With the progress of Photoelectric theodolite's tracking performance,a lot of tracking experiment of testing and Verification for Photoelectric theodolite tracking performance and it's tracking algotithm should be carried on.The simulation technology has been widely used in Photoelectric theodolite's tracking test because of it's characteristics of low-cost,recyclable and simple experimental conditions.The degree of reproduction of the real worlds by simulation system determines the authenticity and credibility of the tracking test.In order to meet the increasing requirements of theodolite tracking and measuring,the high-realistic simulation of Photoelectric theodolite's tracking and measuring section is indispensable.To be aimed at the high-realistic simulation of Photoelectric theodolite's tracking and measuring section,the research of this article has been carried out here is:(1)Deep understanding of the working mechanism of the image-injection target tracking simulation system.By describing the imaging and tracking principle of Tracking principle and the image-injection target tracking simulation system's working principle,get to understand the simulation image workflow deeply,and the existing problems in the realistic simulation of photoelectric theodolite‘s profile measurement was analysised.(2)The modeling analysis and simulation of the characteristics of real-time target tracking dynamic mutation.Putting out high-realistic simulation of target tracking based on the imaging geometric characteristics and the real-time motion parameters of the target,analysis theodolite tracking target coordinate transformation in the imaging process with a corresponding GPU rendering pipeline space transformation,establish the target imaging geometry simulation of highly consistent.Then carry on the real-time simulation of moving objects based on measured data;the analysis of missile plume dynamic mutation characteristics through the actual image;and realize the simulation of missile's dynamic characteristics mutation using real-time variation-parameters particle system.(3)The high-realistic simulation of the target and background's infrared imaging.The photoelectric theodolite simulation for tracking applications has the demand of complex background,so the construction of tracking profile background is based on the actual image.Taking into the need to add the imaging system effect the output simulation image,accounting the status that the imaging system and related parameters of complex physical effects is difficult to obtain,carry on the simplified parameters simulation of imaging sensor to realise the engineering design of imaging sensor's simulation.(4)The verification of photoelectric theodolite tracking simulation image's fidelity.Fidelity verification of Simulation image of plays a very important role in the test results of photoelectric theodolite's tracking performance.Combined with laboratory infrared scene simulation's fidelity research,control the imaging and tracking condition of simulation images by equivalent condition with the actual image,complete the fidelity of the simulation image and the actual image in the three aspects of geometry dimension,radiation characteristics and the dynamic characteristics of the target.
