Abstract
A sensor having a positive temperature coefficient shroud is described, as well as a computing system to control actuation of the positive temperature coefficient shroud. According to one example, the computing system executes a method that actuates the positive temperature coefficient shroud of the sensor based on a transmittance parameter of the sensor.
Claims19
A system, comprising:
- a processor;
- and
- memory storing instructions, executable by the processor, that comprise, to:
- receive, from a sensor coupled to the processor, an image;
- determine a transmittance parameter of the image;
- and
- when the transmittance parameter is less than a transmittance threshold value, then actuate a positive temperature coefficient (PTC) shroud of the sensor, wherein the transmittance threshold value is based on a set of noise values and a set of error values.
4 more elements
A method, comprising:
- storing a transmittance threshold value in memory, wherein the transmittance threshold value is associated with autonomous vehicle operation;
- determining to actuate a positive temperature coefficient (PTC) shroud of a sensor when a transmittance parameter is less than the transmittance threshold value;
- and
- actuating the PTC shroud based on a transmittance parameter of the sensor.
1 more element
A method, comprising:
- for an image of a sensor comprising a positive temperature coefficient (PTC) shroud, determining a signal-to-noise (SNR) value, a peak SNR (PSNR) value, a root mean square error (RMSE) value, and a mean absolute error (MAE) value;
- and
- based on the SNR, PSNR, RMSE, and MAE values, actuating the PTC shroud.
