The invention provides a stable real-time laser measurement method based on non-coding parallel multi-line. In the measurement, the data of central pixel points is obtained through light plane constraint and polar line constraint, and central pixel points are matched, and then a three-dimensional model is reconstructed. According to the present invention, the problems of inconvenient carrying and complex operation process of the scanning equipment are solved with the stable real-time laser measurement method, the problem that the single line laser scanning speed is slow is solved in the breakthrough manner by using the parallel multi-line method, the laser strip central pixel point matching precision and the reconstruction efficiency are improved, and by using the filter adding method, the interference caused by the surrounding ambient light is reduced, and the scanning stability and the labeled point recognition rate are improved.
