Shooting training and game system with virtual target

A shooting training and game system with virtual targets is revealed. The system includes a main controller, a projection module, a lens module, and a shooting tool. The shooting tool can be a real gun or a laser gun. By hardware and software of the main controller, the projection module projects a light beam to a screen therefront to form a target image area with at least one static or dynamic virtual target. Then the lens module is aligned to the target image area for detecting and obtaining relative positions and coordinates of each shot formed on the target image area by the shooting tool. Thereby an error of each shot is calculated for evaluation of shooting accuracy. The shooting training and game system is more interesting, optional and used more efficiently.

Path detection system and path detection method generating laser pattern by diffractive optical element

A path detection system and a path detection method generating laser patterns by a diffractive optical element (DOE) are revealed. The path detection system is arranged at a mobile device while in use. A laser source projects structured light toward a forward path of the mobile device through the DOE. The structure light includes a transverse baseline and at least one transverse computational line. Then a lens is used to capture images of the structured light. When there is obstacle in a forward path of the mobile device, an image processing unit makes comparisons and performs computation according to changes in position and distance of the image of the respective transverse computational line relative to the X axis and the Y axis of the transverse baseline. Thus the relative position and distance of the obstacle in the forward path is checked in a real time manner.
