Abstract
A method and a system for detecting positioning error of a linear moving mechanism are provided, which includes a linear moving mechanism, a moving element, a visual sensor, a calibration object and a data processing system. The vision sensor is fixed on the moving element on the linear moving mechanism and is driven by the moving element to move on the linear moving mechanism. The calibration object is arranged in front of sight line of the visual sensor and used for calibrating posture of the visual sensor. The vision sensor shoots the calibration object at different moving positions on the linear moving mechanism, and the data processing system obtains shooting result, and calculates the coordinate system conversion matrix from the linear moving mechanism coordinate system at moving position point to the preset linear moving mechanism coordinate system, thereby analyzing the positioning error of the linear moving mechanism.
