Radar touch point fusion filtering method and system, electronic equipment and storage medium

Abstract

The invention discloses a radar touch point fusion filtering method and system, electronic equipment and a storage medium, and relates to the technical field of radar scanning, and the method comprises the steps: calculating a fusion region which linearly changes along with the radar distance for target recognition points scanned by a radar, and merging the points in the fusion region to obtain a merged fusion region; designing a touch point confidence value C which is attenuated according to time and enhanced according to change for the merging and fusing area; and when the confidence value C is greater than a fixed threshold value, determining that the target identification point belongs to a normal touch point, and when the confidence value C is less than a fixed value, determining that the target identification point is an interference point. The system comprises a merging and fusing module, a confidence value module and a judgment module. Herein, the interference generated under normal conditions can be quickly eliminated, a user is prevented from being continuously interfered by some non-real interferents, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of radar scanning, in particular to a radar touch point fusion filtering method, system, electronic equipment and storage medium. Background technique [0002] Radar is a transliteration of English Radar, derived from the abbreviation of radio detection and ranging, meaning "radio detection and ranging", that is, to use radio methods to find targets and determine their spatial positions. Therefore, radar is also called "radiolocation". Radar is an electronic device that uses electromagnetic waves to detect objects. The radar emits electromagnetic waves to irradiate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, and height.

Problems solved by technology

[0003] In practical applications, when the scanning device installed by the radar scans, the scanned area is fan-shaped, which results in more points scanned by objects closer to the device, and smaller range scanned by objects farther away from the device.

And in special cases, when the scanned wall is uneven, or there are disturbances on the scanned ground, it will cause the scanning area to continuously trigger the touch point by mistake, interfering with normal use
