The invention provides a steel rail crawling detection device positioning method based on mathematical model parameter iteration, and the method comprises the steps: obtaining a coarse positioning result of a calibration line, and carrying out the fitting of the coarse positioning result of the calibration line through mathematical model parameter iteration, thereby obtaining an accurate positioning calibration line; obtaining a coarse positioning result of the laser ray, and carrying out mathematical model parameter iterative fitting on the coarse positioning result of the laser ray to obtain an accurate positioning laser ray; according to the accurate positioning calibration line and the accurate positioning laser line, calculating the angle deviation and the position deviation of the two, and rotating the laser module through the system motion control unit to enable the laser line to be parallel to the calibration line and then coincide with the calibration line. According to the portable all-in-one machine, the laser line is adjusted to be consistent with the marker line through translation and rotation, so that the consistency and the installation precision of the portable all-in-one machine can be greatly reduced, the unification of portability and measurement consistency is really realized, the measurement error is remarkably reduced, and the measurement precision is improved.
