Description

Technical Field

[0001] This utility model relates to the field of logistics technology, and in particular to a cargo volume measuring device with supplementary lighting function. Background Technology

[0002] Cargo volume measurement equipment is a key intelligent device in modern logistics, warehousing, and e-commerce. It is mainly used to automatically and efficiently acquire information such as the size, volume, weight, and barcode of goods. Cargo volume measurement is a crucial link in logistics, warehousing, transportation, and trade, directly affecting freight calculation, loading scheme optimization, and warehousing costs. Since cargo volume measurement equipment is generally installed in indoor environments, the light conditions of its working environment are often unstable. These unstable lighting conditions can adversely affect the image acquisition of the equipment, leading to problems such as blurry images and loss of details in the acquired cargo images. This, in turn, affects the accuracy of subsequent image recognition and size calculation, reducing the measurement accuracy and reliability of the equipment. In addition, the color and material of the goods have different effects on the reflection and absorption of light, further exacerbating the interference with the measurement results. Utility Model Content

[0003] This invention provides a cargo volume measuring device with supplementary lighting function, which can effectively solve the above problems.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a cargo volume measuring device with supplementary lighting function, comprising:

[0006] The platform has a lifting mechanism on one edge, slide rails on both sides, and a lead screw in the middle. A light shield slides on the lifting mechanism, and a camera and a distance sensor are installed in the center inside the light shield. Several supplementary lights surround the camera. A computer display and an electronic scale display are installed on the side of the lifting mechanism closest to the platform. A scale platform is located above the platform, and a positioning mechanism is embedded in the scale platform. A cavity is provided inside the platform for placing a computer.

[0007] As a further improvement, the weighing platform is provided with a first slide groove and a second slide groove arranged perpendicularly to each other, and the second slide groove is located below the first slide groove and passes through the first slide groove.

[0008] As a further improvement, the light shield is also evenly provided with several auxiliary cameras.

[0009] As a further improvement, the positioning mechanism includes a first positioning component and a second positioning component, wherein the first positioning component is disposed in the first slide groove and the second positioning component is disposed in the second slide groove.

[0010] As a further improvement, the first positioning component is provided with a first left-hand and right-hand lead screw, and a first slider is provided at both ends of the first left-hand and right-hand lead screw. A first baffle is provided on each of the first sliders. One end of the first left-hand and right-hand lead screw is connected to a first coupling, and the other end of the first coupling is connected to a first motor.

[0011] As a further improvement, the second positioning component is provided with a second left-hand and right-hand screw, and a second slider is provided at both ends of the second left-hand and right-hand screw. A second baffle is provided on each of the second sliders. One end of the second left-hand and right-hand screw is connected to a second coupling, and the other end of the second coupling is connected to a second motor.

[0012] As a further improvement, the lifting mechanism is provided with auxiliary rods on both sides of the lead screw.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes several supplementary lights arranged around a camera, equipped with a light sensor, to automatically adjust the brightness of the lights according to the ambient light. This effectively improves problems such as blurred images and loss of detail caused by unstable lighting, reduces interference from differences in light reflection and absorption due to the color and material of the goods, and ensures clear and accurate images captured by the camera, providing a reliable basis for subsequent size calculations.

[0022] Reference Figure 1-2 As shown, a cargo volume measuring device with supplemental lighting function includes:

[0023] A storage platform 1 has a lifting mechanism 2 on one edge. Both sides of the lifting mechanism 2 have slide rails, and a lead screw is located in the middle. A light shield 3 is slidably mounted on the lifting mechanism 2. A camera 6 and a distance sensor are installed in the center of the light shield 3. Several supplementary lights 9 are arranged around the camera 6. A computer display screen 7 and an electronic scale display 8 are installed on the side of the lifting mechanism 2 closest to the storage platform 1. A weighing platform 4 is located above the storage platform 1, and a positioning mechanism 5 is embedded in the weighing platform 4. A cavity is provided inside the storage platform 1 to house the computer. The supplementary lights 9 arranged around the camera 6, equipped with a light sensor, can automatically adjust the brightness of the lights according to the ambient light, effectively improving problems such as blurred images and loss of details caused by unstable lighting. This reduces interference from differences in light reflection and absorption caused by the color and material of the goods, ensuring that the images captured by the camera 6 are clear and accurate, providing a reliable basis for subsequent size calculations.

[0024] Furthermore, in order to adjust the distance between the camera and the goods and improve the accuracy of image acquisition and measurement data, a lifting mechanism 2 is provided. Slide rails are provided on both sides of the lifting mechanism 2. A light shield 3 has side sliders on both sides near the lifting mechanism 2. These side sliders are adapted to the slide rails, facilitating the movement of the light shield 3 on the lifting mechanism 2. A lead screw is provided in the middle of the lifting mechanism 2, and auxiliary rods are provided on both sides of the lead screw. The light shield 3 is connected to the lead screw and auxiliary rods on the side near the lifting mechanism 2. One end of the lead screw is connected to a drive motor via a coupling. The drive motor is connected to a computer via a conversion circuit to drive the lead screw of the lifting mechanism 2, thereby driving the lifting and lowering of the light shield 3. By adjusting the distance between the light shield 3 and the weighing platform 4, the light intensity of external light entering the shooting area of ​​the camera 6 is adjusted. A computer display screen 7 and an electronic scale display 8 are installed on the side of the lifting mechanism 2 near the platform 1.

[0025] Inside the light shield 3, a camera 6 and a distance sensor are installed in the center. Several supplementary lights 9 are arranged around the camera 6, with the angle between adjacent supplementary lights 9 ranging from 30° to 45°. Each supplementary light 9 is equipped with a light sensor, which is electrically connected to both the supplementary light 9 and a computer. These sensors are used to collect the ambient light intensity around the device. Based on the number and position of the supplementary lights 9, the computer divides the camera 6's shooting area into several illumination zones, each corresponding to one supplementary light 9. The supplementary lights 9 have preset values, which can be set according to common goods materials. Several auxiliary cameras 10 are also evenly arranged on the light shield 3. The camera 6 is electrically connected to the computer and is used to collect images of the goods to be measured and feed them back to the computer. The distance sensor is electrically connected to the computer and is used to measure the height of the camera 6 and the range of the shooting area. The camera 6 measures the height of the goods to be measured and sends the data back to the computer. The computer is connected to the camera 6, the distance sensor, the display, and the conversion circuit. It is used to analyze and calculate the collected images of the goods to be measured and output the length, width, and height of the goods, as well as control the lifting mechanism 2 to lift. The computer display screen 7 is connected to the computer and is used to display the length, width, and height of the goods to be measured. The electronic scale display 8 is connected to the scale platform 4 and is used to display the weight of the goods to be measured. The auxiliary camera 10 is electrically connected to the computer and is used to collect images of the goods to be measured from other angles and send them back to the computer. In this embodiment, two auxiliary cameras 10 are set up, which are respectively set at two opposite corners of the light shield 3 to collect oblique views of the side and top of the goods to capture the height contour of the goods. All images collected by the cameras are transmitted to the computer in real time. The computer automatically stitches the images to generate the original data of the three-dimensional contour model of the goods, thereby improving the accuracy of the measurement data.

[0026] The light sensor collects the brightness of each illuminated area in real time. The computer compares the brightness of the illuminated area with the preset value. If the brightness of a certain area is lower than the benchmark value, the computer controls the corresponding fill light 9 to increase the brightness. If the brightness of a certain area is higher than the benchmark value, the computer controls the corresponding fill light 9 to decrease the brightness. If the fill light 9 in a certain illuminated area malfunctions, the computer automatically adjusts the adjacent fill lights 9 to compensate, ensuring uniform lighting in the shooting area.

[0027] In this embodiment, the camera 6 is mounted on the light shield 3, which allows the camera 6 to be moved up and down, expanding and narrowing the shooting range of a single camera 6, thereby accurately capturing images of goods of different sizes for image processing; at the same time, by setting the light shield 3 and the supplementary light 9, it is ensured that the image acquisition process is not easily affected by light factors, resulting in unclear edge contours of the acquired image; the lifting mechanism 2 can automatically lift up and down, which can be specifically controlled by a computer to drive the motor to move up and down.

[0028] As a preferred implementation, a barcode reader for the goods to be tested can also be set up next to camera 6. This camera can collect the barcode of the goods to be tested while capturing the image and weighing them, and send the data back to the computer. The computer can then identify the goods to be tested based on the barcode and display their weight, volume, freight, and serial number on the computer screen, making it convenient for operators to confirm the status of the goods to be tested.

[0029] Furthermore, to ensure the goods are centered within the camera area of ​​camera 6, a positioning mechanism 5 is embedded in the weighing platform 4. The weighing platform 4 has a first and a second sliding groove arranged perpendicularly to each other, with the second sliding groove located below and penetrating the first sliding groove. The positioning mechanism 5 includes a first positioning component 51 and a second positioning component 52. The first positioning component 51 is located in the first sliding groove, and the second positioning component 52 is located in the second sliding groove. The first positioning component 51 is equipped with a first left-right rotating lead screw, with first sliders at both ends of the first left-right rotating lead screw. Each first slider is equipped with a first baffle. One end of the first left-right rotating lead screw is connected to a first... A coupling is provided, with the other end of the first coupling connected to a first motor; a second positioning assembly 52 is provided with a second left-hand and right-hand lead screw, with a second slider at both ends of the second left-hand and right-hand lead screw, and a second baffle on each second slider; one end of the second left-hand and right-hand lead screw is connected to a second coupling, and the other end of the second coupling is connected to a second motor; the first motor and the second motor are electrically connected to a computer and are used to control the rotation of the first left-hand and right-hand lead screws and the second left-hand and right-hand lead screws, so that the first slider and the second slider move closer to the middle position of the weighing platform 4; a weighing sensor is provided on the weighing platform 4, and the weighing sensor is electrically connected to the computer and is used to measure the weight of the goods.

[0030] In this embodiment, the goods to be weighed can be placed on the weighing platform 4 to achieve simultaneous weighing. The weight of the goods is displayed on the electronic scale display 8, which can also feed back the specific weight value to the computer. The computer can display the weight and volume of the goods on the computer display screen 7. At the same time, the pre-set freight calculation system can read the weight and volume of the goods and output the actual freight cost. When the goods are placed on the weighing platform 4, the weighing sensor detects the weight signal and transmits the signal to the computer. After receiving the signal, the computer drives the first motor and the second motor. The first motor drives the first left-hand and right-hand lead screw to rotate through the first coupling, and the second motor drives the second left-hand and right-hand lead screw to rotate through the second linkage. Since the threads at both ends of the first left-hand and right-hand lead screws are in opposite directions... Its rotation causes the first sliders at both ends to move relative to each other along the first slide groove. The first baffles on the first sliders move with the sliders, pushing the goods from both sides until the goods are aligned to the preset center position in the direction of the first slide groove. Similarly, the rotation of the second left and right screws causes the second sliders at both ends to move relative to each other along the second slide groove. The second baffles on the second sliders push the goods from the other sides, aligning the goods to the preset center position in the direction of the second slide groove. When the baffles in both directions have pushed the goods to the center position, the computer receives the relevant positioning signal, which can be achieved, for example, by setting a position sensor on the slider or baffle. The computer then controls the first and second motors to stop working or controls the first and second sliders to return to their original positions. The positioning mechanism completes the positioning and calibration of the goods. At this time, the goods are in the optimal shooting area of ​​the camera.

[0031] Further, the specific embodiments of this utility model are as follows:

[0032] First, adjust the position of camera 6 so that its shooting angle is parallel to the weighing platform 4 to ensure that a top-view image of the goods to be measured can be captured. After the goods to be measured are placed on the weighing platform 4, the computer receives a signal from the weighing sensor and drives the first motor and the second motor to center the goods on the weighing platform 4. The computer adjusts the illumination intensity of the supplementary light 9 through the light sensor to keep the illumination intensity of the shooting area of ​​camera 6 consistent. The computer determines whether the edges of the goods to be measured are all in the image through camera 6 and sends a raising or lowering command to the lifting mechanism 2. The drive motor rotates to raise or lower the light shield 3. The height is transmitted back to the computer through the distance sensor until the edges of the goods to be measured are all in the image. The computer sends a stop command to the drive motor. The computer adjusts the illumination intensity of the supplementary light 9 again through the light sensor. The computer analyzes the image captured by camera 3 to obtain information such as the length, width, height and weight of the goods and displays this information on the computer display screen 7.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
