In an automated production line, there is a process of product inspection. Generally, the method is divided into the steps of inspecting the production requirements of the processes before the product inspection process; and the quality of the finished product is checked. The purpose of the former inspection is to detect the previous production process and to adjust the production in time. And secondly, correcting subsequent production to improve the yield of finished products. In actual production, it is encountered to detect the relative height between two products or two steps on one product. For such height detection, the height between two measuring surfaces is detected, but since two products or two step surfaces of one product are not in the same plane or the same measuring circle, the height cannot be directly measured by using a caliper or a measuring tool. The conventional measurement method is to select a reference point, measure the height of the two measurement surfaces with the reference point, and calculate the relative height between the two measurement surfaces. However, this method needs two measurements and then performs the calculation, which results in long measurement period and low measurement efficiency. Meanwhile, because each measurement has a measurement error, after the two measurements are carried out and calculation is carried out, the obtained measurement result has the condition of error accumulation, and the measurement result is low in precision. This results in a low yield of the finished product.
