【Specific embodiment】

The utility model mainly discloses a kind of hardware structure of measuring apparatus, with the accompanying drawing for hereinafter being compareed, main table Up to the structural representation relevant with the feature of the utility model one exemplary embodiment, to help it will be appreciated by those skilled in the art that not Also need not completely be drawn according to actual size, first explanation.

See Fig. 1, the utility model proposes a kind of measuring apparatus 10, be used to measure one group of outside of object under test 900 Size, comprising main support 100 and optical sensing instrument 300.Main support 100 includes one group of vertical support frame 110 being set up on ground With a horizontal stand 120 for being set up in the top of vertical support frame 110, object under test 900 is placed in the lower section of horizontal stand 120.

See Fig. 3, optical sensing instrument 300 includes 310, data transmission device 320 of a storage device and double takes the photograph As head device 330.See Fig. 1, Double-camera device 330 is arranged at horizontal stand 120, and Double-camera device 330 capture Mirror is used to absorb multiple images of object under test 900 to set down.It is double in order to provide the dimensional measurement for large cargo Cam device 330 is not less than 2.5 meters with the vertical range on ground, is more preferred with 3 meters.Storage device 310 is used to store double taking the photograph As multiple images of the object under test 900 that head device 330 is absorbed, data transmission device 320 is outside by the multiple images for storing Output.

It is that the utility model is different from one very important technical characteristic of prior art using Double-camera device 330. The China's Mainland patent of invention CN201210052320.2 of prior art is that measurement object is true after using single camera capture Size, but effect and the degree of accuracy be not good.The utility model uses Double-camera device, and two positions of camera are not same Individual place, needs to be separated by a small distance each other；Because the position of two cameras is not in the same localities, for object under test 900 images for being absorbed just have the difference at visual angle；Because image has visual angle difference, object under test can be just drawn by calculation 900 depth and width；Length, width, the height of object under test 900 can be just obtained by translation operation again.Drilled as image Algorithm, the technology emphasis that not the utility model to be emphasized, similar algorithm refers to China's Mainland patent of invention in the prior art CN201210450044.5 and CN200810050630.4.

See Fig. 1, preferably, vertical support frame 110 includes a pair or so the opposite columns 111 set up, the frame of horizontal stand 120 Located at the top of a column 111, main support 100 is set to form a gate framework, to facilitate object under test 900 to be moved to gate Measured below framework.

See Fig. 1, column 111 includes two the first truss 112 and at least one second truss 113, two the first truss 112 inclined upward settings, and top is combined with each other, the second truss 113 is horizontally placed on two lower half of the first truss 112 Between portion, the first truss 112 and the second truss 113 is set to form up-narrow and down-wide triangular arrangement.This triangular arrangement it is vertical The stability of post 111 is higher, if the second truss 113 is more, stability is more preferable.

See Fig. 2, the another embodiment of column 111, column 111 includes the 3rd truss 114 and a underframe 115, the vertical upward setting of the 3rd truss 114, the bottom for being arranged at the 3rd truss 114 of the level of underframe 115.

See Fig. 1 and Fig. 2, in order to extend the use occasion of measuring apparatus 10, can be provided with the bottom of column 111 many Individual movable pulley 116, enables main support 100 to move horizontally.For the constant superduty goods of movement, can by movable pulley 116, Measuring apparatus 10 are moved to superduty goods top, to measure.

See Fig. 3, data transmission device of the present utility model 320 can further include a radio transmitting device 321, will store up The multiple images deposited wirelessly outwards are transmitted.If it is considered that distance long-distance transmission more long, can use 802.11b/ The wireless communication protocols such as g/n；If it is considered that confidentiality is transmitted, NFC near field communication protocols can be used；Using Bluetooth transmission also Can, but because the data volume of image is larger, the communication protocol using bluetooth more than 4.0 is preferable.

The utility model can not also use wireless way for transmitting data, and now data transmission device 320 includes at least one USB connector, can easily in image copies to other external data devices by USB connector.

Substantially, the only pick-up image of measuring apparatus of the present utility model 10, the size without carrying out object under test 900 is instant Computing.The size of object under test 900 is by data transmission device 320 to outside arithmetic facility, such as the center prison in warehouse Control computer, and carry out size computing.But it is lifting calculation efficiency, preferably, see Fig. 2, the utility model also can again include one Individual real-time operation device 400, based on multiple images that Double-camera device 330 is absorbed, calculation immediately draws object under test 900 External dimensions.

Preferably, please continue that Fig. 2 is seen, measuring apparatus of the present utility model are additionally provided with a display device 500, Neng Goucheng The image of existing object under test 900, including history image and instant video.Real-time operation device is provided with measuring apparatus 10 simultaneously In the case of 400, display device 500 can also simultaneously show the external dimensions of object under test 900.

See Fig. 4, it is considered to which the size of object under test 900 is different, especially highly different situations, the utility model Measuring apparatus 10 horizontal stand 120 further include a Z axis mobile station 121, be used to carry Double-camera device 330 Move in the vertical direction, thereby with the degree of accuracy of enhancement measurement.We it must be understood that one apart near wisp and one away from Big object away from, may be presented identical size in an image.In order to promote the degree of accuracy of measurement and calculation, adjustment is double The position of cam device 330, make its maintain that one section specific with the top of object under test 900 or default distance in, energy The degree of accuracy of measurement is significantly improved, lowers calculation error.Mode of operation is to take two-phase measuring method in practice, the first stage elder generation The height and position at the top of object under test 900 is measured, i.e., by Double-camera device 330 in peak position measuring targets The multiple images of 900 intakes, calculate the height and position at the top of object under test 900, and then Z axis mobile station 121 carries double shootings Head device 330 is moved in the vertical direction to default distance；Now carry out second stage measurement, i.e. Double-camera device 330 Measuring targets 900 absorb multiple images to calculate its accurate external dimensions again again.

The measuring apparatus 10 that the utility model is proposed, using overhead door frame shaped framework, can measure large-scale object under test 900 external dimensions；Drilled after multiple images that different visual angles are shot with 330 measuring targets of Double-camera device 900 Calculate, can fast and accurately estimate length, width, height of object under test 900 etc., further more can automatically calculate its volume. This framework carries out manual measurement without personnel, and efficiency greatly improved.

The utility model preferably implementation method is the foregoing is only, right model of the present utility model is not limited to Enclose；Description more than simultaneously, should be appreciated that and implement for the special personage of correlative technology field, therefore other are without departing from this practicality The equivalent change or modification completed under new disclosed spirit, in should be included in claim.
