Image recognition and bridge monitoring combined ramp loaded vehicle recognition method and system

Abstract

The invention discloses an image recognition and bridge monitoring combined ramp loaded vehicle recognition method and system, and relates to the field of bridges, and the method comprises the steps of obtaining existing ramp video monitoring data, obtaining a vehicle target detector capable of recognizing a vehicle through training, and training an axle number recognizer capable of recognizing the number of axles of the vehicle; identifying a large vehicle passing through the ramp and entering the bridge by using a vehicle target detector to serve as a target vehicle; identifying the axle number of the target vehicle by using an axle number identifier to obtain the axle number of the target vehicle; judging whether the axle number of the target vehicle is greater than a preset threshold value or not, if yes, acquiring bridge monitoring data, judging whether the current load of the bridge exceeds the preset threshold value or not, if yes, recording bridge passage information of the target vehicle, and if not, not processing. Image recognition and bridge monitoring data are combined, and guarantee is provided for long-term healthy and stable operation of the bridge.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a ramp heavy vehicle identification method and system combining image recognition and bridge monitoring. Background technique [0002] Bridges are a key component of transportation. With the gradual advancement of "transportation power", a large number of bridges have emerged. However, some bridge engineering projects have been damaged far before reaching the designed service life. The reason is that overloaded transportation is the main reason. Few are caused by the fatigue strength of the vehicle load, and most of them are caused by overloading. Therefore, it is very important to identify the overweight vehicles on the bridge and analyze its danger for the long-term healthy and stable operation of the bridge. [0003] In the prior art, the vehicle dynamic weighing system is usually used to obtain information such as the weight of the driving vehicle, and the sensor is used to obtain th...

Problems solved by technology

[0003] In the prior art, the vehicle dynamic weighing system is usually used to obtain information such as the weight of the driving vehicle, and the sensor is used to obtain the structural response of the bridge under external loads. However, the above two data are relatively isolated and have not exerted their maximum utilization value.
