Abstract: The invention relates to a time-of-flight selective flash LiDAR system comprising an emitter for emitting pulsed illumination radiation into an object space; a detection unit with an image sensor for detecting the radiation reflected back from the object space; and a sensor control device for time-of-flight selection, wherein the sensor control device is configured such that the back-reflected radiation is detected separately from a first measuring surface and a second measuring surface and wherein the second measuring surface is located at a greater distance from the detection unit than the first measuring surface. The invention is characterized in that there is an illumination field control arrangement which is synchronized in time with the sensor control device and is configured in such a way that the illumination radiation generates a first illumination field with a first solid angle extension on the first measuring surface and a second illumination field with a second solid angle extension on the second measuring surface, and the first solid angle extension is greater than the second solid angle extension.

Abstract: An array-based light detection and ranging (LiDAR) unit includes an array of emitter/detector sets configured to cover a field of view for the unit. Each emitter/detector set emits and receives light energy on a specific coincident axis unique for that emitter/detector set. A control system coupled to the array of emitter/detector sets controls initiation of light energy from each emitter and processes time of flight information for light energy received on the coincident axis by the corresponding detector for the emitter/detector set. The time of flight information provides imaging information corresponding to the field of view. Interference among light energy is reduced with respect to detectors in the LiDAR unit not corresponding to the specific coincident axis, and with respect to other LiDAR units and ambient sources of light energy. In one embodiment, multiple array-based LiDAR units are used as part of a control system for an autonomous vehicle.

Abstract: Techniques are disclosed to enable an electronic system for use in connection with navigating a marine vessel to a desired position with respect to a waterline boundary. The system has one or potentially more light detection ranging (LIDAR) sensors for detecting structures across a region by vertically scanning the region using the LIDAR sensors. The system also includes a memory element configured to store characteristics of the detected structure. Additionally, the system includes a processing element that can identify a primary reference point associated with navigation of the marine vessel to the desired position based on the characteristics of the detected structure and display information about a current position of the marine vessel in relation to the desired position.

Abstract: The present invention relates to a driving device, a driving method, and a light-emitting unit that make it possible to appropriately drive a light-emitting element.
The driving device according to the present invention includes: a setting section (161) that sets at least one of a bias current of a light-emitting element (an LD 121) or a target current for setting output light from the light-emitting element (the LD 121) to desired intensity on the basis of a result of detection of an offset light amount when the light-emitting element (the LD 121) does not emit light; and an output controller (164) that controls an output of a driving current of the light-emitting element (the LD 121) on the basis of at least one of the set bias current or the set target current. The detection of the offset light amount is performed by a light-receiving element (a PD 122) that receives a portion of the output light.
The present invention is applicable to a ranging module, for example.

Abstract: Disclosed herein are examples of ladar systems and methods where data about a plurality of ladar returns from prior ladar pulse shots gets stored in a spatial index that associates ladar return data with corresponding locations in a coordinate space to which the ladar return data pertain. This spatial index can then be accessed by a processor to retrieve ladar return data for locations in the coordinate space that are near a range point to be targeted by the ladar system with a new ladar pulse shot. This nearby prior ladar return data can then be analyzed by the ladar system to help define a parameter value for use by the ladar system with respect to the new ladar pulse shot. Examples of such adaptively controlled parameter values can include shot energy, receiver parameters, shot selection, camera settings, and others.

Abstract: A measurement device includes a processor coupled to a memory storing instructions. The processor is configured to acquire positional information of a measurement object stored in a storage unit, acquire point group information of points indicating a surrounding feature acquired by an external sensor, output reliability of the positional information of the measurement object indicating a center position of the measurement object existing in a predetermined range based on the point group information of points existing in the predetermined range, the predetermined range being determined based on a position of a movable body, and estimate a movable body position based on the positional information of the measurement object and the center position of the measurement object, wherein the processor determines the center position by calculating an average value of the point group information existing in the predetermined range.

Abstract: A vehicle, detection system and method for detecting a location of an object with respect to a vehicle is disclosed. The method includes transmitting, at the vehicle, a structured light pattern at a selected frequency into a volume that includes the object and receiving, at a detector of the vehicle, a reflection of the light pattern from the volume. A processor determines a deviation in the reflection of the structured light pattern due to the object in the volume and determines a location of the object in the volume from the deviation.
