Embodiment 1
[0032] figure 1 It is a flow chart of a method for mapping an out-of-lock area by mobile measurement according to an embodiment of the present invention, as shown in figure 1 As shown, the method includes the following steps:
[0033] Step S102, determining the target area in the area to be drawn, and determining the preset position coordinates of the control points in the target area, wherein the target area is an unlocked area or a partially unlocked area;
[0034] Specifically, in order to lay out control points in the target area, first, you can check the topographic map of the area to be mapped, the network layout of control points and other relevant information, so as to reuse or select suitable candidate points, and then conduct on-the-spot investigations to Alternative points that meet the requirements are used for layout of measurement control points.
[0035] It should be noted that the control points should be placed in areas with a wide view, hard texture, not ea...
Embodiment 2
[0079] The embodiment of the present invention also provides a device for mobile measurement and mapping of out-of-lock areas, such as image 3 As shown, the schematic diagram of the device for mobile measurement out-of-lock area mapping includes: a determination unit 10 , an acquisition unit 20 , a processing unit 30 , an optimization unit 40 and a generation unit 50 .
[0080] The determining unit 10 is configured to determine a target area in the area to be drawn, and determine the preset position coordinates of the control points in the target area, wherein the target area is an out-of-lock area or a partially out-of-lock area. lock area;
[0081] The acquisition unit 20 is configured to acquire the original data of the target area and the position coordinates of the track points sent by the mobile measurement platform, wherein the original data is data used to draw a three-dimensional point cloud map of the target area, so The trajectory points are used to characterize t...
Embodiment 3
[0093] An electronic device provided by an embodiment of the present invention includes a memory, a processor, and a computer program stored on the memory and operable on the processor. When the processor executes the computer program, the mobile measurement unlocked area in the first embodiment above is realized. Mapping method.
[0094] Those skilled in the art can clearly understand that for the convenience and brevity of the description, the specific working process of the above-described system, device and unit can refer to the corresponding process in the foregoing method embodiment, which will not be repeated here.
