Code Comparison

research:

def calc_curvature(v_ego, angle_steers, angle_offset=0):
    deg_to_rad = np.pi/180.
    slip_fator = 0.0014 # slip factor obtained from real data
    steer_ratio = 15.3  # from http://www.edmunds.com/acura/ilx/2016/road-test-specs/
    wheel_base = 2.67   # from http://www.edmunds.com/acura/ilx/2016/sedan/features-specs/

    angle_steers_rad = (angle_steers - angle_offset) * deg_to_rad
    curvature = angle_steers_rad/(steer_ratio * wheel_base * (1. + slip_fator * v_ego**2))

An open autonomous driving platform

Pros of Apollo

  • Comprehensive, production-ready autonomous driving platform
  • Extensive documentation and community support
  • Regular updates and active development

Cons of Apollo

  • Steeper learning curve due to complexity
  • Requires more computational resources
  • Larger codebase, potentially harder to customize

Code Comparison

Apollo (C++):

void Planning::RunOnce(const LocalView& local_view,
                       ADCTrajectory* const trajectory_pb) {
  // Complex planning logic
}

research (Python):

def plan(self, cs, sm):
    # Simpler planning approach
    return self.planner.plan(cs, sm)

Key Differences

  • Apollo: Full-stack solution for autonomous driving
  • research: Focused on research and experimentation
  • Apollo: More structured, enterprise-level approach
  • research: Lightweight, easier to understand and modify

Use Cases

  • Apollo: Suitable for large-scale autonomous vehicle projects
  • research: Ideal for researchers and hobbyists exploring self-driving technology

Community and Support

  • Apollo: Large community, corporate backing
  • research: Smaller community, more DIY-oriented

Both projects contribute significantly to autonomous driving technology, with Apollo offering a more comprehensive solution and research providing a simpler, more accessible approach for experimentation and learning.

Autoware - the world's leading open-source software project for autonomous driving

Pros of Autoware

  • More comprehensive and production-ready autonomous driving stack
  • Larger community and industry support, including ROS integration
  • Extensive documentation and tutorials for easier adoption

Cons of Autoware

  • Higher complexity and steeper learning curve
  • Requires more computational resources and hardware
  • Less focus on end-to-end learning approaches

Code Comparison

research:

def process_model(model, img_in, state_in):
    x = model.forward(img_in, state_in)
    return x

Autoware:

void PlanningNode::run()
{
  rclcpp::Rate rate(config_.update_rate);
  while (rclcpp::ok()) {
    updatePlan();
    rate.sleep();
  }
}

The research code snippet shows a simple model processing function, while the Autoware code demonstrates a more complex planning node implementation in C++, reflecting the differences in scope and complexity between the two projects.

The Udacity open source self-driving car project

Pros of self-driving-car

  • More comprehensive curriculum covering various aspects of autonomous driving
  • Includes real-world datasets and challenges for practical learning
  • Active community engagement and contributions from students and professionals

Cons of self-driving-car

  • Less focused on a specific implementation, which may be overwhelming for beginners
  • Requires more time investment to work through all materials and projects

Code Comparison

research:

def update_status():
    if state == STARTUP:
        # startup procedure
    elif state == DISENGAGED:
        # disengaged behavior
    elif state == ENGAGED:
        # engaged behavior

self-driving-car:

def process_image(image):
    # Preprocess image
    processed = preprocess(image)
    # Detect lane lines
    lanes = detect_lanes(processed)
    # Determine steering angle
    angle = calculate_steering(lanes)
    return angle

The research code focuses on state management for an autonomous system, while the self-driving-car code demonstrates image processing for lane detection and steering control. This reflects the different approaches of the two repositories, with research emphasizing system architecture and self-driving-car focusing on specific autonomous driving tasks.

Open-source simulator for autonomous driving research.

Pros of CARLA

  • More comprehensive and feature-rich simulation environment
  • Active development with regular updates and community support
  • Extensive documentation and tutorials for easier adoption

Cons of CARLA

  • Higher system requirements and more complex setup process
  • Steeper learning curve for beginners
  • Potentially slower execution due to its comprehensive nature

Code Comparison

CARLA example (Python):

import carla

client = carla.Client('localhost', 2000)
world = client.get_world()
blueprint = world.get_blueprint_library().find('vehicle.tesla.model3')
spawn_point = world.get_map().get_spawn_points()[0]
vehicle = world.spawn_actor(blueprint, spawn_point)

commaai/research example (Python):

from selfdrive.car.honda.interface import CarInterface
from selfdrive.controls.lib.drive_helpers import create_event

CI = CarInterface(CP, CarController)
can_sends = CI.apply(CC)

The CARLA code demonstrates setting up a simulation environment and spawning a vehicle, while the commaai/research code shows interfacing with a specific car model and applying control commands. CARLA provides a more generalized simulation framework, while commaai/research focuses on real-world vehicle integration.

Open source simulator for autonomous vehicles built on Unreal Engine / Unity, from Microsoft AI & Research

Pros of AirSim

  • More comprehensive simulation environment for autonomous systems
  • Better documentation and community support
  • Offers photorealistic environments and physics simulation

Cons of AirSim

  • Steeper learning curve due to complexity
  • Requires more computational resources
  • Less focused on real-world driving scenarios

Code Comparison

AirSim (Python API example):

import airsim

client = airsim.MultirotorClient()
client.enableApiControl(True)
client.armDisarm(True)
client.takeoffAsync().join()
client.moveToPositionAsync(-10, 10, -10, 5).join()

research (OpenPilot example):

from selfdrive.car.honda.interface import CarInterface
from selfdrive.controls.lib.longcontrol import LongControl

CI = CarInterface(CP, CarController, CarState)
long_control = LongControl(CP, CI.compute_gb)

Both repositories focus on autonomous systems, but AirSim provides a more general-purpose simulation environment, while research is specifically tailored for real-world driving scenarios. AirSim offers more flexibility and realism in simulations, but research is more directly applicable to on-road autonomous driving development.

Dataset structure

The dataset consists of 10 videos clips of variable size recorded at 20 Hz with a camera mounted on the windshield of an Acura ILX 2016. In parallel to the videos we also recorded some measurements such as car's speed, acceleration, steering angle, GPS coordinates, gyroscope angles. See the full log list here. These measurements are transformed into a uniform 100 Hz time base.

The dataset folder structure is the following:

+-- dataset
|   +-- camera
|   |   +-- 2016-04-21--14-48-08
|   |   ...
|   +-- log
|   |   +-- 2016-04-21--14-48-08
|   |   ...

All the files come in hdf5 format and are named with the time they were recorded. The camera dataset has shape number_frames x 3 x 160 x 320 and uint8 type. One of the log hdf5-datasets is called cam1_ptr and addresses the alignment between camera frames and the other measurements.
