# VisionEye View Object Mapping using Ultralytics YOLOv8 🚀

## What is VisionEye Object Mapping?

[Ultralytics YOLOv8](https://github.com/ultralytics/ultralytics/) VisionEye offers the capability for computers to identify and pinpoint objects, simulating the observational precision of the human eye. This functionality enables computers to discern and focus on specific objects, much like the way the human eye observes details from a particular viewpoint.

!!! Example "VisionEye Object Mapping using YOLOv8"

    === "VisionEye Object Mapping"
        ```python

        from ultralytics import YOLO
        from ultralytics.utils.plotting import colors, Annotator

        cap = cv2.VideoCapture("path/to/video/file.mp4")
        w, h, fps = (int(cap.get(x)) for x in (cv2.CAP_PROP_FRAME_WIDTH, cv2.CAP_PROP_FRAME_HEIGHT, cv2.CAP_PROP_FPS))

        out = cv2.VideoWriter('visioneye-pinpoint.avi', cv2.VideoWriter_fourcc(*'MJPG'), fps, (w, h))

        center_point = (-10, h)

        while True:
            ret, im0 = cap.read()
            if not ret:
                print("Video frame is empty or video processing has been successfully completed.")
                break

            results = model.predict(im0)
            boxes = results[0].boxes.xyxy.cpu()
            clss = results[0].boxes.cls.cpu().tolist()

            annotator = Annotator(im0, line_width=2)

            for box, cls in zip(boxes, clss):
                annotator.box_label(box, label=names[int(cls)], color=colors(int(cls)))
                annotator.visioneye(box, center_point)

            out.write(im0)
            cv2.imshow("visioneye-pinpoint", im0)

            if cv2.waitKey(1) & 0xFF == ord('q'):
                break

        out.release()
        cap.release()
