The method for locating a certain object is a method for locating the object by means of a detected locating signal. With this method, locating of precisely this object is checked in such a way that an object with at least a temporally variable reflective property is used, and an influence of this reflective property on the detected locating signal is checked. The locating system has a locating sensor for locating an object by means of a locating signal detected by a locating sensor, as well as an evaluating device which is configured to check an influence of a temporally variable reflective property of the object on the locating signal detected by the locating sensor.

A method for filtering in ranging of a UAV is provided, which is based on a characteristic that velocities of the UAV change continuously during a moving process. A current velocity of the UAV is obtained via seeking difference of distances measured by the sensor, then a variance of continuous velocities is calculated and it is determined whether a current distance is valid according to the variance. The general process of the method is as follows. First, initial distances measured by the sonar sensor are acquired, secondly, it is determined whether a new distance is valid according to the initial distances, if the new distance satisfies a curtain condition, the new distance is considered to be valid and the initial distances are updated; if the new distance does not satisfy the curtain condition, a distance is estimated and used as the current distance and the initial distances are maintained.

An in-vehicle object determining apparatus cooperates with an obstacle sensor unit, which detects an obstacle at a first time. An estimated detected state is calculated as a detected state of the obstacle estimated to be detected by the obstacle sensor unit at a second time after a lapse of a predetermined time period from the first time, on condition that the obstacle is assumed to be under stationary state, based on (i) a vehicle-relative position of the obstacle detected at the first time, (ii) a sensor position of the obstacle sensor unit, and (iii) a vehicle position change during a period from the first time to the second time. It is determined that the obstacle is a moving object based on a discrepancy between the estimated detected state of the obstacle and a real detected state of the obstacle actually detected by the obstacle sensor unit at the second time.

A vehicle guidance system assists a driver in maneuvering a vehicle with respect to an object in a scene. The system includes a steering angle sensor, a camera device, a video processing module (VPM), and a human-machine interface (HMI). The sensor is configured to monitor the angular position of a vehicle wheel. The device is configured to capture an original image of a scene having the object. The VPM is configured to receive and process the original image from the device, detect the object in the original image, receive and process the angular position from the sensor, generate a vehicle trajectory based on the angular position, and orientate the trajectory with regard to the object. The HMI is configured to display a processed image associated with the original image and a trajectory overlay associated with the trajectory from the VPM. Together, the object is displayed in relation to the overlay.

In one form, an acoustic signal is generated for an acoustic transducer, where the acoustic transducer transmits the acoustic signal to determine a first position of an obstacle. In response to the acoustic signal encountering the obstacle within a predetermined distance, an echo, or pulse, is detected at the acoustic transducer. At a first time, a magnitude is detected in response to a rising edge of the pulse intersecting a determined threshold. A second magnitude is detected in response to the detection of a first peak of the pulse. A time of flight of the acoustic signal, within the predetermined distance, is determined when a compensation time is extracted from a correction calculation algorithm in response to detecting the first magnitude and the second magnitude. The compensation time is subtracted from the first time, and the difference of the compensation time and the first time is the time of flight.
