Object size calculation system

The present invention relates to an object size calculation system, and more particularly to an object size calculation system capable of capturing a data and an image obtained by an object to be measured through two photographic lenses and calculating an actual size of the object to be tested.

Since a general photographed object can only capture an image, if the actual size of the object is to be calculated after the object is photographed, the conventional technique cannot be achieved. If the actual size of the object can be calculated via the photographed object, it can be applied to different photographs. The field will also add a lot of added value to the filming;

At present, there is an electronic vehicle with a dual photographic lens. This type of dual photographic lens is designed with two camera lenses with different focal lengths. The two camera lenses can be used in standard and distant modes, and can be used in two different ways. Switch between focal lengths. When the user takes a picture through the mobile phone, the device will simultaneously capture two different focal length photo images, and the technique of applying this dual photographic lens will be able to calculate the distance between the electronic vehicle and the object to be tested, and then proceed. Determining the proportion of the pixel of the object to be tested on the touch screen of the electronic vehicle, calculating the actual size of the object to be tested, and finally the distance between the electronic vehicle and the object to be tested and the to-be-tested The size of the pixels on the touch screen is combined to calculate the actual size of the object to be tested, which should be an optimal solution.

More specifically, the electronic carrier is a tablet, a driving recorder, a POS machine, a camera, a game machine, a television, a monitor, or an advertising machine.

More specifically, the touch screen of the electronic vehicle can also be a non-touch screen.

Other details, features, and advantages of the present invention will be apparent from the following description of the preferred embodiments.

Please refer to FIGS. 1A-1B, which are schematic diagrams showing the overall architecture of an electronic vehicle of the object size calculation system of the present invention and an architecture of the application program. As can be seen from the figure, the object size calculation system of the present invention has an electronic carrier 1. The electronic vehicle 1 has a first photographic lens 11 , a second photographic lens 12 and a touch screen 13 (which can be implemented instead of a non-touch screen), and the electronic carrier 1 is internally mounted. There is an application 14, and the electronic vehicle is a smart phone or a tablet;

The first photographic lens 11 and the second photographic lens 12 can capture an image file for an object 2 to be tested, and the application 14 is configured to measure the size of at least one object 2 to be tested. At least one object distance calculation module 141, an image ratio determination module 142 and an item size calculation module 143;

As shown in FIG. 2A and FIG. 2B , the object distance calculation module 141 can calculate an angle θ1 and θ2 between the first photographic lens 11 and the second photographic lens 12 and the object 2 to be measured by an algorithm, and then The fixed distance A (known distance) between the first photographic lens 11 and the second photographic lens 12 is used to know the distance B between the object 2 to be measured and the first photographic lens 11 and the object to be tested. 2, the distance C from the second photographic lens 12, and then calculate the actual distance D between the electronic carrier 1 and the object 2 to be tested, wherein the A/2 and B and A/2 and C are trigonometric functions. The algorithm compares the actual distance D between the object 2 to be tested and the electronic carrier 1;

The image ratio determination module 142, as shown in FIG. 3, is capable of displaying the image object 15 obtained by the first photographic lens 11 and the second photographic lens 12 with respect to the object 2 to be measured on the touch screen. 13 and performing image comparison, and the image comparison can determine the proportion of pixels of the object to be tested on the touch screen 13, for example, the image object 15 occupies 4:7 touch screen (or other size touch) The ratio of the area of the control screen can be obtained by the boundary algorithm (such as business card recognition), and the algorithm can obtain the length/width/high value condition of the captured image object 15 on the touch screen;

The application 14 can first establish a standard data table, as shown in FIG. 4A, capable of setting a standard 3 (known actual object length Lr, actual object width Wr, and actual object height Hr), and the electronic carrier The application 14 of 1 captures the standard 3 at different distances (D _A , D _B , D _C ), as shown in FIG. 4B, the length displayed on the touch screen 13 (Lr _A , Lr _{B )} , Lr _C ), width (Wr _A , Wr _B , Wr _C ) and height (Hr _A , Hr _B , Hr _C ) and the actual object length Lr of the standard 3, the actual object width Wr and the actual object height Hr The relationship establishes a comparison data form, and in addition to establishing three distances, it is possible to establish a plurality of distance lengths Lr, width Wr and height Hr data, and the touch screen width Wm of the touch screen 13 and the length of the touch screen screen Lm can also be recorded as a parameter;

When the object to be tested 4 is as shown in FIG. 5, the object distance calculation module 141 can obtain the actual distance D _{K of} the object 4 to be tested and the electronic vehicle 1 , and then the image ratio determination module 142 can be used to determine The length (Ls _k ), the width (Ws _k ), and the height (Hs _k ) displayed on the touch screen 13 are determined, and then the D _K is determined to be located in the distance range of the data table. If D _K is between D _A and D _B , first calculate the length (Lr _k ), width (Wr _k ) and height (Hr _k ) of the standard 3 in the D _K range. The algorithm is as follows: Length (Lr _k ) = Lr _A -{(D _K -D _A ) / (D _B -D _A )}*(L _A -L _B ) Width (Wr _k )= Wr _A -{(D _K -D _A ) / (D _B -D _A )}*(L _A -L _B ) Height (Hr _k )= Hr _A -{(D _K -D _A )/ (D _B -D _A )}*( L _A -L _B )

Then, the item size calculation module 143 can perform an algorithm by the actual distance D between the electronic vehicle 1 and the object 2 to be tested and the pixel ratio of the image object 15 on the touch screen 13 The actual size of the object to be tested 4 is calculated, and the condition after the calculation is completed can be compared with a pre-stored comparison data form to accurately know the actual size of the object, so when calculating the length of the standard 3 in the D _K range ( After Lr _k ), width (Wr _k ) and height (Hr _k ), the actual object length Ls of the object to be tested 4, the actual object width Ws and the actual object height Hs can be further calculated, and the algorithm is as follows: Length (Ls) = (Ls _k / Lr _k ) * Lr Actual object width (Ws) = (Ws _k / Wr _k ) * Wr Actual object height (Hs) = (Hs _k / Hr _k ) * Hr
