Project overview
Abto Software was approached by a solution provider delivering innovations to businesses and governments. The company’s main goal is covering regional challenges by providing infrastructure services, business tools, Smart City and IoT solutions.
Our team has joined to assist the organization in designing a bicycle tracking system and improve cyclist safety. The cooperation has resulted in the successful development of a demo solution, which allows to monitor bikers, non-bikers, speed, and even helmets.
Main goals
The project’s main goal was designing a solution for smart cyclist detection by leveraging artificial intelligence. To catalyze technological transformation, the company was pursuing the mission to popularize bicycle culture and construct an efficient cycling infrastructure.
Our team designed an AI based cyclist detection program that:
- Tracks bikers, non-bikers, speed and cycling helmets
- Ensures high recognition and calculation accuracy
How the solution works
We developed a solution, which enables interested parties to collect, store, access, and analyze traffic data. This data includes information about every single cyclist and non-cyclist that enters or exits the track.
This custom AI program can be used to send notifications about bikers not wearing their helmets or speeding. Such control can help drive interest in the cycling culture and improve public safety.
Here’s a step-by-step explanation of the solution’s operation:
1. The camera is placed directly above the track to monitor both bikers and non-bikers that enter and exit that track
2. The video is streamed from camera to workstation equipped with CPU/GPU hardware of sufficient processing power
3. The video is analyzed by the processing unit, which runs the application enhanced with AI algorithm
4. The implemented AI model recognizes bikers, differentiates bikers from non-bikers, captures whether recognized bikers wear helmets or not, and measures their velocity
The system’s features include:
- Biker and non-biker detection
- Cyclist count
- Speed recognition
- Helmet detection
Our contribution
During the solution’s prototyping, we covered:
a. Dataset preparation
At the first stage, to gather traffic information, a camera was placed directly above the multi-lane bicycle track. The camera was capturing both bikers and no-bikers, as well as identifying whether they’re wearing helmets and at which speed they’re moving.
b. Algorithm training in three successive stages:
– Biker and non-biker detection
– Helmet and haircut differentiation
– Speed recognition
Main challenges
During the course of the project, we have faced the following challenges:
- Accessing necessary data sets
Obtaining necessary data sets was troublesome because of some delays on the client’s side.
- Setting equipment
We provided detailed guidance on how to properly install the required equipment, as the company’s employees faced issues adjusting the correct angle and achieving high quality of the final video.
- Choosing the most suitable AI model
Some models we considered are better for accurate speed recognition and others for precise helmet detection. To ensure accurate calculation, our engineers gradually adapted and trained the selected AI model.
- Recognition nuances
The used AI model sometimes confused voluminous hairstyles with helmets, which affected overall precision. For greater recognition accuracy, our team has conducted additional work on training the algorithm.
