Systems and methods of environmental detection for a vehicle
A method for monitoring an environment of a vehicle. The method includes generating, via at least one time-of-flight sensor, at least one point cloud representing the environment of the vehicle, the at least one point cloud including three-dimensional positional information of the environment. The method also includes detecting, via processing circuitry in communication with the at least one time-of-flight sensor, an aerosol in the environment. The method also includes estimating a quality of the aerosol based on at least one feature of the at least one point cloud. The method also includes determining a response condition based on the estimation of the quality. The method also includes communicating an instruction to execute the response condition.

detecting, via a processing circuitry in communication with the at least one time-of-flight sensor, an aerosol in the environment;
estimating a quality of the aerosol based on at least one feature of the at least one point cloud;
determining a response condition based on the estimation of the quality;
communicating an instruction to execute the response condition;
identifying the aerosol in the second point cloud;
comparing the second point cloud to the first point cloud; and
determining an efficiency of an air filter of an air circulation system of the vehicle based on the comparison of the second point cloud to the first point cloud.
2 . The method of claim 1 , further comprising:
receiving an indication of the air circulation system being in a recirculation mode; and
determining an efficiency of the recirculation mode based on the comparison.
3 . The method of claim 2 , further comprising:
determining an open state of a window of the vehicle based on the efficiency of the recirculation mode.
4 . The method of claim 3 , further comprising:
communicating, via a window control system of the vehicle, a control signal to close the window based on the response condition.
5 . The method of claim 4 , further comprising:
adjusting at least one operational parameter of the at least one time-of-flight sensor based on the response condition.
6 . The method of claim 5 , wherein the at least one operational parameter includes at least one of a scanning direction and a scanning frequency, the method further comprising:
controlling at least one of the scanning direction and the scanning frequency.
7 . The method of claim 1 , wherein the quality of the aerosol includes at least one of an identity, a location in the environment, a size of a cloud of the aerosol, a shape of the cloud, a level of light reflectance, a color, a density, a movement, or any combination thereof.
8 . The method of claim 7 , further comprising:
determining a source of the aerosol based on the identity of the aerosol.
9 . The method of claim 8 , further comprising:
determining the level of light reflectance based on the at least one point cloud; and
determining the identity based on the level of light reflectance.

identifying the location based on the at least one point cloud; and
determining a source of the aerosol based on the location.
11 . The method of claim 7 , further comprising:
determining a source of the aerosol based on the movement.
12 . The method of claim 7 , further comprising:
determining a source of the aerosol based on the shape.
