    摘要： A technique for solving problems in laser scanning related to intense light that is reflected back from a reflector target is provided. A laser scanning control device for controlling laser scanning performed by a laser scanning apparatus includes a controller, a distance acquisition unit, and a light controller. The controller executes first laser scanning and second laser scanning. The first laser scanning is performed under conditions in which a detector of the laser scanning apparatus is saturated by light reflected back from each of reflection prisms. The second laser scanning is performed under conditions in which saturation of the detector of the laser scanning apparatus does not occur. The distance acquisition unit acquires distances to the reflection prisms based on the first laser scanning. The light controller adjusts intensity of light to be detected in the second laser scanning, based on the distances to the reflection prisms.

    摘要： Disclosed in the present invention is a head-mounted electronic vision aid device and an image magnification method thereof. The head-mounted electronic vision aid device comprising a memory unit, a processing unit, an image zooming unit, and at least one ranging unit; the ranging unit being configured to obtain distance data between a target object of interest to a user and the device and/or three-dimensional profile data of the object and output the data to the processing unit; the memory unit stores a correspondence table between the distance data and the magnification of the image zooming unit; the processing unit confirms the target object of interest to the user, performs operations on the distance data and/or the three-dimensional profile data of the object, and outputs an magnification matching the distance data to the image zooming unit according to the correspondence table; and the image zooming unit can automatically adjust to the matching magnification. For visually impaired users, accurate, intuitive and rapid automatic magnification of the target objects of interest can be realized on demand. Compared with the prior art, the repeated and tedious manual adjustment is avoided, and the user experience is greatly improved.
