| titleOfInvention | Method and device for extracting center of laser stripe of steel rail outline in dynamic driving environment |
| abstract | The invention provides a method and a device for extracting the center of a laser stripe of a steel rail outline in a dynamic driving environment, wherein the method comprises the following steps: inputting a laser stripe image of the steel rail outline to be extracted into a deep learning network structure segmentation model, and segmenting the light stripe image into a plurality of sub-region images according to the gray scale characteristics and the gradient direction characteristics of the light stripe; determining a normal principal direction of each sub-region based on the gradient histogram of the light stripes; each sub-region corresponds to a normal main direction; and constructing a corresponding direction template for each sub-region according to the normal main direction of each sub-region, determining the sub-pixel coordinates of the light strip center of each sub-region according to the direction template, and extracting the sub-pixel coordinates of the laser stripe center of the steel rail profile under the dynamic driving environment according to the sub-pixel coordinates of the light strip center of each sub-region. According to the technical scheme, the efficiency, the accuracy and the robustness of laser stripe center extraction in a dynamic driving environment are improved. |
