Abstract: The present invention discloses a composite-image parking-assistant system, which is installed in a vehicle. When a driver drives his vehicle to passes at least one parking space, the system of the present invention uses camera devices to capture images involving the parking space. A processing unit converts the images into bird's eye view images and integrates the bird's eye view images into a composite bird's eye view surrounding map via the common characteristics thereof. A display device presents the surrounding map to the driver. The processing unit adjusts the coverage the vision field of the surrounding map according the relative position of the vehicle and the parking space to make the magnification of the vision field inverse proportional to the relative position. Thereby, the driver can park his vehicle efficiently and avoid collision.

Abstract: The present invention discloses a parking pilot system and method. The system of the present invention comprises a display, at least one image sensor, at least one speed sensor and an ECU. The ECU uses the images captured by the image sensor to calculate an intended parking position and uses the captured images and the detected speed to work out the coordinates of the current position and the intended parking position. The ECU also works out an initial parking position. According to the adopted parking mode, the ECU presents on the display a forward pilot track extending from the current position through the initial parking position to the intended parking position, or a forward pilot track extending from the current position to the initial parking position. Then, the driver can easily park his vehicle and effectively avoid collision via the pilot instructions presented on the display.

Abstract: The present invention discloses a fast object position detection device and a method thereof, particularly to a detection device and a method thereof which can directly apply to various image systems. The device of the present invention mainly comprises an image capturing system that captures images within the regions defined by the user, and an image processing unit determining the position of an object and obtaining related information. In the method of the present invention, a captured image is converted into 1-D distance-axis signal information; a differential value of the 1-D distance-axis signal information is used to determine a position of an object; and a difference of the 1-D distance-axis signal information of at least two adjacent time points is used to determine an approaching status of an object.

Abstract: Disclosed is a hand-held input device having a rotating mechanism. The hand-held input device includes a shell body and a rotating component. An outer surface of the shell body forms a storage cavity in which a spindle hole and a guide groove are formed. The rotating component is assembled with a spindle and a guider that the spindle and the guider match with the spindle hole and the guide groove of the shell body respectively. The spindle is fixed a pressing ring with an elastic part therebetween. A cover is capped on the storage. The elastic part keeps a space between the shell body and the rotating component. A rotation limitation mechanism limits the rotation of the rotating component within a specified rotating angle range with respect to the shell body by the limitation of the guide groove to the guider.
