The paper represents infrared laser and digital camera-based equipment for the measurement of gap and flushness on the automobile. The system is based on the smartphone that is used as camera and database, while the red laser is targeted as a measurement tool. The method used to measure the gap and flushness is based on laser triangulation. The camera on the smartphone captures the laser line projected on the body of the automobile and serves as database of captured photos. The measurement algorithm is done on a remote computer-based algorithm that serves as computation station for gap and flushness measurement. Experiments are done on real car body in laboratory conditions. The process is done as an effective replacement of operator’s gap and flushness measurement in the production process. The results enable to eliminate the operators’ error and help to implement semi-automatic measurement system in the production plan.

Ушбу мақола инфрақизил лазер ва рақамли камера асосида автомобиль кузовидаги оралиқ масофаларни ўлчаш ускунасидан фойдаланиш таҳлилига бағишланган. Тизимнинг ажралмас қисми смартфон бўлиб, у камера ва маълумотлар базаси, инфрақизил лазер эса ўлчов воситаси сифатида ишлатилади. Оралиқ масофани ўлчаш усули лазер триангуляциясига асосланган. Смартфондаги камера автомобиль кузовига йўналтирилган лазер линиясини расмга олади ва рақамли фильтрлардан ўтказади. Ҳисоб-китоблар махсус алгоритм асосида хизмат қилувчи компьютерда бажарилади. Тажрибалар лаборатория шароитида ҳақиқий автомобил кузовида олиб борилди. Ушбу технология ишлаб чиқариш жараёнида қўлда операторлар томонидан ўлчаш учун самарали аналог сифатида ишлай олади. Олинган натижалар инсон омилини бартараф этиш ва ишлаб чиқариш жараёнида ярим автоматик ўлчаш тизимини амалга оширишга ёрдам беради.

Данная статья рассматривает применение бесконтактного оборудования на основе инфракрасного лазера и цифровой фотокамеры для измерения зазора на кузове автомобиля. Составной частью системы является смартфон, который используется в качестве камеры и базы данных, в то время как инфракрасный лазер – в качестве измерительного инструмента. Метод, используемый для измерения зазора, основан на лазерной триангуляции. Камера на смартфоне фиксирует лазерную линию, проецируемую на кузов автомобиля. Алгоритм измерения выполняется на удаленном компьютере, который служит вычислительной станцией для измерения зазора и промывки. Эксперименты проводятся на реальном кузове автомобиля в лабораторных условиях. Этот процесс является эффективной заменой ручного измерения зазора в производственном процессе. Полученные результаты позволяют исключить ошибки операторов и помогают внедрить полуавтоматическую измерительную систему в производственный процесс.
