Abstract:

Subject of the study. A criterion for seeing objects in a low-transparency environment, the images of which are recorded by an active-pulse television measuring system. Aim of study. Experimental study of changes in the modulation contrast of objects and establishing the dependence of the accuracy of determining the range on the modulation contrast. Method. The relationship is established through a comparative analysis between the values of modulation contrast, for data with the background component subtracted from the brightness of the object image, and the accuracy indicators of range determination, such as the measurement error. Main results. The results of the work demonstrate the possibility of using the modulation contrast value to decide on the suitability of the brightness value of a detected object and to measure the distance to it in a low-transparency environment. Practical significance. The proposed visibility criterion for the presented methods of this vision system can be used as a condition for automatically determining the fact of the presence of an object for which the measurement error will be known.
