Specifications Project: Integrated LIDAR, Hyperspectral, and RGB Sensor system

GENERAL INFORMATION

1.0 Scope of Work: USDA-ARS in Columbia, Missouri requires an integrated GNSS, LIDAR, Hyperspectral, and RGB Sensor system that is compliant with the National Defense Authorization Act (NDAA) and related USDA policies. The system will be used with an existing NDAA compliant USDA-ARS Unoccupied Aerial Vehicle (UAV).

2.0 Background: Modern Agricultural research relies heavily on image data from UAV mounted sensors. LIDAR (Light Detection and Ranging), Hyperspectral, and RGB (Red Green Blue) sensor systems each provide unique and important data sources for understanding how plants are growing, experiencing stress, and reacting to climate and soil variation in the field. However, examining the same plant in the field using all three sensors is very challenging if the sensors are not integrated and co-aligned. USDA-ARS in Columbia, Missouri requires an integrated LIDAR, Hyperspectral, and RGB Sensor system that is compliant with NDAA in order to achieve this.

CONTRACTOR REQUIREMENTS

3.0 Technical Requirements/Tasks: USDA-ARS in Columbia, Missouri requires an integrated GNSS, LIDAR, Hyperspectral, and RGB Sensor system that is compliant with the National Defense Authorization Act (NDAA) and related USDA policies and is attached and integrated with a FreeFly Alta X UAV currently owned by the agency. The requirements of the systems are as follows:

1) A high resolution RGB camera with at least 65MP, capable of 3FPS continuous frame rate, 9344 x 7000 or greater resolution, and integration with a survey-grade GNSS-INS.

In-situ camera calibration parameters for focal length, principal point, and distortion must be provided in addition to lever arm and boresight (position and orientation) parameters relating the camera to the GNSS-INS. Sentara 65R camera or similar.

2) LIDAR sensor with 90% or greater detection probability at 90m (10% Lambertian reflectivity 1024 @ 10 Hz), 64 channel vertical resolution, 45-degree vertical field of view, 1/10,000 false positive rate or better, < 1cm standard deviation precision at 30m.

Must be fully integrated with PPS and GPRMC messages from the GNSS-INS below.

Must also include lever arm and boresight parameters between the GNSS-INS. Ouster OS1 rev 7 or similar.

3) Hyperspectral VNIR camera with spectral range from 400-1000nm or greater, 340 or more spectral bands, 1020 spatial pixels, 5.86 micrometre pixel pitch, 6nm spectral FWHM, GigE digital interface, 250 Hz Sustained Frame Rate, 12-bit ADC depth, 480 GB solid-state storage, weight of less than 3 lbs. Fully integrated and boresight calibrated with GNSS-INS system below. Headwall VNIR Nano-HP or similar.

4) Integrated GNSS-INS system for co-alignment and direct-georeferencing of all sensors described above. Must include survey-grade multi-frequency GNSS receiver and MEMS inertial components and technology, UAV differential GNSS post-processing using a virtual reference station derived from public CORS base stations, and post-processed position accuracy of no more than 5cm. Applanix APX-15L, AV-18 Antenna, and Smartbase software or similar.

5) Integration of the complete system with a FreeFly Alta X UAV which will be provided by USDA-ARS.

6) One year or more license for processing software for orthorectification and point-cloud generation of co-aligned data from the complete system. Software stack must be capable of concurrent processing of raw GNSS-INS, RGB frame camera, line-scanning hyperspectral, and multi-beam spinning LiDAR raw data into research-ready data products such as orthomosaics, hyperspectral reflectance data cubes, point clouds, and digital surface models. Software shall enable customized workflows, output products, and processing queues to handle multi-mission processing with limited user interaction.

7) One year or more of maintenance on the system included.

8) Delivery and at least 2 days of onsite training.

9) Inclusion of three carrying cases and calibrated reflectance targets at 11, 30, and 56 % reflectance for Radiance to Reflectance data processing.

4.0 Government Furnished: USDA-ARS will provide the FreeFly Alta X UAV onto which the system will be integrated as payload.

5.0 Deliverables / Schedule: The vendor will deliver to USDA-ARS in Columbia, Missouri at 302 Curtis Hall, University of Missouri, Columbia, Missouri 65211 an integrated LIDAR, Hyperspectral, and RGB Sensor system that is compliant with the National Defense Authorization Act (NDAA) and related USDA policies and is attached and integrated with a FreeFly Alta X UAV currently owned by the agency.

6.0 Travel: The vendor will be required to travel to the site and perform two or more days of on-site training at vendor’s expense.

7.0 Contractor’s Key Personnel: N/A

8.0 Security Requirements: Vendor will NOT need access to any secure USDA IT systems, buildings, etc. Any access to standard office facilities will be with an escort at all times.

9.0 Data Rights: Vendor will not be providing any data. Data collected by the system provided by the vendor will be the property of USDA-ARS and the vendor will not have access or rights to that data except as granted for troubleshooting needs.
