Title:
LASER RADAR ANTI-INTERFERENCE METHOD AND APPARATUS, READABLE STORAGE MEDIUM, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/004629
Kind Code:
A1
Abstract:
A laser radar anti-interference method and apparatus, a computer readable storage medium, and a terminal device. The laser radar anti-interference method comprises: sequentially and respectively obtaining a first echo signal and a second echo signal of a laser radar, the first echo signal being an echo signal received by the laser radar at a kth point frequency, and the second echo signal being an echo signal received by the laser radar at a (k+1)th point frequency (S501); calculating the sum of the second echo signal and the first echo signal to obtain a third echo signal (S502); calculating an absolute value of a difference between the second echo signal and the first echo signal to obtain a fourth echo signal (S503); and calculating a difference between the third echo signal and the fourth echo signal to obtain a second echo signal after interference is filtered out (S504). The single-transmission-based anti-interference manner cannot perform filtering post-processing, but uses the correlation of the echo signals of adjacent point frequencies to filter out interference, thereby achieving an anti-interference effect.
