An overhead bridge crane detection system comprising a lidar sensor in communication with a controller, wherein the lidar sensor and the controller are located in a housing and the housing has a means for removable attachment to an overhead bridge crane or to maintenance equipment.

A position recognizing device according to one embodiments of the present disclosure includes a ranging point acquiring section, a region determining section, and a ranging point excluding section. The ranging point acquiring section is configured to acquire ranging point information in which distances to ranging points are associated with each of electromagnetic wave applying directions. The region determining section is configured to determine whether an object region that represents a region encompassed by joining ranging points that are in close proximity to one another exists at a position closer than a specific ranging point representing a certain ranging point among the ranging points. The ranging point excluding section is configured to define the ranging point in front of which the object region exists as a false image point at which no object actually exists and exclude the false image point from the ranging point information.

A LIDAR system includes a LIDAR chip configured to output a LIDAR output signal. The LIDAR chip includes a redirection component and alternate waveguides. The redirection component receives an outgoing LIDAR signal from any one of multiple alternate waveguides. The LIDAR output signal includes light from the outgoing LIDAR signal. A direction that the LIDAR output signal travels away from the LIDAR chip is a function of the alternate waveguide from which the redirection component receives the outgoing LIDAR signal.
