3. These marks should be easily distinguishable and have a center for the surveyors to pick up They should also be numbered so they can be easily identified in the survey data see Figure 7 2 Apply a second 2 set of 3 paint marks control points on the RIGHT face or the side wall also in a triangular shape totaling 6 control points These should also be numbered clearly 17 FIGURE 7 CONTROL POINTS Set up the Camera 1 Once you are on location a Open the carrying case b Flip the camera face down in the carrying case to keep the protective glass clean c Take the monopod and screw it into the mounting bracket on the bottom of the camera d Remove the camera from its carrying case CAE Stereo Camera Mark II is ready for use Take the photographs Important Information e CONTROL POINT IMAGES Make sure to capture the control points inside the red laser pointers which delineate the four corners of the photographs These control points must be visible within the 3D images so that they can be georeferenced e NUMBER OF IMAGES IN A ROUND There is no set number of images that have to be taken in a round You can take as little as 1 or as many as required to capture the full surface of the subject matter 18 Procedure typically 4 to 6 images Each image captured must overlap adjacent images by at least 50 ANGLE TO THE ROCK FACE Place the camera as perpendicular to the rock face as possible Be
