OpenCV drawing with depth
Solution 1:
This seems to be what you are asking, but it might not behave as you intend.
Create a list above of the while-loop. Also add a boolean variable (optional - see below)
rectangles = []
detected = False
while True:
When the distance is small enough, add the coordinates of the rectangle to the list - use a tuple. Use the detected
variable to prevent adding a rectangle on the same location every frame. A rectangle is only added on the first frame something is in range. Remove that code if you intend to track something across the screen.
if hight_over_table > 0:
if not detected:
detected = True
rectangles.append(((x1_bounding_box,y1_bounding_box),(x2_bounding_box,y2_bounding_box)))
else:
detected = False
print("test")
Each frame, draw all rectangles before displaying the image
for p1, p2 in rectangles:
cv2.rectangle(rgb_color_image,p1,p2,(0,255,0),3)
cv2.imshow("RGB Stream", rgb_color_image)
Note that the rectangles are drawn to the screen - not to a surface. If you point the camera to the sky, the rectangles will still be there. It is technically possible to stick the rects to a surface, but that is much more complicated.
