Title:
LOAD VOLUME RATIO CALCULATION DEVICE, LOAD VOLUME RATIO CALCULATION METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/047986
Kind Code:
A1
Abstract:
The present invention provides a load volume ratio calculation device comprising: a first depth image acquisition unit that acquires a first depth image taken by a sensor when no cargo is loaded in a cargo room, the first depth image indicating the distance from the sensor to a blocking object which is inside the cargo room and opposes the sensor; a first volume calculation unit that calculates a first volume on the basis of the first depth image, the first volume being the volume of a free space in the cargo room when no cargo is loaded in the cargo room; a second depth image acquisition unit that acquires a second depth image taken by the sensor when a cargo is loaded in the cargo room, the second depth image indicating the distance from the sensor to an blocking object which is inside the cargo room and opposes the sensor; a second volume calculation unit that calculates a second volume on the basis of the second depth image, the second volume being the volume of the free space in the cargo room when the cargo is loaded in the cargo room; and a load volume ratio calculation unit that calculates a load volume ratio being the ratio of a volume occupied by the cargo loaded in the cargo room to the first volume on the basis of the first volume and the second volume.
