establishing a longitudinal reference line passing through the central point of the sub-model 55 of the cellular panel, and judging whether the sub-model 55 of the cellular panel is laid horizontally and the front and back directions are consistent;
establishing a reference plane passing through a longitudinal reference line, and establishing an XY axis coordinate system on the reference plane by taking the central point of the sub-model 55 of the cellular panel as an origin, so that the Y axis of the coordinate system is coincided with the longitudinal reference line, because the sub-model 55 of the cellular panel optimized in the embodiment is a plane, the reference plane is coincided with the sub-model 55 of the cellular panel;
and arranging a grid on the reference plane to assist in measuring the geometric parameters of the sub-model 55 of the cellular panel, wherein the geometric parameters comprise data such as end point coordinates, length, width, included angle of contour lines and the like, so as to obtain processing data of the corresponding cellular panel. The geometric parameters of the sub-model 55 of the cellular panel are obtained by establishing a coordinate system taking the central point of the sub-model 55 of the cellular panel as the origin of coordinates, and the operation is convenient and fast.
