Description
Technical field
The utility model relates to object volume field of measuring technique, specifically, relates to a kind of image collecting device for complex surface and irregularly shaped object cubing.
Background technology
Along with society and industrial fast development, cubing has become a part indispensable in a lot of commercial production, only has the volume measurement device of high precision, high speed, applied range could meet the demand of modern industry production.
At present, domestic research method on this problem mainly adopts drainage, ultrasound volume, CT tomography 3-D view to recover and laser scanning survey volume.The object that drainage can not soak for medicine, chemical industry etc. just cannot detect, and measuring process is inconvenient; Although ultrasound volume, CT tomography 3-D view recover and laser scanning surveys volume measurements accurately, because its instrument price is expensive, complicated operation, is therefore not suitable for promoting.
And existing image collecting device can not be used for the measurement of complex surface and irregularly shaped object volume, its image acquisition is inaccurate, cannot reach the requirements of complex surface and irregularly shaped object cubing.
Utility model content
The utility model overcomes shortcoming of the prior art, provide a kind of image collecting device for complex surface and irregularly shaped object cubing, can dynamic image be clapped, for object volume measurement provides raw data, measuring speed is fast, precision is high, easy to operate.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of image collecting device for complex surface and irregularly shaped object cubing, comprise and measure carrying platform and rotation platform, described rotation platform is driven by motor and rotates, three cameras are set around described measurement carrying platform, corresponding described camera arranges backcloth at the opposite side of described carrying platform, and described camera is arranged on robotic arm, described three camera circular array arrangement, apart from one another by 120 degree, corresponding described camera is also provided with secondary light source.
Further, described measurement carrying platform is that triangle is arranged.
Further, described motor is stepper motor.
Further, described camera is SunTime FX30 camera.
Further, described secondary light source comprises incandescent lamp and light diffusion eyeglass.
Compared with prior art, the beneficial effects of the utility model are:
A kind of image collecting device for complex surface and irregularly shaped object cubing described in the utility model, can clap dynamic image, for object volume measurement provides raw data, robotic arm can finely tune the angle of camera, easy to operate, and capture is accurate.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, is used from explanation the utility model with embodiment one of the present utility model, does not form restriction of the present utility model, in the accompanying drawings:
The vertical view of Fig. 1 a kind of image collecting device for complex surface and irregularly shaped object cubing described in the utility model.
In figure, 1---measure carrying platform; 2---rotation platform;
3---camera; 4---backcloth;
5---mechanical arm; 6---secondary light source.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of image collecting device for complex surface and irregularly shaped object cubing described in the utility model, comprise and measure carrying platform 1 and rotation platform 2, measuring carrying platform 1 is triangle, the leg-of-mutton arrangement that adaptation three cameras 3 are set, rotation platform 2 is rotated by driving stepper motor, measure carrying platform 1 surrounding and three cameras 3 are set, corresponding camera 3 arranges backcloth 4 at the opposite side of carrying platform, camera 3 is arranged on the robotic arm 5 and vertical center shone to rotation platform 2, three camera 3 circular array arrangements, apart from one another by 120 degree, corresponding camera 3 is also provided with secondary light source 6.
Camera 3 is SunTime FX30 colour 1/4, and " CCD camera 3; its operating voltage is 5V, working current 400mA, valid pixel is 680H*480V; scan mode is for lining by line scan; be that Taiwan shows safe industry USB2.0 CMOS/CCD high speed series of products, and adopt the high-end CCD sensitive chip of SONY, have color reducibility good; picture quality is high; sensitivity high, this product is overall Exposure mode output image, is applicable to clap dynamic image.This camera 3 meets our photographing request, for object volume measurement provides high-precision raw data.
Stepper motor often rotates 0.9 degree, camera 3 is clapped and is got an image, because 120 degree is not the integer multiple of 0.9 degree, so the angle intervals of three cameras 3 is set to 120 degree, thus ensure 3 groups captured by three video cameras shooting testees one week, often organizing 400 images is diverse three groups of images, such angle setting is equivalent to us and the anglec of rotation of stepper motor is reduced to 0.3 degree, such setting make Measuring Time become original three points this, measuring accuracy brings up to original three times.
Because the SunTime FX30 camera 3 used takes at most 30 pictures p.s., so control step motor with 0.9 degree for rotation steps, one second rotated 30 times, thus mate with the shooting of camera 3, rotate a circle common needs 40/3 second, then the shooting that each camera 3 completes 400 pictures also needs 40/3 second.
Secondary light source 6 design adopts the incandescent lamp outfit light diffusion eyeglass by colour rendering is good to form, and regulate the angle of secondary light source 6, be irradiated on testee with making the uniform light of secondary light source 6, the interfere information in the image making us shoot is less, improves the accuracy of our cubing.
Shooting background curtain 4 adopts the single color background having larger difference with object under test color, convenience can be provided like this for ensuing image procossing, our measuring accuracy is made to be improved further, backcloth 4 is perpendicular with rotation platform 2, when making camera 3 take testee, in the picture photographed, be full of background image.
The course of work of the present utility model is:
Before measurement, regulate measurement mechanism, regulate three mechanical arms 5, make the angle between three mechanical arms 5 be 120 degree and make each camera 3 aim at the center of rotation platform 2, regulate rotation platform 2 level and make camera 3 be parallel to rotation platform 2, open secondary light source 6, shine to testee with making the uniform light of secondary light source 6, and complex surface object is placed on the centre of rotation platform 2, conveniently carry out cubing.
Stepper motor driven rotary platform 2 rotates, control three cameras 3 simultaneously and take testee simultaneously, when rotation platform 2 rotates 0.9 degree, each camera takes 1 pictures, and the picture of shooting is saved in the file that we specify, for volume computing provides raw data.After rotation platform 2 rotates a circle, each camera 3 have taken 400 pictures altogether, and three cameras 3 photograph 1200 pictures of different camera site altogether.
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
