Yuanli Wuxian Technology has applied for a patent for an edge computing visual servo device and method, addressing the latency bottleneck associated with traditional visual servo applications at the edge. According to information from the National Intellectual Property Administration, Yuanli Wuxian Technology Holdings (Zhejiang) Co., Ltd. submitted a patent application titled “A Visual Servo Device and Method for Edge Computing,” with the publication number CN122044037A and an application date of February 2026.
The patent abstract reveals that this application discloses a visual servo device and method for edge computing, which falls within the realm of robotic visual servo technology. The method includes the following steps: synchronously acquiring a frame of image data during each control cycle; real-time tracking of preset feature points within the image data to obtain their current pixel coordinates; generating a feature point pixel error vector based on the current pixel coordinates and a predefined target pixel coordinate; and, using a hardware acceleration unit, combining a preloaded pseudo-inverse Jacobian matrix with the feature point pixel error vector through a matrix-vector multiplication operation to generate a six-degree-of-freedom pose correction vector for the robot’s end effector within a single clock cycle.
This application compresses and atomizes the high-latency software processing workflow typical of traditional visual servo systems into a core operation that can be completed in one cycle on edge computing hardware, effectively resolving the latency issue in edge applications.
According to data from Tianyancha, Yuanli Wuxian Technology Holdings (Zhejiang) Co., Ltd. was established in 2023 and is located in Hangzhou. The company primarily engages in technology promotion and application services and has a registered capital of 66,720,981.52 RMB. Analysis from Tianyancha indicates that the company has invested in 10 entities, participated in one bidding project, and holds 20 trademark registrations and 73 patent registrations, in addition to one administrative license.
