Abstract: The present disclosure discloses a laser detection method for port machinery equipment including: providing with a laser radar device: selecting a suitable laser radar device and installing on the port machinery, ensuring that an installation position and angle of the device can provide a good detection range and field of view; emitting and receiving laser: emitting a laser beam and receiving reflected light signals by the laser radar device, emitting a pulsed laser beam by the laser radar device, forming a narrow beam of laser by focusing with an optical component. The laser detection method uses a Velodyne® VLP-32C infrared laser, which has high resolution and a large number of detection points, can provide high-precision laser data to more accurately describe a port environment and target objects. Through a PointNet++deep learning mode, global perception and analysis of laser data can be carried out to obtain target object information.

Abstract: The present disclosure relates to a traceable in-situ micro- and nano-indentation testing instrument and method under variable temperature conditions. A macro-micro switchable mechanical loading module, a nano mechanical loading module and an indentation position optical positioning module are fixed on a gantry beam, an optical imaging axis of an optical microscopic in-situ observation or alignment module and a loading axis of the nano mechanical loading module are coplanar, the optical microscopic in-situ observation or alignment module and the function switchable module are mounted on a table top of a marble pedestal, and a contact or ambient mixed variable temperature module is fixedly mounted on the function switchable module. A modular design is adopted, the micro- and nano-indentation testing instrument is used as a core, in combination with a multi-stage vacuum or ambient chamber, an indentation depth traceability calibration module and multiple sets of optical microscopic imaging assemblies.
