A point cloud display method includes determining, from a first point cloud, points describing a target object, where the first point cloud describes a surrounding area of a vehicle in which the in-vehicle system is located, and the target object is to be identified by the in-vehicle system, generating a second point cloud based on the points, and displaying the second point cloud.

A non-contact gesture control module based on the principle of infrared reflection, contains a sensing area composed of a plurality of infrared transmitting tubes and a plurality of infrared receiving tubes, the infrared transmitting tubes and the infrared receiving tubes being alternately arranged in an extending direction. A control circuit controls the switching on and off of the individual infrared transmitting tubes and the individual infrared receiving tubes. A signal processor is provided for receiving and processing signals generated by the plurality of infrared receiving tubes and determining a coordinate position of an object in the extending direction above the sensing area. The gesture control module performs precise non-contact control and fine adjustment of gears and thus stepless speed regulation of a household appliance.

A measuring tool (10) comprises a laser level (11) and a distance meter (12); the measuring tool (10) comprises a limit means located on one of the laser level (11) and the distance meter (12), and employed for the superposition of the laser level (11) and the distance meter (12); when located on the laser level (11), the limit means comprises protruding strips (13) on the two lateral edges of the laser level (11), wherein the distance between the protruding strips (13) is equivalent to the width in the radial direction of the distance meter(12), such that the distance meter(12) is caught between the protruding strips. A compact and portable measuring tool (10), comprises a small-scaled laser level (11) and a small-scaled distance meter (12), which can not only be employed individually for implementing their respective function, but also combined and matched with each other to project lines and measure distance at the same time, thereby achieving unexpected beneficial effects.

An HMD adjusts adjusting depth information based on detected motion of the system. The HMD includes a depth camera that collects depth data for objects in the local environment of the HMD. The HMD further includes an inertial measurement unit (IMU) including non-visual motion sensors such as one or more accelerometers, gyroscopes, and the like. The HMD adjusts the received depth information based on motion data provided by the IMU, thereby improving the accuracy of the depth information, and in turn reducing visual artifacts that can result from inaccuracies in the depth information.

A LIDAR system for vehicle operation that can operate in degraded visual environments (DVE) is described. The LIDAR system may use a spatial light modulator to find the phase conjugate of the DVE being traversed by the laser beam and cancel out the backscatter from the DVE, which allows the detection of extremely small numbers of directly reflected photons reflected by a target surface. If the target is not detected, the LIDAR is iteratively scanned to its maximum available depth of focus until the target is acquired. The LIDAR system is especially useful for autonomous landing of VTOL aerial vehicles in locations where the target landing spot is approximately known but cannot be directly visualized due to DVE media, such as smoke, dust, fog, or the like.

An acquisition unit acquires laser measurement data every time a laser measurement is performed. Based on the acquired laser measurement data, a first detection unit detects an attention angle, which is an irradiation angle corresponding to a measurement distance not included in a standard distance range. A second detection unit detects a warning angle, which is an irradiation angle matching the attention angle for a time longer than an allowable time. A warning unit issues a warning when the warning angle is detected.
