摘要： Optical touch display system includes a light source, a reflector, an image sensor, and a processing device. The light source emits light to at least one object directly and emits light to the at least one object via the reflector at the same time. Then the image sensor receives light reflected from the at least one object directly and light reflected via the reflector simultaneously to form a set of imaging objects which have similar color parameters on an image. Then the processing device produces a set of still image parameters of the image objects such as gravity centers and border boundaries. Based on the still image parameters, the processing device determines the coordinates of the least one object on the optical touch display.

摘要： When an object touches a touch panel, a projection light source projects a predetermined image including image information and forms an object image having the image information on a surface of the object. An image sensor captures a reflection image including the object image. Then, an angle is calculated according to an image location of the object in the reflection image and a relative position of predetermined axis, and a distance between the object and the image sensor is calculated by comparing the predetermined image with the location, size and/or phase of the image information of the reflection image so as to determine a coordinate of the object on the touch panel according to the angle and the distance.
