ZVR Receives 15 Million Yuan in Houde Qianhai Pre-A Round of Financing Specializing in Large-space Optical Positioning Program

In October 2017, ZVR, a company specializing in large-space optical positioning solutions, successfully raised 15 million yuan in a pre-A funding round led by Houde Qianhai. Despite the fluctuations in the VR industry over the past few years, Guo Wei, the founder of ZVR, believes the sector has stabilized and is gradually growing. According to him, VR headset shipments have increased by over 50% year-on-year, with major players like Google, Microsoft, Facebook, and Apple continuing to invest heavily. Guo sees these efforts as "commercially successful" for building virtual reality infrastructures and solutions. ZVR introduced its multi-player infrared motion capture system called "Goku," designed for use in entertainment, education, and military simulations. The system requires 8–10 devices in a 60-square-meter space, and it can be expanded to cover thousands of square meters. It can track the 6-degree-of-freedom movement of over 100 users simultaneously. Compared to similar foreign products, Goku is priced 1/3 lower, making it a cost-effective solution for immersive VR experiences. When it comes to motion tracking and spatial positioning, various technologies such as ultrasonics, radio frequency, and computer vision are available. However, ZVR chose optics based on practicality and market trends. Unlike electromagnetic or RF systems, which can be affected by interference in complex environments, optical systems offer greater flexibility. In terms of accuracy, GPS provides meter-level precision, Wi-Fi offers tens of centimeters, while optical systems can achieve millimeter-level accuracy. Initially, ZVR developed a visible light-based motion capture system using eight cameras arranged in a circular ring. This system had centimeter-level accuracy but was limited by lighting conditions and required large, color-coded markers. It could only track three degrees of freedom—up/down, left/right, front/back—which wasn’t sufficient for larger-scale applications like a 2,000-square-meter VR theme park. To meet the demand for more realistic and interactive VR experiences, ZVR shifted from visible light to infrared technology. This transition took over a year, during which the team improved the system’s speed and added an independent computing unit to process data quickly and efficiently. By the end of 2016, ZVR officially launched the "Goku" system, which features a frame rate of 260fps, 0.1mm tracking accuracy, and a resolution of 1.3 million pixels. It can monitor up to 10 meters and supports hundreds of square meters of coverage with multiple devices. One challenge in multiplayer settings was the obstruction of markers, which affected tracking performance. To solve this, the team spent over a year researching and implementing deep learning and AI algorithms. These innovations allowed them to track the 6-degrees of freedom of limbs without relying on physical markers, significantly improving the user experience. While developing the hardware, ZVR also focused on finding the best commercial applications. Today, the company targets theme parks, education, VR townships, military simulations, and exhibitions. As of 2017, ZVR had served over 30 customers and generated sales in the tens of millions of yuan. The VR industry continues to evolve rapidly, and we will keep reporting on the latest developments in VR and AR investments. Stay tuned for more updates.
