Embodiment 1
[0040] A high-precision map production system based on drive test equipment, such as figure 1 ,include:
[0041] The roadside module includes a plurality of roadside units 1 for collecting road information;
[0042] The central node 2 is used to summarize the road information collected by the roadside module;
[0043] The cloud server 3 is used to receive the road information summarized by the central node, and complete the construction and update of the high-precision map;
[0044] The number of central nodes is multiple, and each central node is wirelessly connected to at least one other central node, and n is set at equal intervals along the road direction per kilometer min Roadside units, where n min Obtained by establishing a deployment cost assessment model, the calculation formula of which is:
[0045]
[0046] Where U is the cost evaluation value, p is the cost of a single roadside unit, n is the number of roadside units per kilometer of road section, S is the b...
Embodiment 2
[0057] A high-precision map production method based on road test equipment, specifically: roadside equipment is deployed on the road, and road information is transmitted to the server through the roadside equipment and the central node in sequence, so as to realize the construction and update of the overall high-precision map, each Roadside equipment includes sensors, GPS, GPRS and V2R, and sensors include lidar, millimeter wave radar and cameras.
[0058] The number of central nodes is multiple, and each central node is wirelessly connected to at least one other central node, and n is set at equal intervals along the road direction per kilometer min roadside equipment, where n min Obtained by establishing a deployment cost assessment model, the calculation formula of which is:
[0059]
[0060] Where U is the cost evaluation value, p is the cost of a single roadside equipment, n is the number of roadside equipment per kilometer of road section, S is the budgeted cost per ...
