ifm O3M photoelectric 3D sensors

The waste industry is increasingly looking towards technology to improve throughputs and drive operational efficiency. With this in mind, ifm has developed a new generation of 3D Smart Sensors to further increase the automation level of mobile machines and drive operational efficiency.

Using the time-of-flight principal, the O3M photoelectric 3D sensor measures the distance between the sensor and the nearest surface point. The unit illuminates the scene with an external infrared light source and calculates the distance by means of the light reflected from the surface.

The O3M’s integrated, automatic object recognition detects up to 20 stationary or moving objects in the vehicle’s path. By comparing the current speed, the motion vector and fixed parameters, such as breaking distance, collision probability is calculated by the 3D sensor and transferred to the machine control system via CAN bus or Ethernet, before being signalled to the driver.

A highly developed algorithm from the automotive sector and a frame rate of up to 50 frames per second allows fast and reliable calculation of the 3D data. Additionally, the specially modulated infrared light enables continuously high recognition rates, even with reflective material of varied intensity.

The O3M is used in waste disposal vehicles for automatic recognition of dangerous situations such as during reversing or placing container bins.
