“…Optical measuring systems are portable and robust, so measuring is not limited to laboratories, but it is also easily done in the field [3]. Optical measuring systems are non-contact and non-destructive and thus do not influence measured object [4]. In recent years, optical measuring systems are being intensively used in the automotive industry [1,3,5].…”

Professional paperPhotogrammetry is a technique of measuring 3D coordinates using photography as the main medium of metrology. This paper describes the use of the photogrammetric system in the automotive industry for control and measuring tasks. This contactless method is suitable for industrial application, because the measuring instruments are robust and mobile, so precise measurements are possible in production conditions. Presented results of measurements show that the optical measuring systems are powerful tools for quality control, analysis and discovering of causes of faults.

U radu je prikazana primjena fotogrametrijskog sustava na mjernim i kontrolnim zadacima u automobilskoj industriji. Ova beskontaktna metoda je pogodna jer su mjerni uređaji robusni i mobilni, pa su precizna mjerenja moguća i u proizvodnim uvjetima. Prikazani rezultati mjerenja pokazuju da su optički mjerni sustavi moćan alat za kontrolu kvalitete, analizu i otklanjanje grešaka.

Despite the efforts for precise alignment of imaging sensors and attitude sensors before launch, the accuracy of pre-launch alignment is limited. The misalignment between attitude frame and camera frame is especially important as it is related to the localization error of the spacecraft, which is one of the essential factors of satellite image quality. In this paper, a framework for camera misalignment estimation is presented with its application to a high-resolution earth-observation satellite-Deimos-2. The framework intends to provide a solution for estimation and correction of the camera misalignment of a spacecraft, covering image acquisition planning to mathematical solution of camera misalignment. Considerations for effective image acquisition planning to obtain reliable results are discussed, followed by a detailed description on a practical method for extracting many GCPs automatically using reference ortho-photos. Patterns of localization errors that commonly occur due to the camera misalignment are also investigated. A mathematical model for camera misalignment estimation is described comprehensively. The results of simulation experiments showing the validity and accuracy of the misalignment estimation model are provided. The proposed framework was applied to Deimos-2. The real-world data and results from Deimos-2 are presented.

“…The fine design of modern aircraft demands the more and more precise data of wind tunnel test, therefore, the corrections on elastic angle and elastic deformation of the test models must be taken into consideration [1][2], which require to measure the attitude and deformation of test model rather than the attitude and position of supporter used to fix the test model [4][5][6][7][8][9]. In addition, for all kinds of optical systems onboard high-speed aircraft [3], it is necessary to measure and correct aero-optics effects, such as detection systems of photoelectric imaging and the optical communication system etc, which need urgently to quantify wavefront distortion in large wind tunnel with high spatial resolution to generate the correction method.…”
