Problems solved by technology

[0004] There are multiple detection methods for the number of people in the prior art, for example, the monitoring method for the number of passengers in a vehicle and the method for monitoring the number of passengers in a vehicle and the computer-readable recording medium (201310289617.5) provide the detection of the number of people in a vehicle through an imaging device and image processing. However, when the monitoring method is applied to the detection of the number of passengers in vehicles on the HOV lane, it is easy to cause the number of passengers detected by image processing to be less than the actual number of passengers due to the occlusion of the front passengers, resulting in misjudgment

Embodiment Construction

[0034] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0035] refer to figure 1 , a method for detecting the number of vehicle passengers in a HOV lane, comprising the following steps:

[0036] A. Send a trigger signal when a vehicle is detected to pass by the trigger shooting module set in the HOV lane;

[0037] B. After receiving the trigger signal, the front camera module and the side camera module shoot the front and side of the passing vehicle at the same time;

[0038] C. The front camera module and the side camera module send the captured image data to the control module, and the control module processes the captured image data to calculate vehicle features and the number of passengers;

[0039] D. The control module judges the vehicle behavior according to the calculated vehicle characteristics and the number of passengers.

[0040] The triggering shooting module, the front shooting module ...

Abstract

The invention discloses an HOV lane vehicle passenger number detection method and device. The method comprises the following steps: when a vehicle passes, triggering a control module to start a frontshooting module and a side shooting module to simultaneously shoot the front face and the side face of the passing vehicle respectively; sending the shot picture data to the control module for processing and calculating vehicle features and the number of passengers; and through the control module, carrying out vehicle behavior judgment according to the obtained vehicle features and the number of passengers. By shooting the front and side faces of the vehicle on an HOV lane, the case that the detected number of passengers is smaller than actual number of passengers due to shielding of front passengers when only the front face is shot is prevented, so that accuracy of the detection result is ensured; through a short-wave infrared shooting device, capability of imaging through side windows ofthe vehicle is realized; and the device and method have the advantages of day-night imaging, no need of refrigeration and being harmless to human eyes. The HOV lane vehicle passenger number detectionmethod and device can be widely applied to the traffic control field.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and a device for detecting the number of vehicle passengers in an HOV lane. Background technique [0002] HOV (High Occupancy Vehiclelane) lane is a special lane for vehicles with at least a certain number of passengers, also known as a high-capacity lane. Vehicles that can use this type of lane include buses, cars or trucks with more than 2 people . [0003] HOV lanes can effectively improve the utilization of road space. However, in reality, some vehicles are lucky. Although the number of passengers does not meet the requirements, they still use HOV lanes, which affects the efficient application of HOV lanes. Therefore, the enforcement of HOV lanes is very important, which can effectively reduce the phenomenon of HOV occupation. [0004] There are multiple detection methods for the number of people in the prior art, for example, the monitoring method for the...
