The invention discloses a rapid continuous profile detection method based on linear structure laser, and belongs to the field of steel rail protection. The method specifically comprises the following steps: firstly, setting initial line parameters for a to-be-detected track; newly establishing a detection project according to the line ledger data of the track to be detected, and importing project data; then, a linear structure laser acquisition device is built by taking the rail trolley as a carrying platform, and real-time data acquisition is performed on the to-be-detected rail; transmitting the data to an embedded computer for analysis, and extracting feature points; splicing the original point clouds of the plurality of sensors together by using the calibrated deflection angle, and combining the original point clouds into profile data containing complete steel rail point clouds; finally, the profile data collected each time are written into a database in a coordinate format in real time, and later profile display and periodic steel rail profile management are facilitated. The device can be carried on a rail car and a detection vehicle and can adapt to high and low speed environments, and the encoder is used for signal triggering, so that the reliability and the stability of data are improved; the detection efficiency is high.
