current traditional map data acquisition, car mining, aerial photography three, but now the bike also joined the collection army. Gao de has issued a collection of bicycles, with independent GPS and high precision inertial navigation ability, to ensure that the positioning accuracy is within 5~10 meters, compared to walking acquisition can increase the acquisition efficiency of 3-4 times.
these bicycles are equipped with a 1080P camera and a wide angle 120 degree recorder, connected to the collector's smartphone. The body comes with lithium battery and mobile power, which can provide more than 10 hours of endurance for the acquisition device.
bicycle is a collection tool between step and car picking. All walking operations are likely to cause problems such as low efficiency and inaccurate positioning, while vehicle mining often causes inconvenience due to narrow roads.
