Abstract

Способ дистанционного измерения подвижных объектов, заключающийся в проецировании с помощью импульсного источника на измеряемый объект неизменяемого во времени светового рисунка, регистрации этого рисунка фото приемным устройством за один такт съемки и передаче его на вычислительное устройство для определения координат измеряемой поверхности, отличающийся тем, что, с целью увеличения точности и надежности измерений, световой рисунок представляет собой регулярную сетку параллельных контрастных линий толщиной d и шагом D, фото приемное устройство состоит из нескольких камер, смещенных относительно источника света вдоль фиксированной оси, и производящих синхронную съемку поверхности, причем смещение первой камеры таково, что величина отклонения проекций линий для указанной камеры не превышает величины D-d, и отношение смещения каждой следующей камеры к смещению предыдущей не превышает определенной фиксированной величины, а вычислительное устройство проводит простой сравнительный анализ данных с этих камер, на основании чего определяет координаты поверхности.A method for remote measurement of moving objects, which consists in projecting a time-invariable light pattern using a pulsed source onto a measured object, registering this picture with a photo by a receiving device for one clock cycle and transmitting it to a computing device to determine the coordinates of the measured surface, characterized in that, In order to increase the accuracy and reliability of measurements, the light pattern is a regular grid of parallel contrast lines of thickness d and step D, photo receiving The device consists of several cameras displaced relative to the light source along a fixed axis, and performing simultaneous surface surveys, the offset of the first camera being such that the deviation of the projections of the lines for the specified camera does not exceed the value of Dd, and the ratio of the displacement of each subsequent camera to the displacement of the previous exceeds a certain fixed value, and the computing device performs a simple comparative analysis of data from these cameras, on the basis of which it determines the coordinates of the surface.
