A kind of Intelligent road traffic monitoring apparatus and system based on binocular camera
Technical field
It the utility model is related to traffic monitoring, and in particular to a kind of Intelligent road traffic monitoring based on binocular camera
Equipment and system.
Background technology
Monitoring is a part essential in traffic administration to road traffic in real time.In the wisdom traffic neck risen in recent years
In domain, road is monitored in real time and the intelligent identification technology based on computer vision algorithms make is tightly combined, and is quickly grown.
The widely used monocular road traffic monitoring system of traditional traffic monitoring video camera, imaged by a monocular
Machine is monitored to road traffic condition.But monocular road traffic monitoring system can not obtain the three-dimensional dimension information of object, clap
Take the photograph that visual field is limited, and be easy in the shooting process of reality to produce very big parallax.
Also have at present and binocular camera is applied in field of road traffic, but existing binocular camera is generally double take the photograph
As head integral structure, when monocular road traffic monitoring system is upgraded into binocular road traffic monitoring system, it is necessary to abandon
Monocular-camera in monocular road traffic monitoring system before, its upgrade cost is high, and can eliminate substantial amounts of monocular-camera,
Cause the wasting of resources.
And during the three-dimensional dimension of object obtains, because the size of visual field has different requirements and calculating parameter to have
It is required that generally require whether to have in same plane the distance between dual camera, the luffing angle of camera, camera
Strict requirements, and the dual camera of this integral structure is used, it can not flexibly realize above-mentioned distance, angle, plane position
The adjustment put.
