Technical Field
The invention relates to the field of simulation systems, in particular to the field of tracking measurement simulation training of optical measurement equipment.
Background
The electro-optic theodolite plays an important role in the optical measurement work. In the using process of the photoelectric theodolite, a target capturing and tracking mode combining automatic television target extraction and manual operator identification is mainly adopted, and the operator captures and tracks the target level and measures the success or failure of the task of psychological quality and affairs.
To achieve a high level of operator training, a sufficient number of repetitive exercises are required. However, from the practical point of view, under the condition of limited task arrangement and expenditure, the training cost of the operator by only relying on the real task is too high, so that an economic and reasonable training mode which is close to the actual tracking measurement, is convenient to organize and develop is needed to be created, the training cost is saved, and the training efficiency is improved.
At present, simulation training systems for photoelectric theodolites are all realized by adopting a simulation method, namely, a target simulation model is established and training is carried out in a simulation environment.
Li Xinyang et al published in Changchun university of science and technology the design of simulation system for simulation training of photoelectric theodolite, which is designed mainly based on Vega Prime, wherein the functions of simulation of target motion trail, simulation of relevant parameters and special effects of a camera and the like are realized, and an objective evaluation method based on statistics of tracking results is designed. The training mode is still different from the real environment, and the combination of the assessment mode and the evaluation method with the actual use is not tight enough.
The Yao study has published Master graduate thesis design and function implementation of certain photoelectric theodolite simulation training software, and a simulation training system for the design implementation is divided into a master control server, a group control server and a client. After the client is connected with the server, the client provides an equipment operation environment in cooperation with the server, and the training purpose is achieved. The system realizes the visual simulation by establishing a simulation environment database through Photoshop and DirectX3D software. The task issuing and the concurrent training of multiple clients are realized only by utilizing a network, and a unified assessment mechanism and an evaluation method are lacked. The simulation is realized by using a simulation mode, and the simulation is different from a real environment.
