Kuelewa tofauti hii ndiko kunakowatenganisha wale wanaofaidika na kifaa hiki na wale wanaokatishwa tamaa nacho.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tepu ya kupimia ya leza hutoa mwangaza na mara ya kurudi kwake. Hii ni kipimo cha moja kwa moja na inategemea vifaa ambavyo simu nyingi za mkononi hazina. Kile ambacho simu ya mkononi hufanya ni kujenga upya jiometri ya mazingira kwa kutumia kamera na vitambuzi vya mwendo, kwa kutumia mifumo ya uhalisia ulioboreshwa \u2014 ARCore kwenye Android na ARKit kwenye iPhone \u2014 na kukadiria umbali kati ya nukta mbili ulizoweka alama.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Jinsi inavyofanya kazi ndani<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Mchakato una hatua tatu, na kila moja inaweza kushindwa:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Ugunduzi wa nukta.<\/strong> Kamera hutambua pembe, umbile, na tofauti tofauti katika eneo la tukio.<\/li>\n<li><strong>Ufuatiliaji.<\/strong> Kadri kifaa kinavyosogea, programu hufuatilia jinsi nukta hizi zinavyobadilika kwenye picha na, ikichanganya hii na data kutoka kwa kipima kasi na gyroscope, hujenga upya nafasi ya kamera angani.<\/li>\n<li><strong>Hesabu.<\/strong> Ramani yenye pande tatu ikikusanywa, umbali kati ya nukta mbili zilizowekwa alama unakuwa hesabu ya kijiometri.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Ndiyo maana programu inakuomba usogeze simu yako polepole kwa sekunde chache kabla ya kupima: hii ndiyo awamu ambayo inaunda ramani. Kuruka urekebishaji ndio sababu kuu ya matokeo mabaya.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Ni kosa kubwa sana kutarajia<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Katika hali nzuri \u2014 mwanga wa kutosha, nyuso zenye umbile, umbali wa mita chache \u2014 kupotoka kwa kawaida ni katika safu ya sentimita. Huongezeka katika hali hizi:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>masafa marefu<\/strong>, Kwa sababu hitilafu hujilimbikiza katika mchakato mzima wa ufuatiliaji.<\/li>\n<li><strong>Mwanga mdogo<\/strong>, ambayo hupunguza utambuzi wa nukta.

Kipimo kinatoka hapo \u2014 kutoka kwa nafasi inayolingana kati ya nukta mbili katika ujenzi huu mpya.<\/p>\n<p>Hii inaelezea kwa nini inafanya kazi vizuri sana katika baadhi ya hali na inashindwa katika zingine.

Kwa wale wanaopima mara kwa mara, hujilipia yenyewe kwa ununuzi wa kwanza wa vifaa, ambavyo si vingi sana wala si vidogo sana.<\/li>\n<\/ul>\n<p>Kanuni ya kidole gumba: <strong>Ikiwa nambari itaamua ukataji wa nyenzo, bajeti isiyobadilika, au agizo maalum, tumia kifaa halisi.<\/strong> Ikiwa inahitajika kwa ajili ya kuamua, kulinganisha, au kukadiria, programu hukamilisha kazi \u2014 na kuifanya vizuri.<\/p>\n\n<h2>Mipaka inayostahili kutajwa<\/h2>\n<ul>\n<li><strong>Sio mbadala wa kipimo cha tepi kwa kazi ya ujenzi.<\/strong> Useremala, uashi, na usakinishaji vinahitaji usahihi ambao ujenzi upya wa kamera hauwezi kutoa.<\/li>\n<li><strong>Haipimi kile ambacho kamera haiwezi kuona.<\/strong> Nyuma ya samani, ndani ya ukuta, juu ya dari.<\/li>\n<li><strong>Haifai kwa ajili ya uandishi wa nyaraka.<\/strong> Eneo la mali iliyoorodheshwa katika hati hiyo linatokana na utafiti uliosainiwa na mtaalamu aliyehitimu.<\/li>\n<li><strong>Haimsahihishi opereta.<\/strong> Pointi iliyotiwa alama mahali pasipofaa itazalisha nambari isiyo sahihi kwa ujasiri sawa.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Maswali Yanayoulizwa Mara kwa Mara<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Simu yangu haitafungua programu ya kipimo cha tepi. Kwa nini?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Kipimo cha uhalisia ulioboreshwa kinategemea kifaa kinachooana na ARCore kwenye Android au ARKit kwenye iPhone. Mifumo ya zamani na baadhi ya vifaa vya kiwango cha awali haviko kwenye orodha ya utangamano, na katika hali hizi programu husakinisha lakini haipimi. Njia mbadala ni kutumia programu zinazotegemea trigonometria, ambazo hufanya kazi na vitambuzi vya kawaida.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Je, simu za mkononi zenye mkanda halisi wa kupimia wa leza zipo?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Baadhi ya vifaa vya hali ya juu hujumuisha vitambuzi vya kina, kama vile LiDAR au ToF, ambavyo huboresha sana upimaji. Hata hivyo, madhumuni ya vitambuzi hivi ni kusaidia kwa umakini na uhalisia ulioboreshwa, si kuchukua nafasi ya vifaa vya upimaji\u2014na matokeo yake yanabaki kuwa makadirio.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Je, inawezekana kupima mazingira yote na kutengeneza mpango wa sakafu?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ndiyo, hivyo ndivyo programu za mpango wa sakafu zinavyofanya. Mpango uliozalishwa unaweza kutumika kuwasiliana na maseremala, wasanifu majengo, au wajenzi na kuhesabu vifaa. Hauchukui nafasi ya utafiti wa kiufundi wakati mradi unahitaji idhini rasmi au uwajibikaji.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hitimisho<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Kipimo cha tepu ya kidijitali kwenye simu yako ya mkononi ni kifaa kizuri cha kukadiria. Huondoa hitaji la kubeba vifaa, hufanya kazi kwa ajili ya kupanga ununuzi na bajeti, na hufikia sehemu ambazo kipimo cha tepu halisi hakiwezi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sio: kifaa cha usahihi. Haina vifaa vya kupimia muda wa kuruka, na mbinu ya uhalisia ulioboreshwa hukusanya makosa kutokana na umbali na ukosefu wa mwanga. Itumie kwa kupanga; thibitisha kwa kutumia kipimo cha mkanda halisi kabla ya kukata.<\/p>\n\n\n<h2>Soma pia<\/h2>\n<ul>\n<li><a href=\"https:\/\/crismob.com\/sw\/programu-ya-kupima-wanyama-kwa-kutumia-simu-yako-ya-mkononi\/\">Kupima Wanyama kwa Simu ya Mkononi: Kile Programu Inachorekodi na Inachokadiria<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/sw\/programu-ya-bure-ya-kurejesha-video-kutoka-kwa-simu-yako-ya-mkononi\/\">Kurejesha Video Kutoka kwa Simu Yako ya Mkononi: Mahali pa Kuangalia Kabla ya Kusakinisha Chochote<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/sw\/programu-za-michezo-ya-nje-ya-mtandao-cheza-popote-na-wakati-wowote-unapotaka\/\">Michezo ya Nje ya Mtandaoni kwenye Simu: Bora Zaidi ya Kucheza Bila Intaneti<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/sw\/programu-za-gps-kwa-malori\/\">GPS kwa Malori: Njia kwa Urefu na Uzito na Pale Inaposhindwa<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/sw\/programu-ya-kuondoa-virusi-kutoka-kwa-simu-yako-ya-mkononi\/\">Antivirusi kwenye simu yako: maambukizi yanatoka wapi kwenye Android na iPhone?<\/a><\/li>\n<li><a href=\"https:\/\/crismob.com\/sw\/programu-ya-kuchaji-simu-za-mkononi-kwa-kutumia-nishati-ya-jua\/\">Chaja ya jua kwa simu za mkononi: kwa nini hakuna programu inayofanya hivi?<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Existe uma diferen\u00e7a que muda tudo na hora de usar uma trena digital no celular: o aparelho n\u00e3o mede dist\u00e2ncia \u2014 ele a calcula.
