A frameless touchscreen display system comprises a frameless display screen; a display system arranged to render a moving image within a display area of the frameless display screen; an image rendering component configured to receive a detected touch input, determine an action associated with a location of the detected touch input within the display area, and modify the moving image to effect the associated touch action; a 2D lidar sensor positioned so that a detection plane of the 2D lidar sensor lies adjacent and substantially parallel to the frameless display screen; and a touch input detector coupled to the 2D lidar sensor and configured to: detect the touch input based on one or more object lidar returns from an object intersecting the detection plane at said location within the display area, and estimate said location within the display area based on (i) a return time and return angle of each object lidar return and (ii) a known position of the 2D lidar sensor relative to the frameless display screen.

The present invention relates to a multi-channel lidar sensor module capable of measuring at least two target objects using one image sensor. The multi-channel lidar sensor module according to an embodiment of the present invention includes at least one pair of light emitting units configured to emit laser beams and a light receiving unit formed between the at least one pair of emitting units and configured to receive at least one pair of reflected laser beams which are emitted from the at least one pair of light emitting units and reflected by target objects.

Examples described herein provide a method that includes receiving point cloud data from a three-dimensional (3D) coordinate measurement device, the point cloud data corresponding at least in part to the object. The method further includes analyzing, by a processing system, the point cloud data by comparing a point of the point cloud data to a corresponding reference point from reference data to determine a distance between the point and the corresponding reference point, wherein the point and the corresponding reference point are associated with the object. The method further includes determining, by the processing system, whether a change to a location of the object occurred by comparing the distance to a distance threshold. The method further includes, responsive to determining that the change to the location of the object occurred, displaying a change indicium on a display of the processing system.
