The invention belongs to the technical field of computer vision and thermal infrared imaging, and provides a three-dimensional imaging device with visible light and thermal infrared integrated and a calibrating method thereof. The three-dimensional imaging device with the visible light and the thermal infrared integrated comprises a double-camera holder, a support used for supporting the double-camera holder, a visible light camera and a thermal infrared camera, wherein the visible light camera and the thermal infrared camera are placed on the double-camera holder. The calibrating method comprises the following steps that calibrating is conducted on internal parameters of the visible light camera and distortion parameters of the visible light camera; calibrating is conducted on internal parameters of the thermal infrared camera and distortion parameters of the thermal infrared camera; calibrating is conducted on relative rotation and relative horizontal movement between the visible light camera and the thermal infrared camera. The three-dimensional imaging device is simple in structure and easy to calibrate and meets the requirements for three-dimensional thermal environment research and application.
