System and method for calibrating display system

A method of calibrating a display system, the method comprising: displaying a test pattern comprising a plurality of spots; detecting one or more base spots in the displayed test pattern; identifying patches of the test pattern based on the detected base spots, where each patch includes one of the base spots and a subset of additional spots detected in the displayed test pattern; determining a plaque position of the at least one plaque within the test pattern based on a subset of additional spots in the plaque to determine a spot position for the at least one detected spot; determining a calibration parameter for the display system based on the spot position and a detection attribute of the at least one detected spot; and calibrating the projector using the calibration parameter. 一种对显示系统进行校准的方法，该方法包括：对包括多个斑点的测试图案进行显示；对所显示的测试图案中的一个或更多个基础斑点进行检测；基于所检测到的基础斑点来识别测试图案的斑块，其中，每个斑块包括基础斑点中的一个基础斑点以及在所显示的测试图案中检测到的附加斑点的子集；基于斑块中的附加斑点的子集来确定至少一个斑块在测试图案内的斑块位置，以确定用于至少一个检测到的斑点的斑点位置；基于斑点位置和至少一个检测到的斑点的检测属性来确定用于显示系统的校准参数；以及使用校准参数来对
