“…The drawback of this approach is the error propagation when determining the sensor coefficients. Because the number of reflectance observations at a given distance is limited to four, a least squares global adjustment was chosen (7). Moreover, the adjustment was unweighted because it would involve the estimation of the a-priori radiometric error for the DN, the distance error and their cross-correlations.…”

“…The low cost of gaming sensors, along with their autonomy, portability and high acquisition framerate, have revolutionized the field of 3D documentation [1][2]. Their versatility has allowed their application in fields such as 3D object recognition [3], 3D reconstruction [4], robotics [5], and 3D thermography [6] and even other fields such as forensics [7] or unmanned aerial vehicles [8].…”

Gaming sensors have been established as low-cost sensors for the geometric reconstruction of objects. However, their radiometric capabilities remain unnoticed. Exploiting these radiometric features, several studies based on the assessment of material properties and pathological analysis could be performed using this low-cost sensor. In this paper, a reflectance-based radiometric method for the second generation of gaming sensors, Kinect 2, is presented and discussed. In particular, a repeatable methodology generalizable to different gaming sensors by means of a calibrated reference panel with Lambertian behavior is developed. The relationship between the received power and the final digital level is obtained by means of a combination of linear sensor relationship and signal attenuation, into a least squares adjustment with an outlier detector. The results confirm that the quality of the method (standard deviation better than 2% in laboratory conditions and discrepancies lower than 7% under real conditions) is valid for exploiting the radiometric possibilities of this low-cost sensor, which ranges from the pathological analysis (moisture, crusts, etc.…); to agricultural and forest resource evaluation.

“…In recent studies of forensic investigation, the use of a terrestrial laser scanner (TLS) or RG B-D camera has become a popular technique for the acquisition of 3D models of indoor crime scenes and evidence (Sansoni, 2011). The time-of-flight laser scanner, structure-light scanner and triangulation-based scanner have been used to acquire both the large-scale geometric information of crime scenes and the small-scale geometric information of evidence and victims (Ma, 2010;Holowko, 2016;Gonzalez-Jorge, 2015;Buck, 2013). These noninvasive scanners can be used to accurately generate a digital 3D scene model after registration of range images and geometric mesh processing.…”

The reconstruction of a crime scene plays an important role in digital forensic application. This article integrates computer graphics, sketch-based retrieval, and virtual reality (VR) techniques to develop a low-cost and rapid 3D crime scene presentation approach, which can be used by investigators to analyze and simulate the criminal process. First , we constructed a collection of 3D models for indoor crime scenes using various popular techniques, including laser scanning, imagebased modeling and geometric modeling. Second, to quickly obtain an object of interest from the 3D model database, a sketch-based retrieval method was proposed. Finally, a rapid modeling system that integrates our database and retrieval algorithm was developed to quickly build a digital crime scene. For practical use, an interactive real-time virtual roaming application was developed in Unity 3D and a low-cost VR head-mounted display (HMD). Practical cases have been implemented to demonstrate the feasibility and availability of our method.

“…RGB-D SLAM focuses on the use of depth sensors in SLAM pipelines. Multiple projects [5,10] focused on the first version of the Kinect (Kinect V1) for crime scene representation and object reconstruction. Kinect V1 is an RGB-D camera based on a structured-light technology that returns a dense colored point cloud.…”

In this work, we propose a method for three-dimensional (3D) reconstruction of wide crime scene, based on a Simultaneous Localization and Mapping (SLAM) approach. We used a Kinect V2 Time-of-Flight (TOF) RGB-D camera to provide colored dense point clouds at a 30 Hz frequency. This device is moved freely (6 degrees of freedom) during the scene exploration. The implemented SLAM solution aligns successive point clouds using an 3D keypoints description and matching approach. This type of approach exploits both colorimetric and geometrical information, and permits reconstruction under poor illumination conditions. Our solution has been tested for indoor crime scene and outdoor archaeological site reconstruction, returning a mean error around one centimeter. It is less precise than environmental laser scanner solution, but more practical and portable as well as less cumbersome. Also, the hardware is definitively cheaper.
