![]() Please refer to our How to Process Datasets guide to learn how to do so.Īdding more imagery to an existing DroneDeploy map: You can upload your set of oblique imagery with your nadir imagery to DroneDeploy. It's always good to make sure you have calibrated your compass prior to flight to avoid these issues.Įxample 3D structure workflow courtesy of GPS and 3D Models: Noisy GPS or lack of it may adversely affect your map and model.Please see here for an instructional video. Point of Interest Tool in DJI - DJI pilots can use the point of interest tool to easily generate the orbits in the diagram above.Steeper camera angles usually capture less sky which is why camera angles less than 45° are preferred (Sets 2 and 3). Oblique images stitch best if there is no sky in the background (although sometimes it is unavoidable).Oblique images stitch best if there is no sky in the background (although sometimes it is unavoidable). To improve 3D model recreation of objects with overhanging features, such as roofs, eaves, or archways, capture oblique images taken at lower altitudes and shallower angles (Set 1).One thing to remember is that obliques have a diminishing return, and if too many are taking can make it more difficult to stitch a map. When you fly the area of interest you want to take enough pictures to coat the area of interest with one coat of paint. You can think of the drone as a spray can, and the images as paint. This is achieved during manual flight by flying slower or taking photos faster. Higher overlap in both the DroneDeploy mission and oblique imagery yields higher-quality models.From this location pivot your drone in a radius around the object, capturing photos as frequently as possible.Depending on the size and surroundings of an object this camera angle or altitude may not work. Navigate the drone at this altitude and camera gimbal angle until you have the entire object you wish to model in the frame. ![]() Pilot the drone to the same altitude as the original mission but with a camera-to-ground angle of 45 degrees.When Enhanced 3D mode is turned on, Perimeter 3D mode and Crosshatch mode are combined to create the type of flight template displayed below.Įnabling Enhanced 3D Mode Best Practice to Capture Oblique ImageĬapturing oblique imagery is critical to improving the appearance and shape reconstruction of 3D models. When flying Perimeter 3D mode the drone will take images at 65 degrees down, looking towards the centroid of the map area. ![]() ![]() Scheme showing how Perimeter 3D of Enhanced 3D Mode works. For a single structure, nadir images taken from the top with just perimeter 3D are ideal. This should typically be done when one wants a good 3D model of an entire area or block as opposed to a single structure. But, in order to obtain even more obliques over your subject, you may want to add crosshatch mode. Parameter 3D Mode captures oblique images from the perimeter of your mission plan, facing towards the center of your subject and being careful not to include the horizon in the shots. Please take a look at our list of Supported Drones to determine the compatibility of your drone and DroneDeploy flight app. Any drone before the Phantom 4 will be incompatible with enhanced 3D mode. This feature is only supported for drones created after the Phantom 4. Enhanced 3D will combine parameter 3D with Crosshatch mode for optimal 3D capture. ![]()
