Abstract: An object is to enable accurate detection of an erroneous distance measurement result. An information processing device according to the present technology includes a processing unit that performs processing using a machine-learned learning model on at least a part of first distance measurement information acquired by a first sensor, and outputs second distance measurement information after being subjected to correction of a correction target pixel included in the first distance measurement information, the processing including: first processing of correcting the correction target pixel using the first distance measurement information including the correction target pixel and image information acquired by a second sensor as inputs; and second processing of outputting the second distance measurement information.

Abstract: Provided is a method for enabling recovery of metal element leaching capacity of a deep eutectic solvent used for leaching a metal element from an ore containing the metal element. A method for recycling a hydrophobic deep eutectic solvent disclosed here includes: preparing a hydrophobic deep eutectic solvent used for leaching a metal element from an ore containing the metal element; and bringing the hydrophobic deep eutectic solvent and hydrochloric acid into contact with each other. In the hydrophobic deep eutectic solvent, a hydrogen bond donor is a carboxy group-containing compound, and a hydrogen bond acceptor is chloride salt. The amount of use of the hydrochloric acid is such that hydrogen chloride is 1 mole or more with respect to 1 mole of the hydrogen bond acceptor.
