The invention discloses an image target size measuring
system and a using method thereof and belongs to the technical field of target
size measurement. The measuring
system comprises a pan-tilt camera, a distance measuring module, a fixing support, a supporting bottom plate, a ruler clamping
handle, a reference ruler, a reflective tape knot and a measuring module. The calculation of the pixel sizecoefficient and the actual size of a to-be-measured target is realized based on the measuring
system, and the pixel size coefficient is calculated based on the reference ruler. A
ranging module is provided to obtain a target
object distance. Meanwhile, on the basis of providing the image information of the target, a provided
image analysis module analyzes the image information into a static picture, a provided target detection module detects the target, the
actual length, width and area of the to-be-measured target are obtained after
processing and calculation, and then the
actual length, width and area of the to-be-measured target are displayed through the provided display module. According to the invention, the technical problem of low measurement accuracy caused by the manual measurement of the target size is solved, so that the measurement of the target size is more intelligent, more accurate and more efficient.
