A system includes a processor and a display. A LiDAR is attached to a work machine and includes a laser and a photodetector. The LiDAR measures a distance to at least a part of a work implement and a distance to an object around the work machine. The processor acquires position data from the distances measured by the LiDAR. The position data indicates a position of at least the part of the work implement and a position of the object around the work machine. The processor generates an image indicative of the position of at least the part of the work implement and the object around the work machine based on the position data. The display displays an image in response to a signal from the processor. The system may further include the work machine and the LiDAR.

Systems and methods may detect an object within a minimum predetermined distance of a LIDAR system. The LIDAR system may comprise a processor configured to control a light source and a light deflector to illuminate objects located in a space illuminated by the light source; determine a distance to a first object based located within a field of view of a LIDAR sensor; receive, from a supplementary sensor, reflection signals indicative of light reflected from a second object outside the field of view; determine, based on the second reflection signals that the second object is located within a predetermined distance; and regulate, based on the determination, at least one of the light source and the light deflector to prevent an accumulated energy density of light emitted by the light source from exceeding a maximum permissible exposure level.

An object amount calculation apparatus includes: a receiver configured to obtain a first three-dimensional model and a second three-dimensional model different from the first three-dimensional model, each of the first three-dimensional model and the second three-dimensional model representing a same space, each of the first three-dimensional model and the second three-dimensional model being constituted with regions having respective attributes; and a processor configured to: align the first three-dimensional model and the second three-dimensional model based on at least one attribute of the first three-dimensional model and the second three-dimensional model; calculate, for each of the attributes, a difference between the first three-dimensional model aligned and the second three-dimensional model aligned; and output (i) a total amount of differences corresponding to two or more attributes among the attributes and (ii) information on the two or more attributes.

A scanning surveying system comprises a base 5, an alidade 3 mounted on the base, a first motor 6 to rotate the alidade about a first axis 9, a rotating mirror 21 rotatable about a second axis 16, a second motor 23 to rotate the mirror. An optical distance measuring unit 11 is configured to direct measuring light onto the rotating mirror such that it is reflected towards objects and to receive measuring light back from these objects via the rotating mirror. The system further comprises a camera 81 and a controller for controlling the first motor based on the images recorded by the camera such that the measuring light is reflected from the rotating mirror in a direction corresponding to a selected location within the image.
