A vehicle safety system includes several image capturing units, an image processing unit, a control unit and a display unit, in which an environmental photography technique and a visual distance detection technique are integrated so as to detect a distance between a nearby object and the vehicle to warn the driver during moving or parking operation, and an automatic door detection technique is integrated to identify rear side objects prior to opening of a vehicle door so to prevent undesired accident from happening.

When there are no customers in a store, a laser is scanned along an aisle between product shelving units installed in the store, and if that laser is reflected midway in the optical path, it is determined that there is an object in the sensing range according to the laser. The determination result is then notified to a user by a site that corresponds to the position where the laser has been reflected being marked in a layout image that represents the product shelving units, displayed on a terminal device.

The present invention relates to a LASER RANGE FINDER, and more particularly, to a LASER RANGE FINDER which includes a first laser transmitting unit and a second laser transmitting unit transmitting a laser in different directions and controls angles of a first module and a second module including the first laser transmitting unit and the second laser transmitting unit, respectively to effectively measure a distance between a first specific object and a second specific object and further, easily measure the length of a specific object.

A light beam scanning device includes a lens element assembly which dynamically adjusts a divergence of the beam. The lens element assembly can include multiple lens elements, one or more of which translates parallel to the light beam to adjust beam divergence. Divergence adjustment can include adjusting the beam divergence along one or more cross sectional axes of the beam. Beam divergence can be adjusted between consecutive scans, during a scan, etc. Beam divergence can be adjusted based on the field of view and scan rate. Beam divergence adjustment can enable dynamic adjustment of the spot size of the beam, which can enable the apparatus to adjust between scanning a wide divergence beam to detect objects in a scene and scanning a narrow divergence beam to generate detailed point clouds of the detected objects. Beam divergence adjustment can enable adjustment of reflection point intensity, enabling detection of low-reflectivity objects.
