    摘要: A steering angle control apparatus for controlling steering angles of front wheels and rear wheels of a vehicle includes a yaw rate detector for detecting an actual yaw rate of the vehicle. A desired yaw rate calculator estimates a desired yaw rate for causing the vehicle to drive stably. A yaw rate disturbance calculator calculates a yaw rate disturbance which causes the detected yaw rate to deviate from an ideal yaw rate of the vehicle assuming driving in ideal driving conditions. A desired yaw rate compensator compensates the desired yaw rate based on the calculated yaw rate disturbance and produces a compensated yaw rate so that the desired yaw rate tracks the compensated yaw rate.

    摘要: To classify moving images using audio signals. An audio signal is acquired, a section feature relating to an audio frequency distribution is extracted with respect to each of a plurality of sections each having a predetermined length contained in the acquired audio signal, each extracted section feature is compared with each of reference section features to calculate a section similarity indicating a degree of correlation between each section feature and each reference section feature. An integrated feature relating to the plurality of sections and being calculated based on the section similarity calculated with respect to each of the plurality of sections is extracted from the acquired audio signal. The extracted integrated feature is compared with each of one or more reference integrated features, and the audio signal is classified based on comparison result. Then, classification result is used for moving image classification.

    摘要: Provided is a repeater for relaying communication by achieving synchronization with a base station and a mobile station without using GPS. The repeater includes a donor unit communicating with the base station and a remote unit communicating with the mobile station. Upon receipt of a signal from the base station, the donor unit specifies a preamble of the received signal to achieve synchronization with the base station. This determines start of each frame in the communication between the base station and the repeater. After the synchronization achievement, the remote unit starts performing procedures for achieving synchronization with the mobile station. Upon notification of the start timing of each frame from the donor unit, the remote unit determines the notified timing as start timing of each frame in the communication between the repeater and the mobile station, and transmits a preamble referred to by the mobile station when it achieves synchronization.

    摘要: This invention aims to ensure accuracy of a three-dimensional model to be registered. With information a of three-dimensional information a, b, c restored by measuring an actual model of a work, which is a target of three-dimensional recognition, from different directions as a reference, other three-dimensional information b, c are coordinate transformed so as to be aligned with the reference three-dimensional information, and three-dimensional information d including all of three-dimensional information b′, c′ after the transformation and the reference three-dimensional information a is created. The three-dimensional information d is temporarily registered as the three-dimensional model. A difference amount among the integrated three-dimensional information a, b′, c′ is calculated, and an evaluation index based on the difference value is displayed with an image view of a contour pattern represented by the three-dimensional model. A user checks the accuracy of the three-dimensional model on this display screen from a degree of variation of the contour line representing the same site and a value of the evaluation index, and determines whether or not to actually register the three-dimensional model d.

    摘要: In a rendering device Urnd1, a CPU 7 receives a captured image each from two image capture devices 1 and 2. The CPU 7 then receives a steering angle of a steering wheel of a vehicle from a steering angle sensor 3. Based on the steering angle, the CPU 7 derives an estimated trajectory for the vehicle to take in the course of time. Then, with reference to the estimated trajectory, the CPU 7 selects several pixels each from the captured images, and then generates a drive assistant image based on those pixels. In this manner, the drive assistant image generated by the rendering device Urnd1 hardly causes the driver to feel strange.
