Automatic driving scenario with ADAS ANNOTATION

In Automated Driver Toolbox TM, The driving scenario object and driving Scenario Designer app are effective devices for creating simulated operating scenarios. You can construct your road network, or import one downloaded from open DRIVE and HERE HD Live Map or OpenStreetMap. Adding actors and vehicles to build driving scenarios and then defining their paths is possible. The waypoints that will generate the trajectories need to be selected, so vehicles' trajectories lie inside the roadway network and cars don't meet as they move along their paths. Defining these vehicle positions and courses often requires multiple trials, which can be time-consuming when dealing with huge roads and various vehicles to arrange.

This scenario includes assist functions and illustrates how to utilize the object for driving strategies and to automate the placement of vehicles and the generation of a trajectory. You can import the generated scenario into the Driving Scenario Designer app. The rest of the design illustrates the processes involved in automating the generation of strategies.

Import road map. Utilize aiderOSMimport to add the OpenStreetMap road network into the driving scenario object.

Define start and goal positions - Using the helper function helperSamplePositions, specify regions of interest (ROIs) in the road network to select the start and goal positions for vehicles.

Create vehicle trajectories. Utilize the helper functions helperGenerate waypoints and course to create waypoints and circuits.

Change speed profile to prevent collisionsModify the speed profiles when using the Simulink Collision Free Speed Manipulator simulation scenario. The model analyzes every vehicle's speed profile and prevents collisions while they travel along their respective trajectories. The model's output is an up-to-date scenario free of collisions between cars. Using the helper function to help get CFSMScenario, you can convert the output of the CollisionFreeSpeedManipulator Simulink model to a driving scenario object.

In reducing human error, ADAS can help make roads more secure. Specific ADAS systems help to promote safe driving by alerting drivers of potentially dangerous road conditions, such as when a vehicle within the driver's blind spot could make changing lanes difficult. Others ADAS systems, for instance, collision avoidance and autonomous emergency brakes, automatism driving behaviour.

Determine the beginning and finishing points.

To develop a driving scene, begin by identifying particular points in the road network which could use as the starting and ending points for vehicles within the scenario. Utilize the assister Sample Positions function to create random sets of these locations in the roadway network. You can set the goal's positions and start in various ways, using any or all of the name-value pair arguments in the Helper Sample Positions functions. "

Set the settings for the random generator to generate random points using "Seed." As for the goal and start locations, you can select any of the issues in the set generated.

You can specify at least one ROI within the road network to establish the point of departure.

ADAS ANNOTATION

Per the Society of Automotive Engineers, there are five levels of driver automation. Most cars on the road today feature ADAS features that range from Level 0 up to Level 3. Organizations have pushed levels 4 and 5 to the top in automated vehicles.

How Do ADAS Features Work Design?

Let's examine the adaptive cruise control feature as an illustration, to show what ADAS features will create. If it is activated, this ADAS feature will turn on. It slows the vehicle when it comes up to a car in front and then accelerates to cruising as soon as the vehicle ahead can move a safe distance.

The first step in developing the adaptive cruise controller (ACC) will be gathering information from sensors that will mount within the automobile. A camera and a radar sensor are essential to enable adaptive cruise control. The camera can detect other objects within the picture (such as a car walking, a pedestrian, a tree, and others), and the radar determines the distance between our vehicle with the other object. All of these process needs quality Image Data Collection.

We concentrate on ADAS algorithm development after collecting information via our cameras. Many types are adaptive cruise control.

Three stages:

  •  Algorithm for the perception that determines whether or not there's any vehicle ahead of us.
  • A radar algorithm is employed to calculate our distance to the car.
  • The algorithm for controlling our car's speed is according to distance measurements.

We utilized ACC as an illustration for the ADAS feature. However, the general method of selecting suitable sensors and constructing algorithms using sensor data applies to every ADAS feature.

Sensors Are Important

Camera, radar, and LiDAR are three of the most commonly used sensor types to implement ADAS features.

Cameras are employed to aid in ADAS detection tasks. Blind spots can identify by cameras mounted on a car's sides. Front-facing cameras can detect traffic, lanes, and pedestrians. Some signs indicate cyclists, pedestrians, and pedestrians. ADAS see algorithms develop by using conventional computer vision and deep-learning algorithms. Cameras offer several advantages:

They are a valuable source of information to aid in the detection of objects. Prices are reasonable so that the process of testing a variety of cameras will be less costly for the manufacturers. There are many options, including fisheye, monocular, and pinhole cameras.

They've received the most incredible attention. The camera is the most seasoned of the three types of sensors that have drawn the most attention. The downside of data from cameras is that it needs to be more appropriate for determining the distance to an object than different types of sensors. Therefore, ADAS developers often mix cameras with radar.

Radar

Radar sensors emit an ultra-high frequency wave that is recorded by the time it is reflected off by the objects around. It could utilize this information to determine the distance between the two places. Radar sensors will use in ADAS, and it locates outside the car.

LiDAR

(light detection and (light detection and) sensors emit the laser and then record when the laser beam returns. The returned signals will transform into a 3D point cloud showing the lidar's surrounding area. The distance between the sensor and the objects within the 3D point will determine by LiDAR data.
