Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional acquisition, in particular to a three-dimensional modeling image acquisition device. Background Art

[0002] Image data acquisition refers to the automatic collection of non-electrical or electrical signals from analog and digital test units such as sensors and other devices under test, and sending them to the host computer for analysis and processing; three-dimensional data acquisition refers to the use of a series of sensors or measuring devices to collect data on three-dimensional objects under test.

[0003] For example, a Chinese utility model patent (CN219282818U) discloses a 3D modeling image acquisition auxiliary device, which states: "In the process of driving the scanner to descend, the scanner can stay for a period of time after descending a certain distance to fully scan the four sides of the model at the same height. After the scanner is driven to descend to the bottom, the model graphics can be successfully acquired at one time, without the need to reciprocate and drive the scanner to rise and fall, thereby improving work efficiency."

[0004] While driving the model to rotate, the above-mentioned device drives the scanner to synchronously descend to scan the four sides of the model at the same height, thereby successfully capturing the model graphics in one go without having to reciprocately drive the scanner to rise and fall. However, when the model is at the same height as the scanner, the scanner can only scan the four sides of the model at the same height, resulting in the scanner being unable to capture the image of the top of the model. Even when the model is lower than the scanner, the horizontal position of the scanner is fixed, resulting in a limited angle for capturing the image of the top of the model. For this reason, the present application proposes a three-dimensional modeling image acquisition device. Utility Model Content
