Abstract

The invention relates to the technical field of TV tracking system simulation, in particular to a method and system for calibrating zero position of screen observation equipment. The method includes the following steps: generating a plurality of observation points on a screen, and establishing a screen with a selected point on the screen as the origin Coordinate system, determine the pixel position of the observation point of each observation point in the screen coordinate system and the observation angle parameters of each observation point observed by the observation equipment; establish the pixel position of the observation point and the observation angle parameters of each observation point. The observation matrix equation for calibrating the position parameter; according to the observation matrix equation of the observation point, the position parameter to be calibrated of the observation equipment is determined. This solution can solve the problems in the prior art that the center point of the screen observation device is manually adjusted to coincide with the center point of the screen, and the operation process is very complicated and the precision is low.

Description

technical field [0001] The invention relates to the technical field of television tracking system simulation, in particular to a method and system for calibrating zero position of screen observation equipment. Background technique [0002] For the TV tracking hardware-in-the-loop simulation test based on the TV observation equipment, the most concise method to simulate the movement of the target is to generate a virtual observation target through the projection screen, and capture the target and observe its movement through the TV equipment. In the test, the relative relationship between the TV observation equipment and the projection screen directly affects the accuracy of the observation data output. Therefore, the relative relationship needs to be calibrated before the simulation experiment. On the other hand, the imaging focus of the television observation equipment is not clearly visible, which undoubtedly greatly increases the difficulty of measuring the distance of th...
