DETAILED DESCRIPTION OF THE INVENTION

[0015] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0016] 1 to 3, an object dimension measurement system 100 according to a first embodiment of the present invention is used to measure the dimensions of an object 2. The object dimension measurement system 100 includes a measurement module 101 and a calculation module 102. The measurement module 101 includes a depth camera 103. The depth camera 103 is used to measure the object 2 and obtain at least one depth image 3 of the object 2. The calculation module 102 is electrically connected to the measurement module 101 and receives the at least one depth image 3 and calculates dimension data of the object 2.

[0017] As shown in Figures 1 and 2, an object size measuring system 100 according to a second embodiment of the present invention is used to measure the size of an object 2. The object size measuring system 100 comprises a handheld scanning device 104 and electronic equipment 105. The handheld scanning device 104 includes the measurement module 101 described above. The electronic equipment 105 includes the calculation module 102 described above. The object 2 may be an entity such as a parcel or box with a volume greater than 125 cm3. The object size measuring system 100 according to the present invention may be used to measure an object 2 of any shape.

[0018] As shown in FIGS. 1 and 2 , in an embodiment, the object dimension measurement system 100 further includes a display module 108 electrically connected to the computing module 102. The display module 108 is used to display dimensional data of the object 2. Specifically, the computing module 102 and the display module 108 are the host and monitor of the electronic device 105, respectively. The measurement module 101 is installed in the handheld scanning device 104, which may be a gun-type scanner, for example. The display module 108 displays dimensional data of the object 2, including the length, width, and height. While the electronic device 105 shown in FIG. 2 is a laptop, the electronic device 105 may also be a desktop computer, a tablet computer, an all-in-one computer, or the like. Software or an application program for reading the depth image 3 and calculating and displaying the dimensions is installed in the computing module 102 of the electronic device 105. The electronic device 105 and the handheld scanning device 104 are connected via a transmission line (not shown) or via Bluetooth protocol.

[0019] As shown in FIGS. 1 and 2 , in an embodiment, the measurement module 101 further includes a laser projection module 109 electrically connected to the depth camera 103. The laser projection module 109 projects a plurality of laser marks P to indicate the imaging range of the depth camera 103 of the measurement module 101, thereby enabling the measurement position of the object 2 to be identified. In FIG. 2 , the plurality of laser marks P projected by the laser projection module 109 form a rectangular frame pattern, but the present invention is not limited thereto. In other embodiments (not shown), the plurality of laser marks P may form a circle, a cross, or other patterns with an identification function. In addition, the calculation module 102 searches and selects features from the laser marks P in the acquired depth image 3 to form base plane information of the object 2, measure and calculate the outline of the object 2, and calculate dimensional data of the object 2.

[0020] As shown in FIGS. 1 and 3 , a handheld object size measuring device 106 according to a third embodiment of the present invention is used to measure the dimensions of the object 2. The handheld object size measuring device 106 includes a housing 107, the measurement module 101 described above, the computing module 102 described above, and the display module 108 described above. The measurement module 101 and the display module 108 are exposed from the housing 107. The computing module 102 is installed within the housing 107 and may include components such as a circuit motherboard (not shown), a central processing unit (not shown), and a daughterboard (not shown). This embodiment differs from the first and second embodiments in that the measurement module 101, the computing module 102, and the display module 108 are integrated into the handheld object size measuring device 106. The handheld object size measuring device 106 may be, but is not limited to, a tablet device. The necessary components of the depth camera 103, such as a lens (not shown) and a circuit board (not shown), are installed in the handheld object size measuring device 106, and corresponding software or application programs are installed in the handheld object size measuring device 106.

[0021] As described above, the object dimension measurement system 100 and handheld object dimension measurement device 106 of the present invention can quickly obtain the dimension data of the object 2 by capturing a depth image 3 of the object 2 using the depth camera 103 of the measurement module 101, and then the calculation module 102 calculates the dimension data of the object 2 based on the depth image 3.

[0022] The present invention can be embodied in various other forms without departing from its spirit or main characteristics. Therefore, the above-described embodiments are merely illustrative in all respects and should not be interpreted as limiting. The scope of the present invention is defined by the claims and is not limited to the description in the specification. Furthermore, all modifications and variations within the equivalent range of the claims are within the scope of the present invention. [Explanation of symbols]
