Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of traffic flow monitoring, and in particular relates to a traffic intersection flow monitoring device. Background Art
[0002] Traffic flow monitoring can be divided into two categories according to the method: manual and automatic instrument counting. When observing the road section frequently, the vehicle type is recorded; among them, automatic traffic flow monitoring generally adopts the method of installing a camera at the bottom of the gantry at the intersection, aiming the camera at the lane, taking pictures of the vehicles passing by the camera, and then automatically identifying and counting the photos in the background. However, when installing the camera for traffic flow monitoring, the camera is fixed after installation. Although it can be turned, it is still easy to cause it not to be aimed at the lane or related parts, which will cause the camera to be unable to effectively capture the vehicles or other objects traveling in the lane, resulting in errors in the traffic flow monitoring data. Therefore, a dual-adjustable traffic intersection flow monitoring device with a movable position for the monitoring camera is proposed. Utility Model Content
