The feature (tie point) detection algorithms are not able to recognize a dot in one image and a big coin in the other images. ![]() On the far-range images, a coin looks like a dot, and in the close-range images, the coin is seen with clear details. The mid-range shots connect the far distance loop and close-range images. Next is the mid-range and close-range shots: if the first loop is at 3m away from the object, the mid-range is at 1.5m and the close-range is about 50cm. And this “frame” will be used for alignment and depth calculation of the more close-range shots. These images give the photogrammetry software a “basic frame”. For better results, you can make more loops from different elevation levels. 36 images), where the whole object fits in the image. Good scanning practice: at least one loop around the object in 10-degree increments (approx. You should have about 3 to 5 meters of available space around the object, and for the close-up shoot, you’ll need to get to about 50cm from the object (for objects up to 3 meters in height). ![]() It is good to have enough moving space around the object you are planning to shoot.
