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.

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.

Abstract: An AGV navigation device is provided, which includes a RGB-D camera, a plurality of sensors and a processor. When an AGV moves along a target route having a plurality of paths, the RGB-D camera captures the depth and color image data of each path. The sensors (including an IMU and a rotary encoder) record the acceleration, the moving speed, the direction, the rotation angle and the moving distance of the AGV moving along each path. The processor generates training data according to the depth image data, the color image data, the accelerations, the moving speeds, the directions, the moving distances and the rotation angles, and inputs the training data into a machine learning model for deep learning in order to generate a training result. Therefore, the AGV navigation device can realize automatic navigation for AGVs without any positioning technology, so can reduce the cost of automatic navigation technologies.

Abstract: An automatic guided vehicle positioning system includes one or more positioning areas and an automatic guided vehicle. The positioning areas each have a positioning pattern. The automatic guided vehicle includes a beam emitter, a beam receiver, and a processor. The beam emitter is configured to emit a light beam to scan the positioning areas. The beam receiver is configured to be spaced apart from the beam emitter by a specific distance, wherein the beam receiver receives the light beam scattered by an area other than the corresponding positioning pattern of the positioning areas and does not receive the light beam retroreflected by the corresponding positioning pattern. The processor is configured to recognize the corresponding positioning pattern based on the light beam received by the beam receiver and the retroreflected light beam not received by the beam receiver and to position the automatic guided vehicle.
