A position estimation system is a position estimation system for estimating a position of a forklift equipped with a camera and includes: a position estimation unit configured to estimate a position of the forklift on the basis of a feature included in an image captured by the camera; and an inclusion determination unit configured to calculate, on the basis of a position in a height direction of a mast with which the forklift is equipped, an inclusion range indicating a range in which the mast is in the image and determine to stop estimation of the position by using the position estimation unit when the inclusion range calculated exceeds an allowable range.

Pallet detection device that acquires point cloud data indicating a point cloud measured by a two-dimensional distance measurement device on a depth map; detects a straight line corresponding to a front surface of a pallet based on the point cloud in a region presumed to include the front surface of the pallet in the point cloud data; detects a line segment indicating the front surface of the pallet based on the straight line; acquires position and orientation of the pallet based on the line segment. Acquires one or more straight line candidates and assigns for each of the one or more straight line candidates a score to the point cloud and selects the straight line from the one or more straight line candidates based on a score accumulated value obtained by accumulating the score for the point cloud in the region presumed to include the front surface of the pallet.

A device is for estimating a position of a vehicle equipped with a laser scanner capable of acquiring point cloud data by scanning a laser beam and a camera capable of acquiring an image in a predetermined direction. The device includes an acquisition unit configured to acquire the point cloud data and the image, an estimation unit configured to estimate the position based on the point cloud data or the image, and an extraction unit configured to extract, from the point cloud data, valid point cloud data that is usable for estimating the position. The estimation unit is configured to estimate the position using: (i) the valid point cloud data if a number of pieces of valid point cloud data is equal to or greater than a predetermined number; and (ii) the image if the number of pieces of valid point cloud data is less than the predetermined number.

A cardboard sheet manufacturing system includes an information editing unit storing production state information, operation state information, and warping state information as acquisition information in a storage unit, the information editing unit deleting, in a case where the stored acquisition information includes prescribed information to be deleted, the information to be deleted from the storage unit and outputting the acquisition information stored in the storage unit as editing information. The system also includes an editing information storage unit storing the editing information output from the information editing unit, a prediction model calculation unit calculating a prediction model of the warping state based on the editing information stored in the editing information storage unit; and a control table update unit updating a target value of a control value of a control element in the cardboard sheet manufacturing apparatus, based on the prediction model.

The self-localization device includes: an acquisition unit configured to acquire a sight image from a camera which is mounted in a mobile object; an estimation unit configured to perform a self-localization process of estimating a position and a posture of the mobile object in a world coordinate system on the basis of positions of feature points in the sight image and a map on which positions of a plurality of feature points in the world coordinate system are recorded; and a registration unit configured to register the sight image as a key frame for adding a new feature point included in the sight image to the map. The registration unit is configured to register the sight image as the key frame when movement of the mobile object satisfies a condition which is prescribed for at least one of the position and the posture of the mobile object.
