Embodiment 1

[0031] A cooperative dynamic speed limit speed measurement system based on visibility detection, including a visibility road environment detection module, a camera, a multi-target radar speed measurement module, a system main control CPU, a power supply system, and a dynamic cooperative early warning display screen,

[0032] The visibility road environment detection module includes array 3DCOMS sensing equipment, naked-eye 3D multi-viewpoint road real-time image acquisition embedded equipment, temperature sensor, humidity sensor, rainfall sensor, pressure sensor, wind sensor, wind direction sensor;

[0033] The visibility road environment detection module, camera, multi-target radar speed measurement module, and dynamic collaborative early warning display are all electrically connected to the system main control CPU, and the visibility road environment detection module, camera, multi-target radar speed measurement module, and system main control CPU , and the dynamic collaborat...

Embodiment 2

[0036] On the basis of Embodiment 1, the naked-eye 3D multi-viewpoint road real-time image collection embedded device includes near-viewpoint stereoscopic image collection components, middle-viewpoint stereoscopic image collection components and far-viewpoint stereoscopic image collection components.

[0037] Through this setting, the three-dimensional images of viewpoints at different distances are collected, and the environmental images of three types of viewpoints, namely near, middle and far, are collected, so as to obtain the visibility of the road environment more accurately.

Abstract

The invention discloses a collaborative dynamic speed limiting and speed measuring system based on visibility detection, belongs to the technical field of road traffic monitoring, and aims to solve the problems that an existing road overspeed illegal photographing system cannot set a proper speed limiting range for illegal photographing according to a road environment, and is poor in flexibility and small in application range. The system comprises a visibility road environment detection module, a camera, a multi-target radar speed measurement module, a system master control CPU, a power supply system and a dynamic cooperative early warning display screen. The visibility road environment detection module comprises array 3DCOMS sensing equipment, naked eye 3D multi-view road real-time image acquisition embedded equipment, a temperature sensor, a humidity sensor, a rainfall sensor, a pressure sensor, a wind power sensor and a wind direction sensor. The invention is suitable for the collaborative dynamic speed-limiting and speed-measuring system based on visibility detection.

Description

technical field [0001] The invention belongs to the technical field of road traffic monitoring, and in particular relates to a cooperative dynamic speed limit speed measurement system based on visibility detection. Background technique [0002] With the continuous development of social economy, my country's road network is also increasingly developed. At the same time, due to the vast territory of our country, the climate and terrain of various regions are quite different, so there are certain changes in the visibility of roads at different locations and at different times. [0003] Existing roads are usually equipped with illegal speeding camera systems, but at this stage, fixed speed limits are set on fixed road sections. Usually, the speed limit ranges set on mountainous and rural roads are lower, and the speed limit ranges on expressways and urban expressways are lower. Relatively high. But at the same place, due to its climate or human influence, its visibility is con...
