Abstract
The invention, which belongs to the photoelectric measuring technology field, relates to an optical target system based on LED display. The system comprises: a display target, a control apparatus and a computer. The computer makes a target display content and transmits to the control apparatus. The control apparatus makes and drives the display target to display the target display content. The display target is formed by assembling display element modules and is installed and fixed by a target plate framework, wherein the display element modules are formed by LED display device arrays and the LED display devices have a same structure. In the invention, the LED display devices substitute target sheets or target clothes of traditional targets so that a dynamic display content can be changed at any time without changing the target sheets. The target has high brightness. Monochrome or color display can be performed according to needs. Display precision can be controlled. Demands of an apparatus precision test and an object identification tracking test can be satisfied. The system can replace the traditional target and can be used in a target range test and an optical measurement.
