The present invention relates to a box structure recognition and measurement system, particularly to one that has a mobile device installed with a laser module and a measurement application program to instantly recognize a box structure in an image and further measure the length, width and height of the box structure.
Online shopping has been one of the favorite choices for shoppers. When a product is ordered online, the merchandizer would put the ordered product into a box for shipment to the shoppers' house after the payment is made, and it has been a crucial issue of the length, width, height and volume of the boxes, in view of shipping costs and spaces for one shipment. However, even though online shopping has become such a common daily activity, there is still no such measurement system for quick and precise recognition and measurement of the box structures for the purpose of shipping costs calculation and for making use of the space for one shipment as much as possible.
A primary objective of the present invention is to provide a box structure recognition and measurement system that is operated by a mobile device installed with a laser module and a measurement application program, in order to instantly recognize a box structure and learn the specific measurement data of the box.
To achieve the objects mentioned above, the present invention comprises a mobile device including a first microprocessor, a first screen electrically connected to said first microprocessor, a memory unit electrically connected to said first microprocessor, a camera electrically connected to said first microprocessor and a gyroscope electrically connected to said first microprocessor; a laser module coupled to said mobile device to be operated by said first microprocessor; and a measurement application program installed on said memory unit of the mobile device to be operated by said first microprocessor, upon being activated by said first microprocessor, said measurement application program having the laser module projecting a laser point, the gyroscope detecting a projection angle of said laser point, the camera of the mobile device being turned on and then the first screen displaying a window with a baseline for recognition and measurement, whereby a box with a datum surface is targeted in the window on the first screen of the mobile device and the camera of the mobile device is adjusted to focus on the box for the laser module to project a laser point onto the box; then the mobile device is manually moved to have the baseline in the window to be aligned with a horizontal position displayed in the window for retrieving an image with the box, said image being stored in the memory unit of the mobile device and then processed by the first microprocessor for calculation and measurement operation, a first edge line, a second edge line, a third edge line, a fourth edge line, a fifth edge line, a sixth edge line and a seventh edge line being recognized, then a first measurement point formed at an intersection point of said first and second edge lines, a second measurement point formed at an intersection point of said first and third edge lines, a third measurement point formed at an intersection point of said second, fourth and fifth edge lines, a fourth measurement point formed at an intersection point of said third, fourth and sixth edge lines, a fifth measurement point formed at an intersection point of said fifth and seventh edge lines and a sixth measurement point formed at an intersection point of said sixth and seventh edge lines being recognized as well, thereby completing the recognition and measurement process of the box.

The first screen further includes a volume data displayed thereon; the volume data is a result calculated by the first, second and third measurement data.
The first screen further displays a measurement unit button, a file opening button, a box structure recognition button, a measurement operation button, a flashlight button and a laser display button in the window.
Furthermore, the mobile device is a smartphone, a tablet or a rangefinder, and the laser module is coupled to and disposed either inside or outside the mobile device.
A metallic piece is further attached on a back surface of a housing of the mobile device, and the laser module further has a magnet to be attached to the metallic piece for disposing the laser module onto the housing of the mobile device.

The second wireless transmitter 23 is electrically connected to the second microprocessor 22 and coupled to the first wireless processor 16 of the mobile device 10. The driving circuit 24 is electrically connected to the second microprocessor 22. The light-emitting module 25 is electrically connected to the driving circuit 24. The light-receiving module 26 is adjacent to the light-emitting module 25 and is electrically connected to the driving circuit 24. A case housing 27 is further arranged to have the carrier board 21, the second microprocessor 22, the second wireless transmitter 23, the driving circuit 24, the light-emitting module 25 and the light-receiving module 26 disposed therein, and the case housing 27 further includes an opening 271 arranged at a side thereof.

Thereby when the light-emitting module 25 emits a laser beam L, the laser beam L is reflected by the reflector unit 28 to be emitted out from the opening 271 of the case housing 27 to the box 40; then the box 40 further reflects the laser beam L back to the light-receiving module 26 so that the second microprocessor 22 is able to perform calculation of a distance D between the laser module 20 and the box 40. The case housing 27 further has a second screen 29 thereon, electrically connected to the second microprocessor 22 for displaying the result of the distance D calculated thereon. But the present invention is not limited to such application.
With the structures disclosed above, the present invention has the mobile device 10, the laser module 20 and the measurement application program 30 to form the box structure recognition and measurement system 50. The system can instantly recognize a box structure in an image and further obtain the measurement results of the length, width and height of the box structure; even further calculation results of the measured numbers are accessible simply by operation of the system. Such function is exactly the solution for the merchandizers to the problem of imprecise and improper estimation of the volume of the boxes and the spaces for stacking the boxes for shipment without spending too much time in the calculation process.
Although particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
