Abstract
A region extraction device and a method thereof in a stage previous to detection of a target object, capable of appropriately extracting a region having a possibility of presence of a target object emitting light having a light emission spectrum of a specific narrowband as a determination region in an imaging region, and an object detection apparatus and a method thereof capable of efficiently detecting the target object using a region extraction result are provided. In a region extraction method, a plurality of images including an image of a second narrowband corresponding to a first narrowband of light emitted by a target object and an image of a third narrowband different from the second narrowband are acquired from a multispectral camera. Next, a region that emits light having a light emission spectrum other than a light emission spectrum of the first narrowband is determined as a non-determination region in an imaging region based on the plurality of acquired images, and one or a plurality of regions excluding the non-determination region from the imaging region are extracted as a determination region.
