Abstract

The invention discloses a shielding angle real-time resolving method and system based on a digital map. The method comprises the following steps: establishing a digital map which takes a sensor site location as a center according to an action area; calculating shielding angles corresponding to different azimuth angles in the digital map; judging whether detection of sensors in every azimuth anglein the digital amp is shielded or not on the given height above sea level; acquiring the actual maximum detection distance of the sensors to the given height above sea level according to the judgmentresult; and acquiring the maximum detection distance of the sensor to a target on the basis of real-time position information of the target. The problems that calculation of the actual detection distance of the sensors at present is limited by the circumstance that terrain shielding data need to be measured in advance, calculation in real time by map data cannot be implemented, and the calculationprecision is not enough can be solved.

Description

technical field [0001] The invention relates to the field of engineering application technology, in particular to a method and system for real-time calculation of shading angles based on digital maps. Background technique [0002] At present, in engineering applications, the measured terrain shading data is mainly used to calculate the shading angle. This method is limited by the range of measurement data, lacks the ability to dynamically adjust, and cannot meet the needs of sensors for real-time shading calculations based on target positions. , pre-binding masked data makes the data accuracy constant, and cannot be flexibly customized according to usage requirements. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for real-time calculation of shading angle based on digital maps, which can solve the problem that the calculation of the actual detection distance of the current sensor is limited by the prior measuremen...
