Abstract

The invention discloses a solid-state area array laser radar calibration device and method based on dynamic simulation, and the device and method can meet the calibration demands of different application scenes, and achieve the multi-angle and variable-reflectivity multi-mode high-precision calibration. The solid-state area array laser radar calibration device based on dynamic simulation comprisesa high-precision scale translation table (1), a fixing frame (2), a solid-state area array laser radar (3), a calibration cylinder (4) and a calibration plate (5), the fixing frame (2) is hinged to the calibration cylinder (4) through a universal joint, and the fixing frame (2) slides on the high-precision scale translation table (1), so that the distance and the axial angle between the calibration cylinder (4) and the calibration plate (5) are changed; the solid-state area array laser radar (3) and the calibration cylinder (4) are installed and fixed in an embedded installation mode so thatthe optical path of an emitter of the solid-state area array laser radar (3) is enabled to be parallel to the axis of the calibration cylinder (4).

Description

technical field [0001] The invention belongs to the technical field of solid-state array laser radar calibration, and in particular relates to a dynamic simulation-based solid-state array laser radar calibration device and a dynamic simulation-based solid-state array laser radar calibration method. Background technique [0002] The solid-state area laser radar uses the iTOF principle for distance measurement. The measurement process is generally divided into three parts: modulated laser emission, reflected echo of the measured target, and laser echo demodulation. In the process of modulated laser emission, the quality of the spot will be different due to the changes in the transmitter power, launch angle, quantity and other parameters. Since the calibration process has high requirements for the quality of the emitter's spot, it will directly affect the distance measurement accuracy; In addition, when the modulated laser speckle is projected onto the target, the echo signal s...
