Problems solved by technology

However, fixed LiDAR systems usually require a laser for each point in the field of view, thus requiring a large number of lasers to achieve a dense point cloud at a certain distance, which requires a long acquisition time for each frame scan

Embodiment Construction

[0017] The detailed description is merely exemplary in nature and is not intended to limit the disclosure or its application and uses. Furthermore, there is no intention to be bound by any theory presented in the preceding technical background or detailed description. For example, the LiDAR sensor of the present invention has particular application for use in vehicles. However, as will be apparent to those skilled in the art, the LiDAR sensor of the present invention may have other applications.

[0018] Modern vehicles sometimes include various active safety and control systems, such as collision avoidance systems, adaptive cruise control systems, lane keeping systems, lane centering systems, etc., where vehicle technology is evolving towards semi- and fully autonomous vehicles. For example, collision avoidance systems are known in the art that provide automatic vehicle control, such as braking, when a potential or imminent collision with another vehicle or object is detecte...

Abstract

The present application generally relates communications and hazard avoidance within a monitored driving environment. More specifically, the application teaches a system for improved target object detection in a vehicle equipped with a laser detection and ranging LIDAR system by simultaneously transmitting multiple lasers at different wavelengths. The multiple lasers are detected and separated bywavelength in order to decrease acquisition time and / or increase point density.

Description

Background technique [0001] This application relates generally to autonomous and semi-autonomous vehicles. More specifically, the present application teaches an apparatus for improving target object detection in vehicles equipped with a LIDAR system. Background technique [0002] The operation of modern vehicles is becoming more automated, ie able to provide driving control with less and less driver intervention. Vehicle automation has been classified on a numerical scale ranging from zero (corresponding to no automation with full human control) to five (corresponding to full automation with no human control). Various automatic driver assistance systems, such as cruise control, adaptive cruise control, and park assist systems, correspond to lower levels of automation, while truly "driverless" vehicles correspond to higher levels of automation. [0003] Vehicles are increasingly being equipped to autonomously or semi-autonomously determine their surroundings using on-boar...
