Embodiment 1

[0048] Such as figure 1It is a flow chart of the method for determining the traffic condition of a lane in Embodiment 1 of the present invention, and this embodiment can be applied to a system using radar as a measuring device.

[0049] Embodiment 1 steps are as follows:

[0050] S110. Obtain monitoring data of the radar set according to the preset direction.

[0051] In the system using radar as the measuring device in this embodiment, it is placed according to the preset direction, and it is placed on the side of the road to collect data from one side to the other. The radar is always in the data collection state, and the collected raw data Stored in the radar's own buffer area, the required raw data will be read from the radar in subsequent use, but the raw data is messy and needs to be preprocessed before it can be used, so the subsequent use is to suppress the clutter of the raw data Monitoring data obtained after data preprocessing operations such as frequency mixing a...

Embodiment 2

[0067] Embodiment 2 of the present invention further supplements part of the content on the basis of Embodiment 1, specifically as follows:

[0068] Such as figure 2 As shown, in step S140, determining the lane driving conditions according to the connected domains on the binarized image specifically includes:

[0069] S141. Determine the ordinate of the centroid of each connected domain, and determine the corresponding lane of the vehicle according to the ordinate of the centroid.

[0070] In this embodiment, each connected domain represents a vehicle, and the ordinate represents the distance. Each vehicle is in a different position on the binarized image. The position of the corresponding vehicle can be estimated by analyzing the centroid ordinate of the connected domain. , the lane to which each vehicle belongs can be specifically obtained according to different distances, and the driving conditions of the lane can be obtained after the specific lane is divided.

Embodiment 3

[0081] Figure 4 A device 300 for determining the traffic condition of a lane provided in Embodiment 5 of the present invention is applied to equipment, and specifically includes the following modules:

[0082] The data acquisition module 310 is configured to acquire the monitoring data of the radar set according to the preset direction.

[0083] An image synthesis module 320, configured to synthesize distance-time images according to the monitoring data.

[0084] The connected domain determining module 330 is configured to perform binarization on the distance-time image to obtain a binarized image and determine the connected domain.

[0085]The analysis module 340 is configured to determine the lane traffic conditions according to the connected domains on the binarized image, and the lane traffic conditions include traffic volume and lane time occupancy rate.

[0086] More specifically, the data acquisition module 310 includes:

[0087] The original data acquisition unit i...

Abstract

The embodiment of the invention discloses a method, device, equipment and storage medium for determining the driving condition of a lane. The method specifically includes: acquiring monitoring data of a radar set according to a preset direction; synthesizing a distance-time image according to the monitoring data; performing binarization on the distance-time image to obtain a binarized image and determining a connected domain; according to the binarized image The connected domain above determines the traffic condition of the lane, which includes the traffic flow and the time occupancy rate of the lane. The method is based on radar for monitoring, and the difficulty and cost of installation and maintenance are low, and it can be portable and mobile without hindering traffic, and it is not affected by the weather when in use.

Description

technical field [0001] The present invention relates to the field of traffic, in particular to a method, device, equipment and storage medium for determining and transmitting lane driving conditions. Background technique [0002] The number of cars owned in China is increasing year by year. At present, the number of privately owned cars in China exceeds 200 million, and the upward trend is still maintained. It is estimated that the number of privately owned cars will reach 300 million in a few years. A large number of privately owned cars will inevitably bring about traffic congestion and other problems. At present, traffic management departments mainly adopt three methods to solve traffic problems: strengthening road infrastructure, limiting the number of private cars on the road, and developing intelligent traffic systems. [0003] Effective traffic planning and advanced intelligent transportation systems are inseparable from the collection and processing of traffic data. ...
