Abstract: A parking assistance device performs a process for parking a vehicle in a parking area based on a captured image obtained by an imaging device mounted on the vehicle, and includes a storage part that stores the captured image; a first processing part that detects parking areas present in an imaging area of the imaging device, based on a low-resolution image obtained by reducing the resolution of the captured image; a selecting part that selects a target parking area from the detected parking areas when the parking areas have been detected by the first processing part; an extracting part that extracts an extraction image including the target parking area from the captured image stored in the storage part; and a second processing part that generates, based on the extraction image, target information indicating a target stop location used upon parking the vehicle in the target parking area.

Abstract: The present invention provides a zero emission type method for effective use permitting economical and effective manufacture of zeolite effectively applicable in various sectors of industry by using silicon-containing waste comprising at least one of exhaust gas treatment sludge mainly comprising SiO2 discharged from an optical film manufacturing plant, optical fiber refuse and preform refuse, and aluminum-containing waste comprising at least one of aluminum dross discharged from an aluminum-related manufacturing plant, aluminum dust collection ashes, sludge mainly comprising aluminum hydroxide, cleaning waste liquid of aluminum or an alloy thereof, scrap of metal aluminum or an alloy thereof, and alumina scrap.
