A three-dimensional location measurement sensor including first and second rotation plates to rotate about a fixed axial member independently of each other, a camera, formed inside the fixed axial member in the middle of the second rotation plate, a mirror, to be supported by a mirror supporting unit so as to be disposed over the camera, the mirror supporting unit being fixed to the first rotation plate, at least one light source, to be supported by a light source supporting unit so as to be disposed between the mirror and the second rotation plate, the light source supporting unit being fixed to the first rotation plate, a mark, to be supported by a mark supporting unit so as to be disposed between the mirror and the second rotation plate, the mark supporting unit being formed on the second rotation plate, and a gear unit, which is formed at an outer circumference of the second rotation plate and adjusts an inclination angle of the mirror. Accordingly, relatively easily determining the location of a target object by using the three-dimensional location measurement sensor is possible.

A distance measuring apparatus having dual stereo cameras includes a first stereo camera including left and right CMOS image sensors provided on one board and detecting parallax of a reference object to extract distance information, the left CMOS image sensor being spaced apart from the right CMOS image sensor at a predetermined interval, a second stereo camera separated from the first stereo camera at a predetermined distance, including left and right CMOS image sensors provided on one board, and detecting parallax of the reference object to extract distance information, the left CMOS image sensor being spaced apart from the right CMOS image sensor at a predetermined interval, and a depth map matching unit that extracts distance information on the reference object by comparing the distance information on the reference object acquired through the first stereo camera with the distance information on the reference object acquired through the second stereo camera.

The invention relates to a deep learning-based foreign object intrusion detection method for a power transmission channel. Aiming at the overhead line wire in the power transmission channel, the improved Mask-RCNN wire detection method is used to realize the semantic segmentation of the wire; the intrusion detection is performed on the distance between the wire and the foreign object At the same time, an optimized deduplication algorithm was proposed to obtain a more accurate pixel-level shape of the wire; the method of monocular distance measurement was used when the foreign object invaded, and the distance between the wire and the foreign object was obtained by converting the reference object; for the detection of foreign object intrusion in the transmission channel , adopt the method of real-time monitoring and early warning to carry out monitoring and early warning. The present invention uses the guide image for the power transmission channel to carry out guided filtering, enhances the characteristics of the target, weakens the impact caused by the weather, and improves the robustness; proposes an improved Mask R-CNN algorithm to divide the target into pixel levels, which is convenient for distance measurement; proposes a new algorithm Fit the shape of the wire and remove the weight to improve the accuracy.

A sensor utilizing an ultrasonic transducer is disclosed. The sensor includes a sending circuit module and a receiving circuit module, the sending circuit module applies a first electric drive signal including a plurality of pulses to the ultrasonic transducer, and the receiving circuit module detects the reflected wave received by the ultrasonic transducer and generates a receiving electrical signal , wherein, after applying the first electric drive signal, the transmitting circuit module applies to the ultrasonic transducer a second electric drive signal comprising a plurality of anti-phase pulses having an anti-phase relationship with the first electric drive signal, and the multiple The anti-phase pulses are controlled to apply sequentially decreasing energy from pulse to pulse to the ultrasound transducer.

The invention discloses an automatic rebar cutting device comprising a first strip-shaped base. A strip-shaped bearing case body is fixedly connected on the upper surface of the first strip-shaped base. An automatic cutting mechanism is arranged in the strip-shaped bearing case body. A moving mechanism is arranged on the lower surface of the first strip-shaped base. A discharging mechanism is arranged on the surface of the right side of the strip-shaped bearing case body.

The invention discloses an optical ranging device for an automobile. According to the device, a visual borizon reference point A is set on a front windshield of the automobile, a visual borizon reference point B is set below the windshield, the observing visual borizon is determined by judging whether a mirror point B' of the visual borizon reference point B in the windshield coincides with the visual borizon reference point A or not, and the distance between an object in the distant place and a driver is directly observed through a mirror image of a scaleplate printed or stuck on the windshield or an objective scaleplate located below the windshield in the windshield according to the similar triangle principle. The device changes visual range estimation into actual ranging, is simple, easy to operate and low in cost and can be not only independently used by serving as an automobile accessory, but also prefabricated in a naked automobile just leaving a factory.
