A hand-held laser three-dimensional scanner performing projection using a blinking method, comprising: two or more cameras for image acquisition, two or more laser projectors for performing laser pattern projection and a controller for controlling operations of the cameras and the laser projectors. The controller comprises a camera control module for controlling the operations of the cameras according to an exposure trigger cycle. The controller also comprises an alternative blinking projection control module for starting, during two consecutive exposure cycles of the cameras, with respect to one laser projector started during a previous exposure cycle, another laser projector the next time. The alternative blinking projection control module is connected to a switching circuit. The switching circuit is connected to the laser projectors. The hand-held laser three-dimensional scanner performs projection using a blinking method, thereby effectively reducing the error probability and improving the scanning efficiency. |
