Embodiment 1

[0026] This embodiment provides a road vehicle type identification method, which can be used to monitor passing vehicles on the road to identify the type of passing vehicles, such as figure 1 As shown, the method includes:

[0027] Step 1: Install the distance measuring device above the lane of the road; generally, the distance measuring device is set directly above the lane;

[0028] Step 2: The distance measuring device transmits a distance measuring signal to the lane at a certain frequency to monitor the vehicles passing through the lane, and under the influence of the shape of the passing vehicle, the monitoring device monitors and obtains a plurality of monitoring points of distance changes;

[0029] Step 3: Form the shape features of the passing vehicle through the obtained multiple monitoring points, and match the formed vehicle shape features with various stored basic vehicle shape features, so as to identify the type of the passing vehicle.

[0030] In step 2 of the...

Embodiment 2

[0034] This embodiment 2 provides a road vehicle type identification system, which can be used to implement the method given in the above embodiment 1, such as Figure 6 As shown, the system includes:

[0035] distance measuring device 71 and identification processing device 72;

[0036] Wherein, the distance measuring device 71 is communicatively connected with the identification processing device 72, and is installed above the lane of the road when in use, and is used to transmit a distance measuring signal to the lane at a certain frequency to monitor vehicles passing through the lane, Under the influence of the shape of the passing vehicle, the monitoring device monitors and obtains a plurality of monitoring points with distance changes, and transmits the obtained monitoring points to the recognition processing device 72;

[0037] The recognition processing device 72 is used to form the appearance characteristics of the passing vehicle through the multiple monitoring poin...

Abstract

The invention discloses a road vehicle type identification method and a system thereof, belonging to the technical field of identification. The method comprises the steps: a distance measuring deviceis arranged above the driveway of the road; the distance measuring device transmits distance measuring signals to the driveway according to a certain frequency to monitor the vehicle passing through the driveway, and a monitoring device obtains a plurality of monitoring points with distance change by monitoring under the influence of the passed vehicle appearance; and the appearance features of the vehicle passing by are formed by the obtained monitoring points, and the formed appearance features of the vehicle and the stored basic appearance features of all the types of the vehicles are matched so as to identify the type of the vehicle passing by. The vehicle type identification method has higher monitoring reliability, can comparably accurately identify the type of the vehicle passing byand provide accurate monitoring data for the road monitoring, can realize 24-hour monitoring and not be influenced by light and climate change, and can transform the monitoring facility in the existing traffic roads with lower transform cost.

Description

technical field [0001] The invention relates to the technical field of identification, in particular to a road vehicle type identification method and system. Background technique [0002] When vehicles pass, identifying the type of passing vehicles is of great help to improve road management. At this stage, the road vehicle detection in our country is generally: place an induction probe directly above the road, and count the vehicles by the electromagnetic changes generated when the car passes, so as to monitor the traffic flow. However, this monitoring method can only count the number of vehicles, and cannot distinguish the types of vehicles passing through the monitoring point, which greatly reduces the effectiveness of monitoring data. Contents of the invention [0003] Based on the above-mentioned problems in the prior art, an embodiment of the present invention provides a road vehicle type identification method and system, which can effectively identify the type of p...
