Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0031] Such as figure 2 As shown, the present invention first forms a reference line by fixing the reference point 1 (one point) of the station and the laser direction (one line) emitted by the laser module 3 fixed on it, and the array photoresistor fixed on the measuring point 2 of the target object is displaced The array photoresistors with constant spacing in the sensor 4 are equivalent to setting up a standard scale, and jointly form an independent measurement system. Using the sensitivity of photoresistors to light, when the laser is irradiated on the photoresistor before and after, there is a significant difference in the resistance value of the photoresistor, and the voltage value distributed on all the photoresistors of the array is measured and read through the ADC scanning circuit, and then the resistance value is screened out throu...
