Abstract: Apparatus and methods for determining an atmospheric condition in an environment of a vehicle are described herein. A long wave infrared camera may be used to produce thermal image data from a field of view of the LWIR camera that includes an unknown atmospheric condition. The thermal image data may include a characteristic that may be compared to characteristic of thermal image data for a known atmospheric condition. A result of the comparison may be used to make a determination related to the unknown atmospheric condition which may be used in controlling the vehicle.

Abstract: A wind tunnel test may be performed on a vehicle to determine accumulation of substances (e.g., water) on sensors of the vehicle. Control surfaces may be created for the sensors based images representing the accumulations, where the control surfaces represent the include obstructions located where accumulations were detected during the test. The vehicle may then navigate around an environment using the control surfaces in order to determine a drivability of the vehicle. Also, a simulation may be performed, where the simulation outputs images representing simulated accumulations on the sensors. The outputs from the simulation may be compared to the results from the test in order to determine how accurately the simulation represents the test, determine domains in which the vehicle may safely operate, and/or improve the simulation.

Abstract: Techniques associated with generating or tuning parameters associated with long wave infrared sensor data to improve object detection associated with the captured images are discussed herein. The system may determine a region of interest associated with the sensor data and adjust or tune the parameters to improve detection(s) within the region of interest. Additionally, the system may adjust the parameters based on map data and/or environmental conditions, such as weather and temperature.
