Abstract
The invention discloses a method for measuring volume of a bomb chamber. The method comprises the following steps: (1) acquiring an image of a bomb to be measured through a video camera, inputting the acquired image into a computer, and calculating the overall volume V1 of the bomb through the computer; (2) weighing the net weight of the bomb to be measured through an electric scale, and converting the net weight of the bomb into an entity volume V2 through the computer; and (3) calculating the volume V of the bomb to be measured through the computer, wherein V equals to V1 minus V2. Meanwhile, the invention also discloses a device for measuring the volume of the bomb chamber. By utilizing the method and the device, the volume of the bomb chamber can be simply, quickly and accurately detected, non-contact detection is performed so as to completely overcome the defects that in the prior art, large error is large and the inner cavity of the bomb is wetted because a 'water weighing method' is adopted, and the drying process is reduced; and by utilizing the method and device for measuring the volume of the bomb chamber, online automatic detection can be realized easily.
Description
Technical field
The present invention relates to a kind of method and device thereof of measuring the body chambervolume.
Background technology
For a long time, military enterprise is in the shell production run, " title water law " mainly adopted in measurement to the body chambervolume, promptly utilizes the body coyote hole to inject that the front and back of water are of poor quality to record the volume of body coyote hole indirectly divided by the density of water, and then estimates its explosive load and charge density.Yet this method is not only time-consuming, take a lot of work, and the error of testing result is also bigger, does not adapt to the requirement of modern war production.This method is owing to need to inject liquid, also needs after the measurement shell body such as is dried at processing, and complex operation and measuring accuracy are not accurate enough.This method can only be surveyed sample the body of producing in batches, also will table look-up multiple working procedures such as evaluation through adjusting; Sense cycle is long, and efficient is low, and means fall behind, and can not realize the automatic detection on the production line.
Summary of the invention
At weak point of the prior art, the invention provides a kind of volume to the body coyote hole carry out simply, fast, non-contact detecting, and the method and the device thereof of the high measurement body chambervolume of accuracy.It is big that the method for this measurement body chambervolume and device thereof have overcome available technology adopting " title water law " error fully, and the shortcoming of drenching the body inner chamber has reduced the oven dry flow process; Easily on production line, realize simultaneously detecting automatically.
A kind of method of measuring the body chambervolume provided by the invention comprises the steps:
(1), body to be measured is placed on the place ahead of camera lens, by video camera body is carried out image acquisition, and, go out the overall volume V1 of body by COMPUTER CALCULATION the image input computing machine of gathering;
(2), body to be measured is placed on the electronic scale, take by weighing the nt wt net weight of body, and with the nt wt net weight input computing machine of the body that takes by weighing, the nt wt net weight of body is converted to entity volume V2 by computing machine by electronic scale;
(3) volume V by COMPUTER CALCULATION body coyote hole to be measured, V=V1-V2.
Further, in step (1), video camera is at body to be measured under the condition of illumination makes a video recording.
The present invention also provides a kind of device of measuring the body chambervolume, comprises electronic scale, video camera and computing machine; Shown in the weight signal input computing machine that takes by weighing of electronic scale, the picture signal input computing machine of described camera acquisition; When body to be measured was placed on the electronic scale, the camera lens of video camera was corresponding with body to be measured.
Further, also comprise lighting device, when body to be measured was placed on the electronic scale, the light that described lighting device sends was corresponding with body to be measured.
A kind of method of measuring the body chambervolume of the present invention and device thereof compared with prior art have following advantage:
1, the present invention adopts the volume of camera acquisition body to be measured, adopt electronic scale to take by weighing the nt wt net weight of body to be measured, and with the volume and weight of body to be measured input computing machine, go out the overall volume of body to be measured by COMPUTER CALCULATION, and the nt wt net weight of body to be measured is converted to the entity volume of body to be measured, both differences are the volume of body coyote hole, and are simple, quick, accurate with the volume that installs detection body coyote hole by the method, and detection is a non-contact detecting.
2, to have overcome available technology adopting " title water law " error fully big for the method for this measurement body chambervolume and device thereof, and the shortcoming of drenching the body inner chamber has reduced the oven dry flow process.
3, this method and device thereof of measuring the body chambervolume is easily realized online automatic detection.
Description of drawings
Fig. 1 is a kind of structural representation of measuring the device of body chambervolume of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
Fig. 1 is a kind of structural representation of measuring the device of body chambervolume of the present invention, as shown in the figure.The device of measuring the body chambervolume comprises electronic scale 1, video camera 2, computing machine 3, lighting device 5 and support 6.Body 4 to be measured is placed on the electronic scale 1, and lighting device 5 is arranged in a side of body 4 to be measured, and the light that lighting device 5 sends is corresponding with body to be measured 4, provides light source to body 4 to be measured, so that video camera 2 can collect distinct image.Video camera 2 is installed on the support 6, the height by adjusting support 6 and the focal length of video camera 2 just can be gathered the image of body 4 to be measured, video camera 2 is connected with computing machine 3 by signal cable, imports in the computing machine 3 by the image that signal cable is gathered video camera 2.The weight signal that electronic scale 1 takes by weighing is equally by signal cable input computing machine 3.
A kind of method of measuring the body chambervolume comprises the steps:
(1), body to be measured is placed on the place ahead of video camera, adjust the height of focus of camera and bracing frame, image by the camera acquisition body, and the image of gathering imported computing machine by signal cable, in computing machine, utilize image processing software that image is carried out analyzing and processing, set up measurement model behind the picture that obtains handling, and calculate the overall volume V1 of body to be measured;
(2), body to be measured is placed on the electronic scale, take by weighing the weight of body by electronic scale, and the weight that takes by weighing imported computing machine by signal cable, according to the weight of airframe material proportion, body and the relation of body entity volume, computing machine is converted to the weight of body the entity volume V2 of body;
