Methods and systems for detecting environmental information of a vehicle

Номер: AU2017417170A1
Принадлежит: Shelston IP Pty Ltd.

A system for detecting a surrounding object may receive, from a camera, a first image including a plurality of pixels relating to one or more objects and receive, from one or more LiDARs, a first point set including a plurality of points corresponding to the plurality of pixels. The system may also, based on the first point set, determine 3D coordinates and reflection intensities of the plurality of points, based on which the system may generate a segment result by classifying the plurality of points. The system may further transform the 3D coordinates of the plurality of points into 2D coordinates and determine an object type of the one or more objects based on the 2D coordinates, the 3D coordinates, the segment result, and the first image.

Point-cloud-image generation device and display system

Номер: AU2015395741B2
Принадлежит: Griffith Hack

The directions and distances to a plurality of irradiation points are measured through the irradiation of surrounding objects by a laser from a laser scanner (115) attached to a measurement vehicle (110). On the basis of the measured values at each irradiation point, a three-dimensional point cloud generation unit (123) generates three-dimensional point cloud data (203) that is data indicating the three-dimensional coordinate values of each irradiation point. A two-dimensional projection unit (230) carries out two-dimensional projection processing on the three-dimensional point cloud data on the basis of a viewpoint position and line-of-sight direction and generates a point cloud image. An operation unit (400) corresponds to a user interface for independently changing the viewpoint position and line-of-sight direction.

A three dimensional scanning beam and imaging system (800) enable economical and efficient three dimensional scans of an environment. The system (800) includes a ranging apparatus (805), and a reactive linkage mechanism (810) having a first end (815) and a second end (820). The first end (815) is connected to the ranging apparatus (805) and the second end (820) is connected to an object (825) that moves the system (800) through an environment. Additionally, an imaging apparatus (840) is operatively coupled to either the first end (815) or the second end (820) of the reactive linkage mechanism (810). In use acceleration of the object (825) with respect to the environment is converted by the reactive linkage mechanism (810) to motion of the ranging apparatus (805) with respect to the object (825), which increases the field of view of the ranging apparatus (805) with respect to the environment.

As commercialization of a drone which is an unmanned aerial vehicle is imminent, a technical demand for self-position recognition of the drone is greatly increasing. A position is recognized by using GPS in a general external environment. Recognition accuracy is as high as several meters. Because hiding is generated by a building, the GPS is not used in a building environment. To solve problems, a local positioning system which is LPS is necessary. A conventional LPS installs three or more signal generating devices corresponding to a satellite of the GPS at a specific fixing position; and recognizes the position by analyzing signals received in the signal generating devices. The conventional LPS cannot be used in an area in which the signal generating devices are not installed. The present invention recognizes a self-position and a gesture by measuring three positions in which a sensor module in which a distance detecting sensor and a camera are combined is fixed without using an external ...

The IR system obtains IR image data in the IR FOV. The ladar system initially transmits with a smaller laser FOV to illuminate possible targets, rapidly interrogating the IR FOV. The ladar system obtains data on each possible target to perform primary discrimination assessments. Data fusion is employed to resolve the possible targets as between decoys/clutter and a reentry vehicle. The laser FOV is expandable to the IR FOV. Robust and reliable discrimination is obtained at high altitudes.

The present invention is in general related to automatic alignment in multi-sensor target tracking. The process of the invention repeatedly generates estimates for sensor bias errors (b) by minimising a function, given on one hand by the magnitude of the discrepancy between measurements (M) and a measuring model, where the measuring model is a function of the unknown target location and unknown bias parameters, and on the other by the bias parameters and their predetermined statistical distributions (15). In a preferred embodiment of the present invention, the minimising step is performed by linearising components of the function around an approximate target position (normally obtained from the tracker (10)) and around nominal (typically zero) bias errors, and the function is subsequently minimised with respect to target positions as well as to the bias parameters (b). In addition, possible time dependence of the bias parameters are modelled by the incorporation of process noise.

System and Method for Increasing Resolution of Images Obtained from a Three-Dimensional Measurement System

Номер: US20190033456A1

A system uses range and Doppler velocity measurements from a lidar system and images from a video system to estimate a six degree-of-freedom trajectory (6DOF) of a target. The 6DOF transformation parameters are used to transform multiple images to the frame time of a selected image, thus obtaining multiple images at the same frame time. These multiple images may be used to increase a resolution of the image at each frame time, obtaining the collection of the superresolution images.
