With the continuous development of micro-unmanned system technology, the application requirements of small, lightweight and range-measuring are put forward for the mounted vision module. First of all, this paper proposes a monocular ranging method based on small liquid lens focusing, the position of the equivalent principal plane of the imaging system and the relationship between the equivalent focal length and the voltage of the liquid lens are deduced. Then, combined with the image focusing algorithm and the Gaussian optical imaging theory, establishing a nonlinear mapping model between the distance information of the target and the control voltage value of the liquid lens. Finally, the monocular ranging experiment is designed with the optical imaging system of liquid-solid lens combination as the hardware platform. The results show that the monocular ranging error based on the liquid adjustable focus lens can be controlled within 1mm, so the method proposed in this paper is feasible and can meet the visual ranging requirements of micro-unmanned systems.
