This application discloses a method, apparatus, storage medium, and electronic device for determining road debris. The method includes: acquiring a real-time video stream of a target road surface; performing inference and recognition on the real-time video stream using a small model to obtain a recognition result; extracting a set of video frames containing suspicious targets from the real-time video stream based on the recognition result; synchronizing the video frame set to a large model for review processing; and determining the presence information of road debris on the target road surface based on the review result. This application solves the problem that small models with high real-time performance may have a high false alarm rate due to limitations in feature extraction when detecting road debris, while large models with high accuracy can identify debris more precisely, but are difficult to implement in real-time due to high computational resource consumption. Therefore, this method improves the efficiency and accuracy of road debris detection, achieves real-time debris detection, timely warnings, and effectively reduces the risk of traffic accidents caused by road debris.

This invention provides a method, device, electronic device, and storage medium for identifying road debris, belonging to the field of signal processing technology. The method includes: acquiring the original vibration signals corresponding to multiple grating measuring points in a grating array vibration sensing optical cable deployed on the road; determining a first energy for each grating measuring point within a first time window based on the original vibration signal; determining the occurrence time of a debris event within the first time window based on the first energy of each grating measuring point; determining a second energy for each grating measuring point within a second time window, wherein the occurrence time falls within the second time window; and determining the location of the debris on the road based on the second energy. Because the location of the debris is determined based on the energy distribution of multiple grating measuring points within a precise time window, the possibility of false alarms and missed alarms is reduced, improving the accuracy and efficiency of debris identification.

This invention relates to the fields of intelligent transportation and drone inspection technology, and provides a method and system for highway safety assessment based on drone inspection. The method includes the following steps: acquiring first-view data segments and second-view data segments of a preset road section; registering the first-view data segments with the second-view data segments to obtain a traffic flow map; extracting dynamic features of vehicle surface damage and static distribution features of road debris from the traffic flow map to obtain risk metadata including damage evolution trajectories and spatial coordinates of debris; predicting the structural stability attenuation coefficient of vehicles based on the damage evolution trajectory, and predicting the kinetic potential factor triggering secondary events based on the spatial coordinates of debris, to obtain a dynamic risk assessment result. This invention achieves a quantitative assessment of the dynamic deterioration trend of vehicle damage and the risk of road debris, significantly improving the intelligence level of highway inspection and the ability to prevent secondary accidents.

The application discloses a road litter identification method, device and equipment, and is applied to the technical field of identification, and comprises the following steps: acquiring a first group of scene pictures and a second group of scene pictures of a preset road scene, wherein the first group of scene pictures and the second group of scene pictures both comprise a first scene picture, and the shooting time of the first scene picture is earlier than that of other scene pictures in the first group of scene pictures and the second group of scene pictures; processing the first group of scene pictures and the second group of scene pictures by a pre-trained litter identification model to obtain a first identification result picture and a second identification result picture representing picture changes; and determining whether there is litter in the preset road scene based on the position relationship between the change area in the first identification result picture and the change area in the second identification result picture. The application solves the technical problem of incorrect detection of litter.

The invention relates to the technical field of road surface foreign matter collection, in particular to a vehicle-mounted expressway road surface foreign matter collector which is installed in front of a truck and comprises a collecting hopper, a first oil cylinder, a control assembly, a scraper knife and the like. The cross section of the collecting hopper is trapezoidal, a framework of the collecting hopper is formed by welding section steel pipes, and the surface covering part is composed of thin steel plates and engineering plastics. The first oil cylinder controls the collecting hopper to get close to or away from the pavement. The control assembly is specially used for controlling lifting and lowering of the scraper knife. The scraper knife is of a double-hinge multi-step-layer combined structure and mainly comprises two hinges, an upper scraper knife body and a multi-step-layer lower scraper knife body. The scraper knife is installed at the front end of the collecting hopper through a first hinge. Therefore, the scraper knife is controlled by the control assembly while moving along with the collecting hopper. When fluctuating or small obstacles exist on the road surface, the lower scraper knife rotates around the second hinge shaft and is always kept to be attached to the road surface, the lower scraper knife can achieve self-adaptive obstacle crossing, and manual obstacle crossing can also be achieved through the control assembly. The device has the advantages of light structure and low use cost.

The application belongs to the technical field of intelligent transportation systems, and discloses a road litter detection method, system and device suitable for low-computing-power edge equipment. The video sampling frame is scaled and then input into the detection model, and the two-dimensional boundary box and the category confidence of the suspected road litter are output. The detection model is obtained by embedding an ECA module at the output end of the depth separable convolution module of YOLO Nano. The two-dimensional boundary box is screened, and only the target box with the center point in the preset ROI region and the category confidence greater than the set threshold is reserved as the effective target box. The IoU of the effective target box in different sampling frames is calculated. If the IoU is continuously greater than the set threshold and the maintenance time exceeds the time threshold, it is determined that the target is a static road litter. The key frame of the video is intercepted and labeled, and is sent to the cloud server. The application effectively improves the feature perception ability of small and micro road litter and reduces the small target missing detection rate without increasing the computing power overhead of the edge equipment.
