There is provided a road configuration estimation apparatus that precludes influences of erroneous detection of an object and erroneous still determination and estimates a road configuration. A radar (peripheral object observation device) 110 repeatedly observes a relative position of an object relative to the moving object, which is located in the vicinity of a moving object. A stationary object identification unit (stationary object determination unit) 130 determines whether or not the object the relative positions of which have been observed by the radar 110 is still. A road approximate curve temporary computation unit (object correlation unit) 140 determines a plurality of the relative positions of an identical object observed by the radar 110 from among the relative positions observed by the radar 110. A road approximate curve main computation unit (approximate curve computation unit) 160 computes an approximate curve that approximates the configuration of a road on which the moving object is located, based on a result of the determination by the stationary object identification unit 130 and a result of the determination by the road approximate curve computation unit 140.
摘要:
Non-contact type wave signal observation apparatus takes measurements of electromagnetic waves received on an observation plane and performs hologram reconstruction calculations to reconstruct characteristics of the corresponding electromagnetic wave information at points in the observed space. The invention provides apparatus for measuring transfer functions (and, if desired, waveforms) at any point on a network containing a transmission line having distributed properties and having internal signal sources - the processing takes into account fluctuations occurring in the electromagnetic radiation given off by the network. A display for displaying complex three-dimensional data such as interference data of electromagnetic waves may be used to display data produced by the apparatus according to the invention. The complex data is converted from orthogonal co-ordinates to polar co-ordinates, the phase information is converted to hue information in a hue converter and the amplitude information is used to modulate the brightness of the displayed signal; corresponding colour signals are displayed on a colour display unit.

The disclosure relates to the field of autonomous driving technologies, and specifically provides a Lidar odometry implementation method, a computer device, a storage medium, and a vehicle, which are intended to improve the real-time performance and precision of mapping and localization. For this purpose, the method provided in the disclosure includes: obtaining a motion states prediction of a vehicle in a current cycle based on measurement data of an IMU on the vehicle in a previous cycle; obtaining a first motion states observation of the vehicle in the current cycle based on a point cloud data frame of a Lidar on the vehicle in the current cycle; obtaining a second motion states observation of the vehicle in the current cycle based on measurement data of a wheel odometer on the vehicle in the current cycle; and updating the motion states prediction based on the first motion states observation and the second motion states observation, to determine an optimal motion state of the vehicle. With the above method, the optimal motion state of the vehicle can be obtained quickly and accurately, such that the real-time performance, precision and robustness of mapping and localization can be significantly improved.
