Title:
OPTICAL DETECTION AND DATA ACQUISITION PROCESSING APPARATUS, AND LASER RADAR AND DETECTION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/124963
Kind Code:
A1
Abstract:
A laser radar (1), comprising: a transmitting apparatus (10), the transmitting apparatus (10) being configured to emit a detection light beam for detecting an obstacle; a detection apparatus (20), comprising a plurality of detection units, each detection unit comprising a pixel array, wherein each pixel can respond to an echo reflected by the detection light beam on the obstacle and convert the echo into an electrical signal; a control apparatus (30), coupled to the transmitting apparatus (10) and the detection apparatus (20), and configured to control the transmitting apparatus (10) to emit the detection light beam, and correspondingly control one of the detection units to perform detection; and a data processing apparatus (40), coupled to the detection apparatus (20), for at least one pixel, the data processing apparatus (40) being configured to determine an echo electrical signal according to the electrical signal generated by the pixel and electrical signals generated on other pixels in the same detection unit according to the detection light beam emitted by the transmitting apparatus (10) multiple adjacent times, and determine information of the obstacle according to the echo electrical signal. The radar can implement detection of a distant small-size object, and ensures the safety of human eyes.
