This contribution describes process which was used for verticality measurement of the bushings for laboratory construction materials in the pavilion of testing. This pavilion is newly built in VŠB-TU Ostrava, Faculty of Civil Engineering, as part of the Testing house of the building materials. The requirement of the building investor was to determine the verticality of the bushings placed between the first aboveground and the first underground floor. After the building finishing, the bushings with the diameter 70 mm will be used for loading tests of various building materials. The final number of bushings is 169, and they are placed lengthwise and crosswise in the step of 750 mm. The centres of the bushings were measured by polar method in pavilion local coordinate system. The precision of the bushing centres determination was }5 mm according to the investor´s requirement. The precision would not be followed if the standard equipment for reflector fixing was used. In that case, it was necessary to design and manufacture special tool in the shape of truncated cone. On the top part was placed central pivot for reflector with additional plate bubble.

Depth cameras play a vital role in three-dimensional (3D) shape reconstruction, machine vision, augmented/virtual reality and other visual information-related fields. However, a single depth camera cannot obtain complete information about an object by itself due to the limitation of the camera’s field of view. Multiple depth cameras can solve this problem by acquiring depth information from different viewpoints. In order to do so, they need to be calibrated to be able to accurately obtain the complete 3D information. However, traditional chessboard-based planar targets are not well suited for calibrating the relative orientations between multiple depth cameras, because the coordinates of different depth cameras need to be unified into a single coordinate system, and the multiple camera systems with a specific angle have a very small overlapping field of view. In this paper, we propose a 3D target-based multiple depth camera calibration method. Each plane of the 3D target is used to calibrate an independent depth camera. All planes of the 3D target are unified into a single coordinate system, which means the feature points on the calibration plane are also in one unified coordinate system. Using this 3D target, multiple depth cameras can be calibrated simultaneously. In this paper, a method of precise calibration using lidar is proposed. This method is not only applicable to the 3D target designed for the purposes of this paper, but it can also be applied to all 3D calibration objects consisting of planar chessboards. This method can significantly reduce the calibration error compared with traditional camera calibration methods. In addition, in order to reduce the influence of the infrared transmitter of the depth camera and improve its calibration accuracy, the calibration process of the depth camera is optimized. A series of calibration experiments were carried out, and the experimental results demonstrated the reliability and effectiveness of the proposed method.

Forest is a resources system which has prospective materials to be used for human needs. Local people within everyday life are very dependent on the natural surroundings, as well as the use of nature for human needs tend to increase. The purpose of this research is to do the analysis of vegetation and determine the potential use of non-timber forest products in Kampung Pagai, Airu District, Jayapura. The method used for the analysis of vegetation is the square plot, while the method to figure out the potential of non-timber forest adopts the method developed by Waluyo (2004). The results showed that there are at least 39 species of trees belonging to the 26 families. Regeneration of trees showed the condition which is good based on the diversity of tree species in the Sapling level, especially matoa (Pometia pinnata), kayu besi (Instia bijuga), and various plants of Ficus ssp. The potential uses of non-timber forest are also quite high. Several types of plants can be used as building materials and accessories, medicines, ornaments (including orchids), fruits, and vegetables. Key words: forest, vegetation, non-timber forest product, Airu District, Jayapura.

In the article, based on the generalization of expert practice of fingerprinting studies, the methods of falsifying traces of human papillary patterns are described. The signs displayed in the traces when using one or another method of fraud are made. The stage of the diagnostic study of fingerprint objects is described based on the examples of several expert studies from practice. As examples, the signs characterizing the transfer of traces of papillary patterns of human hands from one object to another are given. The importance of the diagnostic study during repeated fingerprint examinations is indicated. Descriptions and illustrations of comparison of signs of falsification (transfer) identified in the traces are given. An algorithm for conducting such studies and an approach to integrated assessment is described. It justifies the need for a stage of diagnostic research with the involvement of experts from other specialties (biologists, chemists, physicists, etc.) to establish the origin of the traces. According to the results of the analysis, recommendations were given regarding an integrated expert approach to the assessment of signs which were reflected in the traces identified at the research sites, and on a comprehensive assessment of the signs of the trace-receiving surface from which the traces of human papillary patterns were examined. The article also substantiates the need to develop guidelines for the diagnostic study of traces of papillary patterns of human hands to determine the method of their origin. Key words: fingerprinting, papillary patterns, falsification, artificial traces.

A fowl feather barb 10 μm in thickness was subjected to a polarized infrared spectroscopic measurement by the use of a microscopic device. Nearly 50% of its peptide groups were found to give the 1633 and 1684 cm−1 bands characteristic of the antiparallel-chain pleated sheet structure, and the remaining 50% gave the 1659 cm−1 band assignable to unordered polypeptide chains. The orientation of the pleated sheet was determined to be on average θ = 52° and χ = 39°, where θ and χ are the angles for the transformation of the XYZ coordinate system fixed on the pleated sheet and the abc coordinate system fixed on the sample barb. The Raman spectra of the barb were also examined with another microscopic device and a 488.0-nm laser beam. A sharp aa component of the Raman scattering tensor was observed at 1667 cm−1. Based on this fact, a revised set of parameters for the vibrational couplings among the peptide groups in the pleated sheet has been proposed. Some discussions have been made on the amide I Raman tensor of the antiparallel-chain pleated sheet. Key words: fowl feather barb, Raman microscope, infrared microscope, antiparallel-chain pleated sheet, Raman scattering tensor.
