We employ high-resolution collection equipment to acquire precise point cloud data, as illustrated in Figure 1. The collection equipment comprises four LJ-X8020s, a dual-axis displacement mechanism, and a movable placement platform. Four LJ-X8020s are fixed below the dual-axis displacement mechanism through sheet metal connectors, and the dual-axis displacement mechanism is fixed to the movable placement platform by four adjustable height brackets. What's more, the control system of the collection equipment is integrated into the movable placement platform. Four LJ-X8020s, driven by a dual-axis displacement mechanism, start scanning from a particular corner of the sample and move in a zigzag pattern along the platform until it covers all the planes of the sample.
To ensure the authenticity of the data, both ceramic package substrate samples of CPS3D-Seg are all from actual production lines. What's more, we collected 20 different types of products to ensure data diversity.
CPS3D-Seg has the best resolution and precision. Meanwhile, the point number of ours is also the highest. Our point cloud number is calculated after reduction, which means that the original point cloud data is higher than the current statistical value. What's more, the object category of CPS3D-Seg is the second best among several datasets.
