Future-oriented technology meets user-friendly concepts 3D sensor system O3M Augmented reality – 3D smart camera The function principle of ifm’s PMD technology is based on time-of-flight (ToF). The scene is illuminated by modulated, invisible infrared light and the reflected light hits the PMD sensor. This sensor is also connected to the source of modulation. Each pixel of the PMD chip determines the distances to the scene due to the phase shift between the transmitted and the received signal. The integrated, active suppression of background illumination prevents saturation of the image sensor...

Systems for mobile machines IR system illumination unit Diagnostics communication Image and overlay processor Calculation 3D point cloud Sequence controller Easy set-up and handling The 3D sensor system is set up and operated via ifm’s user-friendly Vision Assistant. Its use ensures parameter setting of even complex configurations with several 3D sensor systems without profound previous knowledge. The preset wizards give support for many standard applications and intuitively guide to the best solution. At the same time the Vision Assistant enables checking of the setting in a monitoring mode...

Three-dimensional detection of scenes Automatic detection of objects 3D sensor system O3M Augmented reality – now in real 3D The PMD 3D sensor from ifm detects scenes and objects three-dimensionally with only one image capture. This avoids the motion blur that can occur with line scanners. ifm’s award-winning patented PMD technology forms the basis for a sensor system that can cope with the harsh operating conditions of mobile machines. Besides the robust and compact design the 3D sensor system is specially designed for outdoor applications with changing light conditions or bright sunlight. The...

Area surveillance in harsh environments Construction machines Intelligent collision avoidance The integrated, automatic object recognition detects up to 20 stationary or moving objects in the path of a construction vehicle. By comparing the current speed, the motion vector and fixed parameters such as the braking distance, the collision probability is calculated by the 3D sensor and transferred to the machine control system via CAN bus or Ethernet and then signalled to the driver. 3D smart camera: Integrated camera with overlay function to provide a live image and real-time warning messages....

Collision Avoidance Collision Status: Crash predicted Predicted impact velocity of collision: 2.70 m / s Predicted time to collision: 1.28 s ID of the object causing the collision: 69 Object information ID: 69 Type: Normal x1: 7.52 m delta- x: - 0.08 m y1: - 0.22 m delta-y: 1.32 m Velocity x-direction: - 3.00 m/ s Velocity y-direction: 0.00 m/ s Distance monitoring For simple distance functions the integrated distance monitoring provides up to 64 adjustable regions of interest (ROIs), i.e. individual regions whose distances are to be monitored. Rear area monitoring Construction vehicle can be...

Automation solutions for agricultural machinery For the harshest environments: Since the sensor does not have any moving components, it is virtually free of wear. Its high ambient temperature range of -40 to 85°C is the basis for universal use. Resistant to extraneous light: The PMD technology ensures high repeatability of the measured data even in difficult ambient light conditions or with direct sunlight. Communicative: Interfaces such as CAN with J1939 or CANopen and Fast Ethernet are integrated as standard. Self-diagnostic functions from the sensor to the IR system illumination unit continually...

Line guidance A highly developed algorithm with generic recognition of linear contours provides the machine driver with a selection of recognised lines and their guidance. With interrupted contours the data is interpolated. This ensures that guidance does not stop in case of smaller interruptions. An offset function ensures fine adjustment between vehicle and the line to be followed. Besides the actual line guidance, the volume flow of the harvested material can be determined at the same time so that the speed of the tractor unit or harvester can be adapted to match the quantity of material....

Collision avoidance and area surveillance Integrated camera: An additional camera in the 3D sensor system provides the machine operator with a userfriendly overview. Continuously reliable: Thanks to the specially modulated infrared light a continuously high recognition rate can be achieved even with reflective material of different intensity. All that with a minimum response time of only 40 ms. High coverage: The range of up to 15 m in typical environments and up to 35 m on reflective objects ensures universal use. Goal-oriented: Object distances and dimensions are automatically provided in a...

Area surveillance With more than 1,000 individual distance values the 3D sensor recognises objects in the detection range and signals this to the machine control system depending on the distance to the machine. Vertical drill Automatic detection of objects in the danger zone. The system is automatically stopped if something enters the monitored area. As the machine parameters are pre-selected, the 3D system is harder to bypass than conventional systems.
