Why are my Sketch Measurements Inaccurate?

Due to the nature of how the DocuSketch System operates, several factors could impact the accuracy of the Sketch. As we all know, an inaccurate Sketch can also lead to inaccuracies in the Estimate. These are common factors that cause sketch inaccuracies:

1. Incorrectly shooting a tour. The tour is always the basis for the sketch. A poorly shot tour will always result in an inaccurate sketch.

Make sure to watch out for:

• Incomplete images

• Broken images 

• Dark, blurry or hazy 360° images

• 360° images taken with a tilted camera

• The tripod and camera placed on uneven or elevated surfaces

2. Camera Height may be incorrect. It is also common for inaccurate sketches to be returned due to the incorrect camera height.

• Never place the tripod and camera on an elevated platform. In order for the DocuSketch system to accurately measure the room, it is important that the camera is standing on the same flat surface that meets the base of the walls in the room. Placing the tripod and camera on sunken or elevated surfaces will throw the measurements off.

• The camera height for the Ricoh camera should be 5' 3" from the floor to the center of the front camera lens. The camera height for the Mi camera should be 5' 0" to the center of the front camera lens. Measurements are based off of this consistent lens height and small differences here can convert into several feet on the returned sketch. This is assured when properly using the fully extended and locked DocuSketch Tripod included in the kit.
