The invention provides a distance measurement method and device based on a laser radar system, and a readable storage medium. The distance measurement method comprises the steps that distance measurement data measured through a plurality of laser radars of the laser radar system are received, wherein the distance measurement data comprise distances between the laser radars and all obstacles withinthe measurement range of the laser radars; a three-dimensional coordinate model is built according to the distance measurement data; and distances between target unmanned driving equipment and the obstacles are determined according to the three-dimensional coordinate model. The three-dimensional coordinate model is built through the distance measurement data measured by the multiple laser radars,the distances between the target unmanned driving equipment and the obstacles are determined according to the three-dimensional coordinate model, and thus compared with the mode that in the prior art, measured distance calibration through a visual image algorithm is conducted by a single laser radar, the distance measurement method can implement measured distance calibration tasks with larger distance ranges, effectively improves the calibration efficiency of the visual image algorithm and effectively increases the accuracy rate of the visual image algorithm.
