Abstract
A system can have an electromagnetic radiation (EMR) detection and ranging (DAR) device, such as a LIDAR device. A shock mount can couple the EMR DAR device to a vehicle. The shock mount can isolate the EMR DAR device from impulse shocks experienced by the vehicle. An inertial measurement unit (IMU) can be coupled to the EMR DAR device or a first portion of the shock mount. The IMU can measure movement of the EMR DAR device. Alternatively or additionally, the EMR DAR can detect locations of a reference feature of the vehicle at different times and can use the detected locations to determine movement of the EMR DAR relative to the vehicle. Data of the EMR DAR device indicative of detected features can be adjusted based at least in part on the movement measured by the IMU.
