摘要： A volume measurement method and apparatus using a depth camera, and a computer-readable medium, are provided. A first depth image of a reference countertop is acquired which includes coordinate and depth data of pixels, the reference countertop adapted for placement of a measured object. The coordinate and depth data are substituted into countertop empirical equations to obtain simulated images. Each of the countertop empirical equations represent a height variation pattern of the reference countertop. A correlation between each of the simulated images and the first depth image is calculated. A simulated image with the highest correlation is used as a target image of the reference countertop. A countertop height of the reference countertop is obtained based on the target image, a height of the measured object is calculated using the countertop height, and a volume of the measured object is calculated using the height. These disclosures improve accuracy of object volume measurement.

摘要： A method for operating a measurement device using a blockchain. A blockchain system comprises a lease platform node or lease platform node device, a lessor client, and a lessee client. Existing state information about the measurement device is stored in the blockchain. The method can include receiving a lease order for the measurement device that is sent by a lessee client, sending a lease notification based on the measurement device to the lessor client to notify the lessor to send the measurement device to the lessee, receiving, after the lessee receives the measurement device sent by the lessor, a device state detection request sent by the lessee client or the measurement device, wherein the device state detection request comprises first current state information about the measurement device, and detecting whether the first current state information matches the existing state information, and if yes, creating a lease contract for the measurement device.

摘要： A calibration device is provided for a weighing system that has a tank with a plurality of support legs at a lower part thereof. The calibration device has at least one calibration module, a hydraulic system and a calibration terminal. An upper end of each calibration module is connected to an upper part of a corresponding support leg. A lower end of each calibration module is fixed to a foundation. A hose connects each calibration module to the hydraulic system for applying a force to the tank. The calibration terminal, connected to each calibration module, displays in real-time, the force applied to the tank. The calibration device can greatly improve the production efficiency, and in use, takes only two hours to complete the calibration, which is faster than the test weight and other calibration methods.

摘要： Accurate weighing and measurement of fine materials is provided by a linear compensation apparatus and a weighing system. The linear compensation apparatus has a weight loading mechanism (10) with a bearing plate (11), a drive apparatus (12), and a measuring weight (13). The drive apparatus is mounted onto the bearing plate, the measuring weight is connected to the drive apparatus, and, by hoisting or lowering the measuring weight with the drive apparatus, loads from the bearing plate are adjusted. The linear compensation apparatus and the weighing system greatly reduce device costs and labor costs in a batching process, save time and effort, have no risk of cross-contamination, and achieve automated production operation.

摘要： A method and a system measure interfering influences on a checkweighing device. In the method, external interference data are obtained, as are interference data from the checkweighing device itself and interference data from an object being weighed, by calculating or mapping the weighing error data in the stationary state, in the operating state, and in the weighing state. The system for measuring the interference uses a meter and a processing apparatus. The meter and the processing apparatus perform an interference measurement and a compensation method. The amount of interference in the checkweighing device in each state and the amount of influence of the interference on the weighing performance is obtained, thereby facilitating the production, debugging, maintenance, and use of a checkweighing device.

摘要： Methods and systems for eccentric load error correction are disclosed. A plurality of weighing data sets for a weight having a mass value are obtained, where the weight is loaded at different positions on a weighing platform of a weighing device. Differences between each of the weighing data sets and the average value of the plurality of weighing data sets or the mass value of the weight are calculated. Sensor correction coefficients are calculated and updated when the maximum absolute value of the differences exceeds a pre-set threshold. The weighing data sets are updated. The above steps are repeated until the absolute values of all the differences are less than the pre-set threshold.

摘要： An integrated high-precision weighing module has a shell, an electromagnetic force sensor, a printed circuit board (PCB), a weighing pan component, a support ring, and an air baffle ring. The electromagnetic force sensor and the PCB are mounted in the shell. A bearing head of the electromagnetic force sensor extends upward from an upper end portion of the shell. The support ring sheathes the bearing head. The weighing pan component is mounted on the bearing head, with the support ring located between the weighing pan component and the shell. The air baffle ring is disposed around the weighing pan component and located on the support ring. A first airflow channel is formed among the shell, the support ring, and the air baffle ring. At least part of airflow in the shell flows to the outside through the first airflow channel.
