Abstract: A method of length measurement for 2d photography comprises the following steps. A reference object and a measuring object are respectively photographed to form a reference image and a measuring image, wherein the reference object has a geometrical shape capable of being represented by an area formula saved in a computer with a predetermined size. A background image is separated from the reference image and then the reference image is scanned to obtain a total number of pixels included therein, and a first number of pixels corresponding to a unit length is obtained based on the predetermined size and the area formula. An actual length between any two points of the measuring object image clicked on a screen of the computer can be obtained based on a ratio of a second number of pixels corresponding to the two points to the first number of pixels.

Abstract: A turntable with a light transmission round platter and at least one light collection spindle is provided. The light transmission round platter connects to the light collection spindle, and the light collection spindle is driven by a motor to rotate the light transmission round platter. A portion of surface of the light collection spindle is frosted. The incident light from a bottom or a lateral side is collected in a light collection area of the spindle and then transmitted toward a conjunctive area of the light transmission round platter via a transparent and smooth light guiding area, so as to lighten the originally dark conjunctive area and reduce the darkness thereof. Accordingly, the time spent in background removal of the dark conjunctive area can be reduced since the conjunctive area is lighted when the light transmission round platter is rotated for photographing an object to be photographed thereon.

Abstract: A device for extending and controlling signals of a camera shutter release cable through an isolated switch is provided. A single short signal is generated to a camera shutter release cable by a manual button, another control device or a computer command, and extended into a multiple short signal with well isolation, good stability and enough voltage level through multiple isolated switches, so as to simultaneously activate several cameras connected in parallel to focus and snap. Therefore, it is able to prevent that the voltage levels provided by a single short signal are too low to simultaneously activate all of those cameras connected from the interference between them. Moreover, the foregoing multiple short signal can further be individually, partially or together controlled by a computer, a USB and a CPU, so as to simultaneously activate the cameras connected in parallel to focus and snap rapidly.
