With the rapid development of the Internet and the further maturity of artificial intelligence, the presence of artificial intelligence can be seen everywhere in modern life. At the same time, this technology has rapidly entered the automobile industry. According to the existing technology network, the future development direction of the automobile industry is bound to make great strides towards intelligence and interconnection, and the unmanned ground vehicle（UGV）will become the main role of the automobile industry in the future. Under the guidance of this general direction, well-known traditional automobile companies and Internet giants at home and abroad have started the fierce competition of UGV, and successively developed and launched real UGV and related products. Research and development of driverless cars has emerged from the laboratories of universities and research institutes. At the same time, the strong support of relevant policies and the construction of test and demonstration areas have had a positive impact on the development of UGV, making their development speed gradually accelerate. In the tide of technology, driven by the environment, China automotive technology research center (CAC) has found a new way in the driverless research and development. Combined with the city simulation sand table, it has realized the initial control of UGV and completed the simulated driving under the test environment of UGV.
In the early stage of the entire development environment of the unmanned ground vehicle, the teacher from the automobile research center came to our Studio for a field visit. After the Demo, he was very sure to say, "this is what we want, and it will definitely meet our control requirements in the test phase. Subsequently, the NOKOV optical 3D motion capture system was determined to be used as the position tracking system in the test phase of UGV development in CAC.
Due to the simulated sand table covers an area of more than 130 square meters (motion capture systems usually use area of around 50), and the actual urban scene representation embodied in the sand, which involves many elements, the situation is complex, NOKOV engineers came to the scene, built and debug the system with the actual city sand, and increased the NOKOV motion capture professional cameras to 16, and cooperate with the truss in the city built on a sand table the whole positioning system, sufficient to cover the entire and accurate capture area.
In the process of the whole test, NOKOV motion capture positioning system got the UGV location in the sand by reflective markers, and sent the information to the server of UGV by SDK, then through the wireless module will convey the information to UGV, so as to realize real-time tracking and correct route and driving behavior. In the case of large sand table area and complex scene, NOKOV realized efficient, accurate and low-delay capture and positioning, which ensured the smooth progress of the whole unmanned initial stage test.
UGV is a kind of intelligent mobile vehicle that can replace human drivers to achieve a series of driving behaviors. It involves many research fields such as environment awareness, navigation, positioning and intelligent decision control. NOKOV will also adhere to the action guidelines of high requirements, high goals and high quality ,to escort our future UGV research and development.
