Problems solved by technology
[0004] At present, the final output results of geophysical radar and supporting equipment are slices or cross-sections. The color of the pictures is fixed and cannot be changed; the pictures are not continuous and cannot be edited, and the analysis based on multiple pictures is very complicated. In addition, it is estimated that there is a deviation in the three-dimensional result based on the planar result. This solution is relatively fixed, and the flexibility is not high, which increases the maintenance cost.

Embodiment Construction
[0033] The spatial positioning of geophysical pulse wave data and the targeted positioning method for enhanced color matching of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.
[0034] Such as figure 1 As shown, the spatial positioning of geophysical pulse wave data and the targeted positioning method of enhanced color matching include the following steps:
[0035] Step 1. Set the elevation increase and decrease constant according to the difference between the instrument detection depth and the actual detection depth. If there is no deviation in the actual detection depth, the elevation increase and decrease constant is set to 0 meters (when the radar detection instrument is detecting, the recorded positioning depth There is a certain deviation from the actual detection depth, reading the data directly according to the detection data will lead to inaccurate depth values).
[0036] Step 2. Set t...

The invention relates to a targeted localization method for spatial localization and enhanced color matching of geophysical prospecting pulse wave data. The targeted localization method comprises the following steps of: configuring a color band file; setting an intensity interval of color matching; reading different types of radar detection data; correcting a color value, an intensity value and an elevation value of the radar data; outputting an LAS point cloud file; and outputting a point cloud color comparison table and a statistical file. According to the targeted localization method, the detection radar data intensity information is converted into the visual colored point cloud by configuring the colored tape file and setting the intensity interval needing to be enhanced and displayed, so that the visual expression of the geological radar data is enhanced, the color display of the target region is enhanced, a user can mainly check the detection result from the point cloud angle, and specific targeted positioning analysis is carried out on the point cloud data.
Description
technical field [0001] The invention belongs to the technical field of surveying, mapping and surveying, and in particular relates to a spatial positioning method for geophysical pulse wave data and a targeted positioning method for enhancing color matching. Background technique [0002] Geophysical prospecting is referred to as geophysical prospecting, which detects geological conditions such as stratum lithology and geological structure by studying and observing changes in various geophysical fields. The purpose of inferring geological properties can be achieved by measuring the distribution and change characteristics of the physical field and analyzing and studying the known geological data. [0003] The commonly used prospecting methods include gravity prospecting, magnetic prospecting, electrical prospecting, seismic prospecting, geothermal prospecting and nuclear prospecting. Transient electromagnetic data processing, after measuring line combination, curve smoothing ...
