摘要： PURPOSE:To accurately and quickly calculate the three-dimensional position of an object, even when the characteristic point thereof is unavailable, by providing a calculation means or the like for computing the unknown of the dislocation and displacement angle of the object relative to a reference position. CONSTITUTION:The reference coordinate data of an attention point on an object assumed to be at the preset reference position is extracted with the first extraction means 7. Also, the detected coordinate data of an actual object attention point detected with an object detection means 3 is extracted with the second data extraction means 8. Then, a sight line vector is established to give an equation for finding the amount of the dislocation or the like of the object relative to the reference position, on the basis of the detected coordinate data and the reference coordinate data. Then, the equation obtained depending on the sight line vector is solved, and the unknown of a positional conversion factor regarding one of the reference coordinate data of the attention point and the detected coordinate data is calculated, thereby finding the amount of the dislocation of the object as well as the displacement angle thereof relative to the reference position.

摘要： PROBLEM TO BE SOLVED: To accomplish a steering reaction force control mechanism capable of suitably setting a steering reaction force according to a driver, and to contribute to the reduction of a burden of steering or accurate steering angle control. SOLUTION: A control unit 11 detects an operation amount of steering operation of a drive applied to a steering wheel performed at predetermined timing and presumes a mechanical impedance of the driver based on the detected operation amount. Thereafter, the steering reaction force of the steering wheel is controlled based on the presumed mechanical impedance. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To obtain a method in which the camera calibration of slit light and the acquisition of shape data on a product to be measured can be performed collectively and automatically with reference to the coordinate system of a robot. SOLUTION: The calibration of a position detector 1 and the measurement of a product shape are performed by using the position detector 1 which is composed of a slit light source 2 used to shine slit light I at a product W to be measured and of a camera 3 used to photograph the image of the slit light I. At this time, a camera parameter in a perspective conversion system which converts the coordinate system of the product W to be measured into a coordinate system on the image by the camera 3, a slit-light parameter in the plane system of the slit light I shone at the product W to be measured and a model parameter in a shape expression system which expresses the shape of the product W to be measured are decided by moving the position detector 1 in the prescribed number of times. Thereby, the camera calibration of the slit light and the acquisition of shape data on the product W to be measured can be ]collectively and automatically with reference to the coordinate system of a robot.

摘要： PROBLEM TO BE SOLVED: To miniaturize the whole device and reduce cost in a steering angel ratio varying unit having an input shaft connected to a steering and an output shaft connected to a wheel. SOLUTION: This steering device includes: a moving member 20 on an input side, connected to the input shaft 3 through a ball screw portion 3a and linearly moved by rotation of the input shaft 3; a moving member 21 on an output side, connected to the output shaft 4 through a ball screw portion 4a and rotating the output shaft 4 by linear movement; and a link mechanism 30 transmitting the linear movement from the moving member 20 on the input side to the moving member 21 on the output side. The link mechanism 30 transmits the linear movement so that the linear movement of the moving member 20 on the input side and the linear movement of the moving member 21 on the output side become nonlinear.
