Abstract

The application discloses an image control point structure, and belongs to the field of unmanned aerial vehicle ground fixed-point tools. The unmanned aerial vehicle image control system comprises an image control point body, a bubble level and a water bag, wherein the image control point body is provided with cross grains for unmanned aerial vehicle fixed-point marking, the water bag is arranged on the image control point body around the edges of the cross grains, and the bubble level is arranged at the center of the cross grains. The air bubble level gauge has the beneficial effects that the air bubble level gauge is arranged in the center of the cross grain, and workers can directly judge whether the image control point body is level through the air bubble level gauge when laying the air bubble level gauge. The water bag is arranged around the edge of the cross grain to form the closed counterweight ring, so that the gap between the image control point body and the ground is thoroughly blocked, strong wind is blocked from entering between the image control point body and the ground from the non-compressed area, the image control point body cannot incline, re-paving is not needed, and the operation is simple.

Description

Image control point structure Technical Field The application relates to the field of unmanned aerial vehicle ground fixed-point tools, in particular to an image control point structure. Background In the fields of unmanned aerial vehicle aerial photogrammetry, oblique photogrammetry modeling, remote sensing mapping and the like, imaging control points are key infrastructures for high-precision geographic positioning and model geometric correction. In general, the image control points are laid on the ground, and the image control points have clear and regular geometric patterns, so that aerial photographing equipment carried by the unmanned aerial vehicle can clearly identify and accurately position the center point of the aerial photographing equipment from the air. When the workman lays like the accuse point body on ground, can use the spirit level to judge earlier whether ground is level, if ground is level, the workman just can lay like the accuse point body on ground, then use the water bag to press at like four ends of accuse point and fix like the accuse point, but the water bag only covers like the accuse point four corners, like the regional not compressed tightly in accuse point body edge middle part, strong wind easily gets into like between accuse point and the ground from the area of not compressing, lead to compressing like the water bag local atress on the accuse point body, and then take place to roll, finally lead to like the inclination of accuse point body, the workman needs to reuse the spirit level to measure after the inclination of accuse point body, lay like the accuse point body again, it is too loaded down with trivial details. Disclosure of utility model The summary of the application is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. The summary of the application is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. In order to solve the technical problems mentioned in the background art section, some embodiments of the application provide an image control point structure, which comprises an image control point body, a bubble level and a water bag, wherein the image control point body is provided with cross grains for unmanned aerial vehicle fixed point marking, the water bag is arranged on the image control point body around the edges of the cross grains, and the bubble level is arranged in the center of the cross grains. Further, the image control point body is made of plastic materials. The image control point structure further comprises a fixing seat and supporting legs, wherein a convex part is arranged on one surface, away from the water bag, of the image control point body, a slot is formed in the fixing seat, the convex part is matched with the slot in shape, at least three supporting legs are arranged on the fixing seat, and the supporting legs are used for being in contact with the ground. Further, the support leg is rotatably connected with the fixing seat, and the fixing seat is provided with an accommodating area for accommodating the support leg. Further, the support leg is provided with a mounting plate, and one surface of the mounting plate facing the ground is provided with a plurality of sharp parts. Further, the support leg is detachably connected with the mounting plate. Further, an inclined surface is arranged on the fixing seat, and the supporting legs incline by 40-80 degrees relative to the ground when the supporting legs are abutted against the inclined surface. Further, at least two holding parts for holding the hand parts are arranged on the fixing base, and the holding parts are arranged on two sides of the fixing base. The application has the beneficial effects that: 1. the bubble level is arranged in the center of the cross grain, and workers can directly judge whether the image control point body is horizontal or not through the bubble level when laying the cross grain. 2. The water bag is arranged around the edge of the cross grain to form the closed counterweight ring, so that the gap between the image control point body and the ground is thoroughly blocked, strong wind is blocked from entering between the image control point body and the ground from the non-compressed area, the image control point body cannot incline, re-paving is not needed, and the operation is simple.
