Visual-Inertial Odometry on Chip: An Algorithm-and-Hardware Co-design Approach

Abstract: Abstract-Autonomous navigation of miniaturized robots (e.g., nano/pico aerial vehicles) is currently a grand challenge for robotics research, due to the need for processing a large amount of sensor data (e.g., camera frames) with limited on-board computational resources. In this paper we focus on the design of a visual-inertial odometry (VIO) system in which the robot estimates its ego-motion (and a landmark-based map) from onboard camera and IMU data. We argue that scaling down VIO to miniaturized platforms (… Show more

“…• Persistent localization: While current VINS are able to provide accurate 3D motion tracking, but, in smallscale friendly environments, they are not robust enough for long-term, large-scale, safety-critical deployments, e.g., autonomous driving, in part due to resource constraints [95,97,164]. As such, it is demanding to enable persistent VINS even in challenging conditions (such as bad lighting and motions), e.g., by efficiently integrating loop closures or building and utilizing novel maps.…”

“…For the design space of the "computation", we actually considered the joint selection of the computing board and the visual-inertial navigation (VIN) algorithm used for state estimation. Considering them as a single component has the advantage of allowing the use of statistics reported in other papers, e.g., stating that a VIN algorithm runs at a given framerate on a given computer [1]. Therefore our modules are M .…”

“…Recent advances in sensor design and rapid prototyping are enabling the manufacturing of low-cost robots with advanced sensing and perception capabilities. For instance, one can implement high-precision visual-inertial navigation with inexpensive camera and MEMS inertial measurement units [1]. Similarly, modern embedded CPU-GPU [2] offer high-performance computing in a compact form-factor and at a relatively affordable cost.…”

“…1, right). Exploring the co-design space between VO (with inertial) algorithm and hardware illuminates parametric settings that improve VO output [11]. Building more efficient VO/VSLAM algorithms, in parallel with better hardware integration, is important to realizing the goal of accurate, low-latency VSLAM.…”
