[0081] In some embodiments, obtain continuous monitoring images within a preset time period, analyze the continuous monitoring images, and determine the status change of the weighed item; according to the status change, determine whether there is any moment when the status changes from irregular to uniform; if so, determine the moment when the status changes from irregular to uniform as the accurate moment, and obtain the accurate weighing data at the accurate moment, and determine the accurate weighing data as the weight of the weighed item.

[0082] The preset time period can be a pre-set time range for monitoring and recording activities or events, which is stored in the server in advance and is called when in use.

[0083] The continuous monitoring images can be a continuous sequence of images continuously captured by a camera within the preset time period.

[0084] The status change can be various status changes such as movement, vibration, and stillness experienced by the weighed item within the preset time period.

[0085] Any moment can be any specific time point within the preset time period.

[0086] Irregular change can be that the status change of the weighed item has no obvious regularity and is random or disordered.

[0087] Uniform change can be that the status change of the weighed item presents regular uniform motion or stillness.

[0088] The accurate moment can be the time point when the status of the weighed item changes from irregular to uniform within the preset time period.

[0089] The accurate weighing data can be the electronic scale force data obtained by the weighed item at the accurate moment.

[0090] Specifically, a camera is used to capture continuous monitoring images of the weighed item during a preset time period. Preprocessing operations such as denoising and contrast enhancement are performed on the captured monitoring images to improve the image quality. Image processing techniques are utilized to analyze the monitoring images, track the position and status of the weighed item, and identify changes. Combining with the pressure sensor data of the electronic scale, the dynamic force condition of the weighed item on the scale is monitored. Combining with the pressure sensor data of the electronic scale, the dynamic force condition of the weighed item on the scale is monitored. If it is detected that the state transition changes from irregular change to uniform change, then this moment is determined as the accurate moment with the most accurate weight. The data of the pressure sensor detected at the accurate moment is obtained as the accurate weighing data of the item, thereby determining the weight of the weighed item.

[0091] Through this solution, continuous image data of the weighed item within a preset time period is collected. Through image processing techniques, the position and status of the weighed item in the image are identified and tracked. The status change of the weighed item during the monitoring period is determined, such as whether it changes from irregular change to uniform change. The accurate moment when the status changes from irregular change to uniform change is found, and this moment corresponds to the moment when the force on the item is stable. The force data of the electronic scale is obtained at the accurate moment, and these data reflect the true weight of the item. The weight of the weighed item is calculated based on the force data at the accurate moment, ensuring the accuracy of the weighing result.

[0092] In some embodiments, the status change is analyzed to determine the movement speed and movement direction of the weighed item at the accurate moment; according to the movement speed and movement direction, the impact force of the weighed item on the electronic scale is determined; the basic weighing data at the accurate moment is obtained, and according to the impact force, the basic weighing data is adjusted to obtain the accurate weighing data.

[0093] The movement speed can be the instantaneous speed of the weighed item at the accurate moment.

[0094] The movement direction can be the instantaneous movement direction of the weighed item at the accurate moment.

[0095] The impact force can be an instantaneous additional force generated on the electronic scale due to the rapid placement, throwing, etc. of the weighed item.

[0096] The basic weighing data can be the weight reading displayed by the electronic scale when the weighed item is in a stationary state.

[0097] Specifically, image processing technology is used to analyze continuous monitoring images to detect changes in the position, speed, and acceleration state of the weighed item. A dynamic detection algorithm is used to determine the movement speed and direction of the item. Combining the mass and acceleration of the item, mechanical formulas in physics are used to estimate the impact force of the item on the electronic scale. At the precise moment when the item is in a static state, basic weighing data is obtained from the sensors of the electronic scale, and then, based on the impact force of the item, the basic weighing data is corrected to reflect the true weight of the item under dynamic conditions, and the adjusted precise weighing data is output.

[0098] Through this solution, by continuously analyzing the monitoring images, the movement trajectory of the item can be traced, so as to obtain the speed and direction information of the item at the precise moment, which helps to analyze the dynamic behavior of the item on the scale. After identifying the speed and direction of the item, the magnitude of the impact force of the item on the scale surface is calculated, which helps to correct the weighing error caused by dynamic movement. The weighing data obtained at the precise moment is the weight of the item when it is stationary, which is the basis of weighing, but needs to be adjusted in a dynamic environment. By adjusting the basic weighing data, the weighing error caused by the movement of the item can be eliminated or reduced, so as to obtain data closer to the true weight of the item. The weight corrected after the dynamic behavior of the item obtains the precise weighing data, which helps to improve the weighing accuracy and reliability of the electronic scale in a complex environment.

[0099] In some embodiments, according to the movement direction, it is determined whether the weighed item impacts the electronic scale within the first preset time period at the precise moment; if an impact occurs, then according to the item composition and item type, the theoretical density of the weighed item is determined; according to the movement speed and the state change situation, the impact duration is determined; according to the theoretical density of the item, the item volume, the impact duration, and the movement speed, the impact force of the weighed item on the electronic scale is determined.

[0100] The theoretical density of the item can be a density value obtained by looking up standard data or using a prediction model according to the composition and type of the item.

[0101] The impact duration can be the time length when the weighed item contacts the electronic scale and generates a force.

[0102] The first preset time period can be a time period that may affect data reading when obtaining weight data at the precise moment, which may be one second or 0.1 second. The specific time can be set by the production personnel and is not limited in this embodiment.

[0103] Specifically, through the monitoring image analysis technology, the moving direction of the weighed item at a precise moment is analyzed. Combining the moving direction of the item and the dynamic monitoring data of the electronic scale, it is determined whether the item will impact the electronic scale within the first preset period when the weight data is read at the precise moment. If so, according to the composition and type of the item, the standard substance density table is searched or a machine learning model is used to determine the theoretical density of the item. By analyzing the moving speed and state change of the item, the contact time between the weighed item and the electronic scale is calculated to obtain the impact duration. Furthermore, using the momentum theorem or impact force formula in physics, combined with the theoretical density of the item, the volume of the item, the impact duration, and the moving speed, the magnitude of the impact force is calculated.

[0104] Through this solution, by analyzing the moving direction of the item, it can be determined whether the item impacts the electronic scale during the placement process, thereby deciding whether further dynamic force analysis is required. Determining the composition and type of the item helps to select the correct density data or model, and also helps to accurately calculate the impact force. The theoretical density of the item is the basis for calculating the impact force, which affects the magnitude of the impact force and the force-bearing situation of the electronic scale. The impact duration is an important factor in calculating the impact force, which determines the duration of the impact force of the weighed item on the electronic scale. The volume of the item and the theoretical density of the item determine the mass of the item, which in turn affects the magnitude of the impact force. Through physical formulas and known parameters, the impact force of the weighed item on the electronic scale is calculated.

[0105] In some embodiments, to determine the impact force of the weighed item on the electronic scale according to the theoretical density of the item, the volume of the item, the impact duration, and the moving speed, the following formula is used: Where, represents the impact force; represents the volume of the item; represents the theoretical density of the item; represents the moving speed; represents the impact duration; represents the moving direction correction factor.

[0106] The moving direction correction factor can be a coefficient used to adjust the impact force deviation caused by the non-perpendicularity between the moving direction of the item and the surface of the electronic scale.

[0107] Specifically, the volume of an object determines the size it occupies in space and affects the kinetic energy that may be generated during a collision. The speed of an object's movement is an important factor affecting the impact force. The higher the speed of the object during impact, the greater the kinetic energy generated, and thus the stronger the impact force. The impact duration determines the time of force application. The shorter the impact duration, the stronger the instantaneous effect of the impact force may be. Density is the ratio of an object's mass to its volume, and the theoretical density reflects the texture and inherent mass characteristics of the object. The greater the theoretical density, the greater the mass of the object, and thus the greater the impact force on the scale may be. The motion direction correction factor is a coefficient used to adjust the direction of the impact force, taking into account the relative angle between the object's motion direction and the surface of the electronic scale. Substitute all the calculated parameters into the formula to calculate the impact force of the object on the electronic scale.

[0108] Through this solution, by combining multiple factors such as the volume, density, speed, and impact duration of the object, the magnitude of the impact force can be accurately described. The introduction of the motion direction correction factor can adjust the component in the direction of the impact force, taking into account real-world factors such as the inclination and collision angle of the object. Compared with simple mechanical formulas, the calculation formula takes into account the speed and duration factors during impact, can provide more accurate mechanical analysis, helps to evaluate the impact resistance of the electronic scale, and avoids errors or damage. It is not only applicable to different types of objects but also can adjust parameters to adapt to different application scenarios, with strong flexibility.

[0109] In some embodiments, according to the light refraction and / or light reflection conditions, determine the light image area; adjust the image contrast of the light image area to determine the object edge and object details in the light image area; adjust the object monitoring image according to the object edge and object details to obtain an accurate image.

[0110] The light image area can be the area in the image affected by light refraction and / or light reflection.

[0111] The image contrast can be the degree of difference between the bright and dark areas in the image.

[0112] The object edge can be the contour line or boundary line of the object in the image.

[0113] The object details can be the tiny features such as the texture and color change on the object surface.

[0114] Specifically, through image processing technology, regions affected by light refraction and / or light reflection are identified. Image segmentation techniques such as threshold segmentation and edge detection are used to isolate these regions. The contrast of the regions affected by light is enhanced to improve the contrast between the object and the background, making the object edges clearer. Edge detection algorithms are used to determine the edges of the object. The detailed features of the object are enhanced through image sharpening techniques or deep learning models. Based on the determined object edges and details, corrections such as noise removal, filling of edge holes, and smoothing of edges are performed on the surveillance image. After adjustment, an accurate image is obtained.

[0115] Through this solution, regions affected by light refraction and / or light reflection are identified. These regions result in a decline in image quality due to the unevenness of light. Determining these regions helps to perform image adjustment targeted. By enhancing the contrast of the regions affected by light and shadow, the difference between the object and the background becomes more obvious, which helps with edge detection and detailed recognition work. Through edge detection and image segmentation techniques, the edges and details of the object can be accurately extracted, which helps to identify the shape and position of the object. Based on the information of the object edges and details, the surveillance image is adjusted to eliminate the errors caused by uneven light, improving the clarity and accuracy of the image.
