An effective method which improves the reliability of photoelectic sensor image recognition is analyzed.The methods of environmental light compensation

ways to improve the sensor’s electromagnetic compatibility and other anti-interference measures are studied.By using these measures

the environmental adaptability and working stability of photoelectric sensor are greatly improved.Lagrange interpolation algorithm is applied to improve the resolution of the photoelectric sensor image recognition.Tests and practical applications show that by using the above measures

the sensor has high adaptability

stability and accuracy in different conditions and the maximum measurement error is less than 0.4mm.realizing the high reliability of the photoelectric sensor image recognition.
