Transplanter seedling taking device with adjustable equidistant clamping jaws

ActiveCN224139550UApplicable to seedling removal actionImprove applicabilityTransplantingAgricultural engineeringRelative motion
The utility model discloses a transplanter seedling taking device with adjustable equidistant clamping jaws, and belongs to the technical field of transplanters. Comprising a conveying mechanism, a plurality of seedling taking clamping jaws (13) and a driving mechanism used for driving the seedling taking clamping jaws (13) to move relative to a hole tray (16), and the seedling taking clamping jaws (13) are arranged at the tail end of the driving mechanism side by side. The seedling picking device is characterized in that a distance adjusting mechanism (7) used for achieving equal-distance adjustment between any two adjacent seedling picking clamping jaws (13) is arranged at the tail end of the action of the driving mechanism, the seedling picking clamping jaws (13) are installed on the distance adjusting mechanism (7), and the side portion of the distance adjusting mechanism (7) is further connected with a distance adjusting driving unit used for driving the distance adjusting mechanism (7) to act. According to the technical scheme, equal-distance adjustment of the distance between any two of all the seedling taking clamping jaws is achieved through the distance adjusting mechanism, the seedling taking device can be more conveniently suitable for seedling taking actions of plug trays of different specifications, and the applicability is improved.

A method, device and equipment for detecting position of a track train in a turnout area, and a storage medium

ActiveCN117382703BImplement position detectionImprove reliabilityRailway signalling and safetyGratingTrackway
The application provides a method, device and equipment for detecting the position of a track in a turnout area and a storage medium, which comprises the following steps: dividing a first straight turnout, a second straight turnout and a lateral turnout to obtain a first track in a turnout area and a second track in a turnout area; the first track in a turnout area comprises the first straight turnout and the lateral turnout, and the second track in a turnout area comprises the second straight turnout and the lateral turnout; determining the first straight measurement area state of the first straight turnout, the second straight measurement area state of the second straight turnout and the lateral measurement area state of the lateral turnout based on a grating array sensing optical cable; when the first straight measurement area state or the lateral measurement area state is an occupied state, the first track state of the first track in a turnout area is an occupied state; and when the second straight measurement area state or the lateral measurement area state is an occupied state, the second track state of the second track in a turnout area is an occupied state. The application divides the jurisdiction range of the track in a turnout area, and can improve the accuracy and reliability of train positioning.

A method and system for calibrating a coordinate system using a two-point method

ActiveCN119693469Bsimple stepsReduce the number of calibrationsPattern recognitionComputer graphics (images)
This invention discloses a two-point method and system for calibrating a coordinate system. The invention sets two different types of markers at the origin and a fixed point on one coordinate axis of the transformed coordinate system. After the image acquisition device captures the image of the recognition area, it automatically identifies the markers and calculates the pixel coordinates of the origin and the fixed point. It then calculates the pixel length between the origin and the fixed point, and calculates the coordinate system transformation ratio based on the actual distance. Finally, it calculates the rotation angle parameter and constructs a coordinate system transformation matrix based on the rotation angle parameter. After the image acquisition device captures the image of the recognition area, it detects the object to be recognized and obtains the pixel coordinates of its center point. Combining the coordinate system transformation ratio and the coordinate system transformation matrix, it calculates the actual coordinates in the transformed coordinate system. This invention simplifies the steps of the hand-eye calibration method, reduces the cost of calibration plate manufacturing, and is suitable for planar image detection scenarios and detection scenarios involving objects with height.
