Recently, multi‐projective cameras (MPCs), often based on frame‐mounted multiple cameras with a small baseline and arbitrary overlap, have found a remarkable place in geomatics and vision‐based applications. This paper outlines the geometric calibration of a general MPC by presenting a mathematical model that describes its unknown generic geometry. A modified bundle block adjustment is employed to...

Since the location, human and time are three major factors in incidence of delinquency which includes drug smuggling, therefore, geographic analysis of type and amount of crimes, analysis of social and economic features of perpetrators and their residence place provide suitable opportunity for confronting and controlling abusing and drug smuggling or preventing from its perpetration. Therefore, in...

The topic of positioning in dense forest has attracted researchers' attention in the last few decades. Currently, accurate and robust positioning in complex forest environment is still not available by using standalone GNSS, and it is a major drawback for forestry automation. Laser scanning-based SLAM demonstrated its potential as an alternative positioning solution in dense boreal forest environment...

Real-time measurement of traffic parameters is increasingly demanded for monitoring the traffic status and adjusting the timings of traffic lights. In this paper, we propose an economic and operable approach to measure a traffic queue length on real-time by employing the combination of photogrammetry and image processing methods. The requirement for our development is rather simple: one camera which...

This paper proposes a supervised classification approach for the real-time pattern recognition of sows in an animal supervision system (asup). Our approach offers the possibility of the foreground subtraction in an asup’s image processing module where there is lack of statistical information regarding the background. A set of 7 farrowing sessions of sows, during day and night, have been captured (approximately...
