The invention discloses a road asset detection model construction method and a road asset detection method. The method comprises the following steps: acquiring a road asset image data set; classifying images in the road asset image data set according to target attributes, and inputting a classified image sample set with labels into a preset neural network for training until a road asset detection model meeting conditions is obtained; and performing frame extraction processing on the acquired video stream data to obtain a corresponding road asset image data set, and inputting the road asset image data set into a road asset detection model for training. According to the method, images in an image data set are classified according to target attributes, so that inference of attributes of different labels by a model is facilitated, management and deployment of the model are facilitated, and road asset images can be comprehensively and accurately mastered; and then the trained road asset detection model is utilized to detect the input road asset image data, manual detection is replaced, and the detection efficiency and accuracy are improved.
Description
technical field [0001] The invention relates to the technical field of road asset management, in particular to a road asset detection model construction and a road asset detection method. Background technique [0002] The management of road (highway, railway, etc.) assets includes the detection of road assets and the maintenance of road assets. The traditional method of road asset detection is to use manual inspection, which is not only time-consuming and labor-intensive, but also prone to omissions, and management units cannot comprehensively , Accurately grasp the situation of the road assets owned, and it is impossible to comprehensively and accurately grasp the damage and loss of road assets. With the rapid development of roads and railways, this traditional road asset detection method is showing more and more limitations. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present invention provide a road asset detection model construction and a...
