Abstract
The invention relates to a virtual test system and method based on the infrared touch screen touch point identification algorithm. According to the virtual test system and method, a touch simulation module in a testing module is used to replace a carving machine in an existing testing system, a to-be-tested algorithm executing module in the testing module is used to replace a touch screen in the existing testing system, and therefore hardware testing equipment such as the carving machine do not need to be purchased and test expenses can be saved; furthermore, due to the fact that the hardware equipment such as the carving machine and the touch screen are replaced by a computer virtual testing system, measurement errors and external disturbance caused by the hardware equipment such as the carving machine and the touch screen of the existing testing system can be effectively reduced, and the testing precision of the testing system is improved to a large extent. When the hardware equipment such as the carving machine are controlled, the movement of a control touch bar takes time, and therefore time for testing is long. After the virtual test system and method are adopted, time for testing is shortened greatly due to the fact that all the testing steps are replaced with a computer.
