Sonar, lidar, radar / kho qhov muag ntws

Yog li ntawd, yog tias triangulation los ntawm satellite tsis yog ib txoj hauv kev zoo los zam hauv av, cia peb sim "pom" nws ncaj qha!

Tam sim no, muaj tsawg kawg yog peb lub tswv yim npaj ua lag luam uas tuaj yeem xa cov teeb liab thiab pom tias nws yuav siv sij hawm ntev npaum li cas kom dhia: sonar, lidar thiab radar module tuaj yeem siv tau tam sim no.

Txawm li cas los xij, cov sensors no muaj qhov tsis muaj zog:

Tsis muaj zog 1: nqus

Qee qhov chaw tsuas yog tsis thaws. Cov ntaub pua tsev thiab cov ntaub pua plag nqus cov nthwv dej ultrasonic, cov xim tsaus nti absorbs lidar, thiab dej absorbs microwaves. Koj khiav tsis tau ntawm qhov koj pom tsis tau.

Tsis muaj zog 2: theem cuam tshuam

Muaj teeb liab cuam tshuam ntawm sensors. Yuav ua li cas tshwm sim thaum koj muab ntau yam zoo tib yam sensors ua ke? Koj ua li cas thiaj paub tias lub teeb liab uas koj kuaj pom yog nyob ntawm lub sensor no? Txawm hais tias ib lub sensor yuav tsum cuam tshuam nrog crosstalk los ntawm nws tus kheej thiab tos ntev txaus kom lub ncha ploj mus.

Cov teeb liab tuaj yeem raug "encoded" (qhov tseem ceeb encrypted) kom txhua lub teeb liab yog qhov tshwj xeeb, tab sis qhov no ua rau cov cuab yeej nyuaj. * * Ib qho kev daws teeb meem zoo yog los ua ib nrab ntawm cov phiaj xwm teeb liab, kom lub sijhawm yuav tsis raug kaw thiab nws yuav raug dag los ntawm cov teeb liab synchronization.

Optical flow sensor yog ib txoj kev sib txawv, uas siv lub koob yees duab los soj ntsuam seb cov khoom hauv lub lens puas loj dua (qhia tias hauv av / phab ntsa nce nrawm), me me (thaum qhov teeb meem ploj) lossis zawv zawg rau sab. Lub koob yees duab tsis cuam tshuam nrog ib leeg zoo li sonar. Yog tias koj ntse tiag tiag, koj tuaj yeem kwv yees qaij thiab lwm yam khoom 3D.

Optical flow sensors tseem muaj "absorption" tsis muaj zog. Koj xav tau qhov zoo nkauj zoo nkauj rau lawv kom pom qhov ntws, ib yam li lawv cov nas optical tsis tuaj yeem ua haujlwm ntawm iav. Lawv tau dhau los ua neeg nyiam dua, vim tias streaming suav yog tam sim no ib yam dab tsi koj tuaj yeem muab tso rau hauv FPGA lossis lub khoos phis tawj nrawm nrawm.
