Problems solved by technology
[0004] Since the above process is to divide the first data according to the preset position interval, once the second data only includes the vibration data corresponding to the abnormal road section with a small distance, and the preset value is set to a large value, it will not be possible to detect the vibration data. Abnormal road sections, so that the abnormal road sections in the target road cannot be accurately determined

Embodiment Construction
[0028] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the application will be more thoroughly understood, and will fully convey the scope of the application to those skilled in the art.
[0029] In the prior art, the first data of the vehicle running on the target road is obtained, and the first data is divided into at least one group of second data according to the preset position interval, and the divided second data is sent to the Road detection server. After receiving at least one set of second data, the road detection server determines the root mean square corresponding to each set of second data, and when the roo...

The invention provides a road surface anomaly detection method and device, a terminal and a storage medium. The method comprises the following steps: acquiring first data of a vehicle running on a target road, wherein the first data comprises a first vibration acceleration and longitude and latitude corresponding to at least one preset time point within a first duration; according to a preset sliding time window, dividing the first data to obtain at least one group of second data, the second data having at least one abnormal first vibration acceleration, the abnormal first vibration acceleration being a first vibration acceleration not within a preset vibration acceleration range, and the duration of the sliding time window being less than the first duration; and sending the second data to a road detection server, so that the road detection server determines an abnormal road section in the target road according to the longitude and latitude in the second data. The abnormal road section in the target road can be accurately determined.
Description
technical field [0001] The present application relates to the technical field of road surface detection, and in particular, to a method, device, terminal and storage medium for detecting road surface abnormalities. Background technique [0002] With the rapid development of road traffic in my country and the continuous increase of road mileage, how to detect abnormal road surfaces with road damage is of great significance to the safe driving of motor vehicles. [0003] In the prior art, the first data of the vehicle running on the target road is obtained, the first data includes the coordinates of a specific position point and the vibration acceleration corresponding to each position point, and then the first data is obtained according to the preset position interval. It is divided into at least one set of second data, and the at least one set of second data is sent to the road detection server. After receiving at least one set of second data, the road detection server dete...
