  • Publication number: 20250052604
    Abstract: A volume measurement method includes: receiving multiple pulse signals when a device under test (DUT) starts passing through a sensing gate; recording multiple X-axis values corresponding to multiple positions of the DUT in response to each pulse signal, and reading the multiple sensing data to calculate a Y-axis value and a Z-axis value corresponding to each X-axis value, wherein the multiple sensing data is obtained by sensing the DUT through the sensing gate; recording a maximum X-axis value corresponding to a final position of the DUT in response to a final pulse signal when the DUT finishes passing through the sensing gate; setting the maximum of the multiple Y-axis values corresponding to the multiple X-axis values as a maximum Y-axis value, and setting the maximum of the multiple Z-axis values corresponding to the multiple X-axis values as a maximum Z-axis value; and calculating a volume of the DUT based on the maximum X-axis value, the maximum Y-axis value and the maximum Z-axis value.

  • Publication number: 20240160211
    Abstract: An automated guided vehicle (AGV) includes an image capturing device, a storage device, a fetching device, a driving device and a processor. The processor is configured to execute: controlling the AGV to move from a starting position to a target position according to a navigation coordinate system, the target position corresponding to the object to be fetched; capturing a depth image from the object to be fetched through the image capturing device; performing image recognition on the depth image to obtain reference pixel information; converting the reference pixel information to the navigation coordinate system according to a coordinate mapping algorithm to obtain a calibrated position; and determining an object-fetching route according to the target position and the calibrated position, and controlling the AGV to move according to the object-fetching route to fetch the object to be fetched.
