The invention discloses a device and method for testing the detection distance of an
infrared camera, and solves the technical problems that an indoor test device is large in size and an
external field test is seriously influenced by weather, and the device for testing the detection distance of the
infrared camera comprises a
collimator, an electric target wheel, a surface source
black body, an
infrared camera installation position and a control computer. An infrared camera mounting position is arranged at a preset distance away from the exit port of the
collimator; an electric target wheel is arranged at an incident port of the
collimator; the control computer is electrically connected with the electric target wheel and is used for controlling the automatic switching of a plurality of target positions of the electric target wheel, so that the target on any one of the plurality of target positions is positioned at the focal plane of the collimator; the surface source
black body is located on the side, away from the collimator, of the electric target wheel and used for irradiating the target, and the
radiation aperture of the surface source
black body completely covers the target located on the focal plane of the collimator. The control computer is connected with the surface source black body to control the temperature of the surface source black body; and the control computer is connected with the infrared camera so as to receive an
infrared image shot by the infrared camera.
