Basic overview: Angle is constructed by two lines, so we measure angle is how to measure two lines. Although the measuring steps of projectors from different manufacturers are different, their principles are very different. Generally, two methods are used, one is to measure the angle value directly by using the angle encoder, the other is to obtain a straight line by taking points and taking at least two points on each line, and form an angle through two straight lines.

The method of measuring the "angle element" of Wanhao Projector is to measure the angle element by measuring the two sides of an angle. The DC3000 system prompts the user step by step to complete the process of collecting sample points on the edges of two lines, constructing angles, and calculating vertices. Each of the two lines can collect 2-50 sample points. When using the random sampling point mode, the number of samples collected on each line is determined by the user. Generally, if you want to measure an angle, you must sample multiple points to measure the line. When using the preset sample point mode, the number of sample points required for measuring each line will be displayed on the LCD screen.
