When understanding the size of objects or specimens is critical to your task, the Deep Trekker Laser Scaler is an ideal tool. Perfect for the aquaculture industry to track fish sizes, the Laser Scaler sends our two laser beams 25 mm apart from above the camera. This allows the user to scale objects within the camera view up to 2 meters away. The lasers track with the camera as it is rotated, allowing for the beams to always be viewed on screen.
How it works:
The Deep Trekker Laser Scaler provides fixed reference points 25mm apart by way of 2 laser beams. When the laser is pointed near perpendicular to an object less than 2 meters away, the two red dots are known to be 25mm apart With this aimed at a target, the user can simply make a reasonable estimate of the objects length based on how many times larger it is then the 25mm dot spread. The distance away from the camera is unimportant because both the reference dots and object scale equally. The lasers are mounted to the camera within the rov and the dots are centred on the screen. This unique setup allows the laser to scale object in the full field of view of the camera which is mounted on a 270 degree tilting arm. Measuring an object directly below or above the rov is not a problem.
