The invention provides a high-precision positioning and posturing device and method used on laser radar platform, wherein the device main comprises: measurement photographic units, inertial measurement units and high-precision position and posture measurement and solution units. The method main comprises: obtaining air digital images through measurement photograph on the flight path of laser radar platform, then calculating air digital images relative directionally, thus obtaining low frequency high-precision posture parameters of the laser radar platform on work route; and obtaining high frequency low-precision attitude parameters of the laser radar platform through inertial measurement units; and wherein high frequency low-precision attitude parameters are amended by low frequency high-precision attitude parameters, then obtaining the laser radar platform high-precision posture parameters information. The utility of the invention can reduce the cost of high-precision position and posture measurement system, and improve the accuracy.
