Abstract:The line structured light vision measurement technology is widely used as a non-contact measurement technology. This paper proposes a method for structured light vision measurement calibration based on the drawing method by analyzing the mathematical model of the visual measurement sensor and using the feature point constructed on the light plane. This method has simple process and reduces the cost of calibration equipment, laying the foundation for line structured light engineering application. The calibration results show that the method meets the measurement requirements.
