Abstract

Abstracts in English, Zulu and TswanaCrime scene measurements are complex and seldom verified by investigators and the courts; thus, ignoring the most important feature of measurement. There is a correlational relationship between the objects, items and human intervention at the crime scene. Photogrammetry is the most accurate, reliable and error-free method of capturing crime scene measurements. Although it is a time-consuming activity, photogrammetry is highly recommended in criminal investigations and should be practiced as both a method and a technique. The contactless measurements are more accurate than the actual contact variants, which can even be calibrated in centimetres and millimetres. In this regard, 3D provides absolute certainty about crime scene measurements. The study illustrates the significance of transforming 2 Dimension photographs into more reliable 3D measurements. Naturally, ordinary photographs consist of dual dimensions, and photogrammetric intervention renders the photograph more valuable in 3 Dimension. Certainly, there is only a slight difference when photogrammetric measurements are compared to contact measurements. However, taking photographic measurements is still preferred by both private and public investigators in order to obviate later points of disputation in the courts. But, if measurements are wrong, the entire investigation will be misled. Photogrammetry is vital in reconstructing precise crime scene evidence and proper modus operandi profiling. The study aims to contribute towards more accurate and reliable crime scene measurement, which makes it to rely less on actual sketching measurements. The researcher anticipates that the introduction of photogrammetry be used in criminal investigations. Although quality comes with cost, crime investigators will gain immeasurable benefit from incorporating crime scene with photogrammetry. Credible evidence forwarded and presented in the courts should be sufficient beyond disrepute to secure convictions whose entire investigation processes were cogently within the framework of constitutional adherence and compliance. The digitalisation of the crime scene is a step forward towards the modern use of technology. The challenges of crime scene contamination contribute to a diversion of the entire investigation. Therefore, accurate photogrammetric measurements are helpful in refuting contradictory versions by witnesses and victims. Furthermore, if the MO of a crime suspect is diagnosed through false measurements of the crime scene, the entire (CJS) will focus on inappropriate processes and draw wrong conclusions due to the distortion of crime scene measurements. This research adopted the qualitative research and the sampling followed in the empirical was judgemental sampling since there is minimum available sample of participants in this more technological complex environment. Furthermore, the researcher designed and developed legend method with grid sectoral combination of multiple items measurements as the contribution of this study. The findings on the study has showed that Photogrammetry measurements are more accurate and reliable as compared to traditional measurements methods available in the market. The researcher recommended that there should be a further development and exploring of the technique in the African context.Izilinganiso zezigameko zobugebengu ziyinkimbinkimbi futhi azivamile ukuqinisekiswa ngabaphenyi nezinkantolo; ngakho, ukunganaki isici esibaluleke kakhulu sokulinganisa. Kunobudlelwano bokuhlobana phakathi kwezinto, okuthile kanye nokungenelela kwabantu endaweni yesigameko sobugebengu. Ukusetshenziswa kwezithombe ekuhloleni kuyindlela enembe kakhulu, ethembekile futhi engenaphutha ekuthwebuleni izilinganiso zendawo yesigameko sobugebengu. Nakuba kuwumsebenzi odla isikhathi, ukusetshenziswa kwezithombe ekuhloleni kuphakanyiswe kakhulu ophenyweni lobugebengu futhi kufanele kwenziwe kokubili njengendlela nesu. Izilinganiso zokungathinteki zinembe kakhulu kunezinhlobonhlobo zangempela zothintana naye, ezingalinganiswa ngisho ngamasentimitha namamilimitha. Mayelana nalokhu, i-3D ihlinzeka ngokuqiniseka okuphelele mayelana nezilinganiso zendawo yesigameko sobugebengu. Ucwaningo lubonisa ukubaluleka kokuguqula izithombe ze-2D zibe izilinganiso ezithembeke kakhulu ze-3D. Ngokwemvelo, izithombe ezijwayelekile ziqukethe ubukhulu obukabili, futhi ukungenelela kokusetshenziswa kwezithombe ekuhloleni kwenza isithombe sibe yigugu kakhulu ebukhulwini be-3D. Impela, kunomehluko omncane kuphela lapho izilinganiso zokusetshenziswa kwezithombe ekuhloleni ziqhathaniswa nezilinganiso zokuxhumana. Kodwa-ke, ukuthatha izilinganiso zezithombe kusathandwa yibo bobabili abaphenyi abazimele nabomphakathi ukuze kugwenywe amaphuzu akamuva engxabano ezinkantolo. Ukusetshenziswa kwezithombe ekuhloleni kubalulekile ekwakhiweni kabusha kobufakazi obunembayo bendawo yesigameko sobugebengu kanye nendlela efanele yokusebenza ekuqoqeni imininingwane ebulekile yomuntu noma yento. Lolu cwaningo luhlose ukufaka isandla ekulinganiseni indawo yesigameko sobugebengu enembe kakhulu, okwenza kuncishiswe ukuncika ekudwebeni kwangempela nasezilinganisweni zokuhlela. Umcwaningi ulindele ukwethulwa kokusetshenziswe kwezithombe ekuhloleni ophenyweni lobugebengu ngoba sekuvele kusetshenziswa umkhakha wobunjiniyela. Nakuba ikhwalithi iza nezindleko, abaphenyi bobugebengu bathole inzuzo engenakulinganiswa ngokuhlanganisa ukusetshenziswa kwezithombe ekuhloleni kwesehlakalo sobugebengu. Ngokulinganayo, ubufakazi obuphathekayo obudluliselwe futhi bethulwe ezinkantolo kufanele banele ngendlela engenakuphikiswa ukuze bathole ukugwetshwa kwazo zonke izinqubo zophenyo ngaphakathi kohlaka lokuhambisana nokubambelela kumthethosisekelo. Ukwenziwa kwedijithali endaweni yesigameko sobugebengu kuyisinyathelo esibheke phambili ekusetshenzisweni kwezobuchwepheshe besimanje. Izinselelo zokungcoliswa kwendawo yesigameko sobugebengu zifaka isandla ekuphambukeni kwalo lonke uphenyo. Ngakho-ke, izilinganiso ezinembile zokusetshenziswa kwezithombe ekuhloleni ziwusizo ekuphikiseni izinguqulo eziphikisanayo ngofakazi nezisulu. Ngaphezu kwalokho, indlela yokusebenza yomsolwa wobugebengu itholwa ngezilinganiso ezingamanga zendawo yesigameko sobugebengu. Lonke Uhlelo Lwezobulungiswa Bobugebengu lwenze lwagxila ezinqubweni ezingafanele futhi lwafinyelela eziphethweni ezingalungile ngenxa yokuhlanekezelwa kwezilinganiso zendawo yesigameko sobugebengu. Lolu cwaningo lwathatha ucwaningo lokuqoqa nokuhlaziya imininingwane engeyona izinombolo futhi, nendlela yencazelo yolwazi yasetshenziswa eJalimane nase-United States of America. Amasampula alandelwa yolwazi encazelweni kwaba amasampula okwahlulela njengoba kunesampula encane etholakalayo yabahlanganyeli kule ndawo eyinkimbinkimbi yobuchwepheshe. Ngaphezu kwalokho, umcwaningi wenze futhi wathuthukisa indlela edume kakhulu ngenhlanganisela yohlaka lwamabha anezikhala ahambisanayo noma awelanayo yezilinganiso zezinto eziningi njengomnikelo walolu cwaningo. Okutholwe ocwaningweni kubonise ukuthi izilinganiso zokusetshenziswa kwezithombe ekuhloleni zinembe kakhulu futhi zithembekile uma kuqhathaniswa nezindlela zokulinganisa zendabuko ezitholakala emakethe. Umcwaningi uphakamise ukuthi kuqhutshekwe nokuthuthuka futhi kuhlolwe isu lokusebenza esimeni sase-Afrika.Ditekanyetso tsa lefelo la bosenyi di marara mme ga se gantsi di tlhomamisiwa ke babatlisisi le dikgotlatshekelo; ka jalo, go ikgatholosiwa ntlha ya botlhokwa tota ya tekanyetso.
