The invention discloses a single-camera four-lane vehicle high beam detection device based on a vertical narrow slit, and belongs to the field of traffic transportation signal control equipment. The device mainly solves the problem that a traditional single-phase (image) machine vehicle high beam detection device can only track three-lane vehicles with high beams turned on and cannot effectively track four-lane vehicles with high beams turned on. The device is characterized in that a traditional camera is mounted on a two-position type rotating platform and directly faces lanes 1-3, a vehicle high beam light daylighting unit having a built-in photosensitive element and engraved with a vertical narrow slit is additionally mounted at the position directly facing a lane 4, and when a vehicle with a high beam turned on passes through the lane 4, the daylighting unit receives light of the high beam through the vertical narrow slit and irradiates the built-in photosensitive element,and stray light interference of other lanes is eliminated. When the intensity of light irradiating the photosensitive element exceeds a preset value, the rotating platform is rotated through a controller, the direction of the traditional camera is adjusted, license plate numbers of coming vehicles on the lane 4 are shot, and the original position is restored after shooting is completed. The device has the characteristics of low cost, easiness in implementation, convenience in maintenance and the like.

    本发明公开了一种基于竖向窄缝的单相机四车道车辆远光灯检测装置,属交通运输信号控制设备领域。此装置主要解决传统单相(像)机车辆远光灯检测装置只能追踪三车道车辆,不能有效追踪四车道车辆开远光灯的问题。包括把传统相机安装在两位式旋转平台上,正对1‑3车道,在正对4车道处加装一个刻有竖向窄缝的、内置光敏元件的车辆远光灯光采光单元,当4车道有开远光灯车辆通过时,采光单元通过竖向窄缝接受远光灯光线照射到内置光敏元件上,并排除其他车道杂光干扰。当照射到光敏元件上的光强超过预设值时,通过控制器转动旋转平台,调整传统相机方向,拍摄4车道来车车牌号,完成后恢复原位。此装置具有成本低、易于实现、便于维护等特点。
