y-direction and Z-direction relative dimensions in Fig. 2 C, can be obtained.Further, by the dimension information in spliced map 2B and Fig. 2 C, the information of X-direction, Y-direction and Z-direction relative dimensions can be obtained.Use these information, a part of data of the three-dimensional shape of specific solid object thing CO can be obtained.That is, by these dimension informations comprehensive, the data of three-dimensional shape can be constructed.
Referring to the process flow diagram of the data genaration operation of Fig. 3, illustrate and obtain dimension information and the step based on the dimension information data acquisition three-dimensional shape data obtained.
First, the view data receiving element 11a of image processing apparatus 100 receives the view data (step S1) of the solid object thing CO as reference object as above taken by camera head 11.Then, the object images such as the view data auto Segmentation front portion image OG1 of the solid object thing CO that the CPU10 of image processing apparatus 100 receives from view data receiving element 11a, and obtain view data, wherein contain the object data (step S2) as dimensional measurement object.Then, the view data split from step S2, the scale number certificate that withdrawal ratio chi SC is relevant respectively and object data (step S3).Such as, for scale number certificate, determine the kind of engineer's scale SC and identify the unit and outer shape etc. of scale, for object data, from the shape of Iamge Segmentation as object part, and determining object range.Such as determine from front portion image OG1 to window portion WP and door portion DP.In addition, about the determination of this object, according to presetting, automatically can be carried out by CPU10, also can get involved operational symbol, namely judge the specific of object by naked eyes.Then the object data (step S4) extracted in analytical procedure S3.Specifically, the object data of scale number according to correspondence of extraction can be contrasted, and based on the scale number certificate of special object partial shape etc., measure the size of each object data.As mentioned above, dimension information is generated according to the lateral parts image OG2 of Fig. 2 C.Therefore, dimension information data are obtained from plane description image.Further, supplemental image data can be carried out according to the dimension information obtained.Also namely, based on dimension information and the correction amount of parts of images OG2 generation from the side, the direct picture (as shown in Figure 2 D) of correction can be generated, the image that such as display device 13 (with reference to figure 1) shows.Then, CPU10 repeatedly carries out the operating procedure (step S5:No) of above-mentioned S3 ~ S4 several times.Such as shown in Fig. 2 A, when segmentation front portion image OG1, lateral parts image OG2, top section image OG3 these three, Water demand each several part image, at least needs the operation repeating more than 3 times.In step s 5, at the end of judging all data analyses (step S5:Yes), the dimension information that CPU10 comprehensively gets, generates the three-dimensional shape data can determining three-dimensional shape, and the data of generation is kept at memory storage 12 li (step S6).In addition, memory storage 12 also saves the dimension information of each several part got from the operation of the step S1 repeatedly carried out as required ~ S4.Now, the view data of each image and the length of each several part corresponding with it and the dimension information of inclination conditions become a set of information.Also namely, the size that pixel count is corresponding to inclination conditions can convert.Therefore, each several part size of each image can directly be calculated.
As mentioned above, in the image processing apparatus 100 relevant with the present embodiment, the camera head 11 as image unit is together taken as the engineer's scale SC measuring component with the solid object thing CO of subsidiary size.CPU10 takes according to camera head 11 and about the scale number certificate of engineer's scale SC information in the view data received by view data receiving element 11a, by measuring object data, can get the just size of object part.Therefore, when carrying out the reconstruction of buildings, the description image that can get according to camera head 11, easy and correctly obtain the data in required reconstruction place.Further, also stereo-picture can be demonstrated according to the three-dimensional shape data generated in step S6.
As mentioned above, when the dimension information based on multiple Computer image genration solid object thing CO, in order to carry out comprehensively using the scale of known proportion chi SC as the data of absolute criterion to during measurement, even if the projection distance between each image during image projection is different, physics as shooting state varies in size, and can unified integration be also a dimension information.
In addition, can also get up by dimension information with based on each several part link of the image of dimension information acquisition.Again in the direct picture constructed as shown in Figure 2 D, a part for the image of the picture photographs of display device 13 (with reference to figure 1) can carry out Region specification according to the instruction of the operational symbol having got involved input media 14, and calculates according to dimension information and demonstrate the length and area etc. of the scope of having carried out Region specification.
Further, can also generate according to the dimension information of each several part the three-dimensional shape data can determining 3D shape.That is, CPU10 the plane picture taken according to the size of solid object thing CO, can be converted to the information that three-dimensional shape is relevant.Therefore, image processing apparatus 100 can be easy and correctly get the relevant data of the size of solid object thing CO.
When the image of the solid object thing CO taken from the position (angle and scope) shown in Fig. 2 A combines with the image of the solid object thing CO taken from other positions (angle and scope), sometimes, for the shooting distance of solid object thing CO or the focal length multiplying power difference of camera head 11, the engineer's scale disunity of the description image namely taken.And in the present embodiment, the scale of the engineer's scale SC incidentally taken by each description image, as benchmark, is measured respectively, the dimension information obtained matches each other, and is correct full size.
In the present embodiment, in each several part image of front portion image OG1, the direction of the normal line vector determined by two crossing engineer's scale SC orthogonal in plane, as the frontal of each several part image, then can be comparatively easy and correctly determine the frontal of parts of images, but, the method for the frontal of determining section image has more than and is limited to this one.Such as, alternatively, if the inclined degree of an engineer's scale SC correctly can be obtained, then can based on the program of inclined degree calculating this engineer's scale SC, thus the frontal of determining section image.When using two or more engineer's scale SC, if the direction of the normal line vector of expressed portion partial image frontal can be determined, be not then necessarily configured to orthogonal crossing engineer's scale.And, above step determines by normal line vector the plane comprising parts of images, when the surface of the solid object thing CO as object is curved surface, in corresponding image, if ask for normal line vector at multiple point, the surface curvature of the solid object thing CO as object also can be determined.
In the present embodiment, the front portion image OG1 divided by crest line RD, lateral parts image OG2, top section image OG3 all only obtain dimension information by the engineer's scale comprised in each image, also the engineer's scale exceeding crest line RD and divide scope can be adopted as the part of benchmark.As shown in Figure 4, when the upper area Z3 of front portion image OG1 is as measuring object, except the engineer's scale SC comprised in the image OG1 of front portion, be arranged in top section image OG3 and also can add as benchmark when measuring this upper area Z3 apart from the engineer's scale SC of the upper area Z3 closer location of front portion image OG1.
In addition, the method for weighting also has multiple, as mentioned above, when being weighted according to the distance from the position of object to engineer's scale, manually can determine the degree of weighting, such as, be inversely proportional to distance or be inversely proportional to 2 times of distance.
