Drawing method of navigation laser monitoring factor concentration trend chart

Abstract

The invention discloses a drawing method of a navigation laser monitoring factor concentration trend chart. The method comprises the following steps that: a laser analysis module on a navigation vehicle uploads acquired monitoring factor concentration data to a navigation platform; the concentration data corresponding to each monitoring factor at each acquisition time comprise concentration valuesrespectively corresponding to the monitoring factor at the acquisition time and n dummy intervals on a vertical laser line emitted by the laser analysis module; the navigation platform takes the concentration data corresponding to two adjacent acquisition times as a concentration matrix corresponding to the monitoring factor; and the navigation platform draws a monitoring factor concentration trend chart according to the concentration matrix. According to the drawing method of the navigation laser monitoring factor concentration trend chart, the concentration values of the monitoring factorsare converted into corresponding colors according to the color concentration contrast database, and the colors corresponding to the concentration values are arranged according to the spatial distribution sequence of the timelines and the dummy intervals to form the monitoring factor concentration trend chart. Therefore, the pollution concentration condition can be visually and truly reflected.

Description

technical field [0001] The invention relates to the technical field of laser vertical detection, in particular to a method for drawing a concentration trend graph of a navigating laser monitoring factor. Background technique [0002] In the prior art, the laser analyzer on the navigation vehicle at a certain horizontal position emits a laser beam vertically from the ground to the high altitude, performs vertical scanning, and detects the concentration values ​​at each height segment. There will be a concentration value of 300 to 3000 points; for example, set the height of the height segment to 7.5m, that is, the laser scans a concentration value of 7.5 meters from the ground to the sky at a certain point, generally scanning 2250 meters to 22500 meters, and considering The navigation is real-time, and the concentration data is large. After the data is uploaded to the navigation platform, it will be uploaded from the background of the navigation platform to the front desk. T...

[0002] In the prior art, the laser analyzer on the navigation vehicle at a certain horizontal position emits a laser beam vertically from the ground to the high altitude, performs vertical scanning, and detects the concentration values ​​at each height segment. There will be a concentration value of 300 to 3000 points; for example, set the height of the height segment to 7.5m, that is, the laser scans a concentration value of 7.5 meters from the ground to the sky at a certain point, generally scanning 2250 meters to 22500 meters, and considering The navigation is real-time, and the concentration data is large. After the data is uploaded to the navigation platform, it will be uploaded from the background of the navigation platform to the front desk. The large amount of data will easily cause delays. Moreover, the direct display of the concentration data is not intuitive and cannot be clearly displayed. It is not intuitive to reflect the concentration values ​​of each monitoring factor at each location point and time point, and the trend of the concentration value of each monitoring factor over time and space is not intuitive, so it is necessary to find a method that can solve such problems
