An unevenness level inspecting device includes a target T at a known distance from a to-be-inspected surface, a traveling unit for traveling on the to-be-inspected surface, a first marker for marking information on the to-be-inspected surface, and a control unit configured to control the first marker, and the control unit calculates a height of the to-be-inspected surface at a measurement position of the target T based on three-dimensional position coordinates of the target input each time the unevenness level inspecting device travels a predetermined distance, and controls the first marker so as to mark unevenness level information indicating a difference between the height of the to-be-inspected surface and a reference height on a corresponding position on the to-be-inspected surface, and the unevenness level information is marked in a color that differs depending on a magnitude of the difference between the height of the to-be-inspected surface and the reference height.

A sensor network for measuring and processing agricultural sensor measurements having multi-depth sensors, field monitors, and/or field data collection systems. The multi-depth sensor having a GPS; sets of physical sensors located at different depths; a processing structure sampling measurements from the physical sensors; and storing the measurements. The field monitor for use with a mobile platform having: a housing; a camera; a LiDAR sensor; a processing structure capturing point data and image data; generating above-ground field data; and determining crop data. The field data collection system having a stationary field monitor and one or more mobile field monitors capturing above-ground data. The stationary field monitor and the mobile field monitors having an associated GPS. The multi-depth sensors capture below-ground data and communicating the below-ground data to the stationary field monitor. A GPU processes the above-ground data and the GPS data to generate a point cloud data set.

A stand-alone module for localizing a surveying device installed with a stand above a ground mark. The module has at least one housing attached between the stand and the surveying device, a measuring camera unit, which is arranged and designed in such a way that when the module is mounted on a stand the ground mark can be detected in the field of view of the measuring camera unit, a power supply, an inclination sensor and a communication unit.

A system includes a survey device and at least one processor. The survey device includes a support and a sensor attached to the support. The sensor is configured to capture measurement data. The at least one processor is coupled to the sensor to receive the measurement data. The at least one processor is configured to obtain a scene model corresponding to an initial set of the measurement data captured by the sensor when the support is located at an initial position, determine a location of the survey device relative to the scene model based on the initial set of the measurement data and the scene model, and update the location of the survey device relative to the scene model, based on subsequent sets of the measurement data captured by the sensor when the support is located at corresponding subsequent positions.

A system for monitoring survey reflectors arranged at a plurality of locations on an object, having: a camera, including: one or more light sources arranged to illuminate a field in space corresponding to at least 10% of a field of view of the camera, preferably the whole field of view; an image sensor receiving light beams from reflections of the beam by the survey reflectors and providing data; a body with an optical entry system, the image sensor located on a first side and the light source on a second side of the body; and a processing unit processing the data.

The processing unit is configured to determine locations of the survey reflectors from the image sensor data and detect movement of the survey reflectors based on a comparison of the determined locations with previously determined locations.

Information of an instrument point of a surveying apparatus is more simply and easily acquired. Positioning data that is obtained by a first surveying apparatus in which exterior orientation parameters are known, and positioning data that is obtained by a second surveying apparatus in which exterior orientation parameters are unknown, are received. The first surveying apparatus and the second surveying apparatus are configured to obtain positioning data by measuring multiple positions of a UAV that is flying. A piece of positioning data is acquired from the positioning data of the UAV obtained by the first surveying apparatus and from the positioning data of the UAV obtained by the second surveying apparatus. These pieces of positioning data are in a correspondence relationship. The position of the second surveying apparatus is calculated based on the pieces of positioning data that are in the correspondence relationship, by a method of resection.
