摘要： PROBLEM TO BE SOLVED: To provide a safe drive diagnostic device capable of reducing erroneous decision that safety confirmation is performed by the safety confirmation is not performed in an intersection and reducing erroneous decision that the safety confirmation is not performed by the safety confirmation is performed.
SOLUTION: The safe drive diagnostic device performs the sampling of a horizontal angle signal for 5 [s] before a time point when an own vehicle C enters at a longer distance than 2 [m] from an entry position of the intersection (S10-S16). The safe drive diagnostic device calculates an absolute value of an average of horizontal angles before and after 5 [s] before the time point, and processes the horizontal angle signals performed with the sampling in a sampling part 13a when the absolute value is a prescribed value or larger (S17, S18). The safe drive diagnostic device calculates a power spectrum from the horizontal angle signal performed by the sampling, calculates a total of maximal values of power in 0.2-1.5 Hz, compares a decision value with the total, and decides whether or not the safety confirmation by a driver is performed (S19-21).

摘要： PROBLEM TO BE SOLVED: To early detect sleepiness and lack of vigilance by imaging a face image using a camera etc., detecting sight line from the face image, analyzing detailed motion of the sight line, and determining vigilance.
SOLUTION: In a means to detect the sight line by measuring the face image using the camera etc., a middle point of eyeballs is presumed through acquisition of feature points, basic reference points, etc. of the face from the face images, trace of feature points of the face in consideration of direction or rotation of the face, and detection of blink, etc. The sight line can be presumed by calculating the amount of displacement of iris of the eye by computing a projected point on an image surface from the middle point of presumed eyeballs. When gazing at front, usually minute motion of the sight line is active, its coverage is large and information can be acquired correctly. Meanwhile, when sleepiness arises or vigilance declines, minute motion of the sight line becomes inactive and its coverage is narrow, and information cannot be acquired correctly. Therefore, if the coverage of the minute motion of the sight line is analyzed, sleepiness and lack of vigilance can be determined and early detected.

摘要翻译：要解决的问题：通过使用照相机等对脸部图像进行成像来早期发现困倦和缺乏警觉性，从脸部图像检测视线，分析视线的详细运动并确定警戒性。
解决方案：通过使用照相机等测量脸部图像来检测视线的手段，通过从面部图像中获取脸部的特征点，基本参考点等，推测出眼球的中点考虑面部的方向或旋转的面部特征点的轨迹，以及眨眼等的检测。可以通过计算图像上的投影点来计算眼睛的虹膜的位移量来假定视线从假定的眼球的中点的表面。当前面注视时，通常视线的微小动作是活动的，其覆盖面大，信息可以正确获取。同时，当困倦出现或警惕性下降时，视线的微小动作变得无效，覆盖范围狭窄，无法正确获取信息。因此，如果分析视线的分钟运动的覆盖范围，则可以确定睡眠和缺乏警惕性并及早发现。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a shape measuring method and its system that can shorten the measuring time and eliminate the constraint by color and tilt of a measured object. SOLUTION: A position and attitude of the measured object is estimated by comparing and collating imaged data obtained by photographing the measured object with an imaging means with CAD data of the measured object, and position/attitude estimation data of the measured object is acquired. Based on the obtained position/attitude estimation data, a contact type probe is moved at a high speed between measured points in the measured object. When the contact type probe arrives at the proximity of the position at which the measured object is estimated to exist, the deceleration is started, and the contact type probe is brought into contact with the measured object at a low speed. When the contact type probe comes into contact with the measured object, the contact type probe is stopped and measurement is started. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method capable of measuring the entire mold cavity surface in a relatively short period of time. SOLUTION: A three-dimensional coordinate is composed by using an image of a mold cavity surface captured by a camera for measuring a reference position. A wire flame model of the mold cavity surface produced by CAD data is rotated and moved in parallel to be virtually disposed at the same position as the image of the mold cavity surface. One measuring point P at the bottom or side part is photographed by a camera for stereo measurement, and a pair of image patterns is extracted from a peripheral small area on the stereo image of the measuring point P. Pattern matching processing is performed by setting one of the pair of image patterns as a reference image pattern and the other one as a comparison image pattern to find out a true corresponding point. A process for restoring the three-dimensional coordinate on the real mold cavity surface corresponding the measuring point P is repeated many times, so as to measure multiple three-dimensional coordinates for the measuring point P. Based on the multiple three-dimensional coordinates for the measuring point P, the surface is restored, so as to produce the image of the mold cavity surface and evaluate it.

The small-sized pressure measuring device provided with the pressure sensors is capable of simultaneously calculating the driver's gripping force and the gripping positions. The arrangement of the pressure sensors is determined, by recording in advance gripping action at simulated running for each setting section as images and by extracting the positions of the driver's hands, and further, accurate gripping forces can be measured, by distributing and arranging the pressure sensors so as to face the direction in matching with the gripping forces applied.
