Embodiment 1

[0029]Example 1: The parking brake gear is judged

[0030]The above step 10 includes: mounting a camera on the direction of the steering wheel, establish an image pixel coordinate system, the coordinate original O is the upper point of the image, the U axis positive direction is horizontal, the V-axis positive direction is vertical downward.

[0031]Collecting the parking brake gear to separate the images of different gears each I =, and use the Mask R-CNN to identify the parking brake unit, acquire and store its boundary box R.BD Coordinate informationEstablish the gear number M frame to set the boundary box RBD-N Collection hm:

Abstract

The invention discloses a forklift truck driver practical operation examination and instruction controller gear detection method. The method comprises the steps of adjusting a camera to the position of targeting and fixing the camera, adjusting gear handles of a forklift truck to different gears, capturing corresponding gear images, using a Mask R-CNN target recognition and image segmentation framework for acquiring and storing bounding box Rbd coordinate information of the gear handles, storing images, acquired by a centroid coordinate camera of the gear handles, of the forklift truck in therunning process, acquiring and storing the coordinate information of the gear handles at the moment by using the Mask R-CNN target recognition and image segmentation framework, centroid coordinates ofthe gear handles are calculated and stored, the distances between gear coordinates and a calibration gear coordinate at the current moment is calculated, the distances is compared with one another, the gear with the smallest distance is chosen as the gear at the moment.

Description

Technical field[0001]The present invention relates to the field of practical assessment and coaching of the forklift driver, in particular, involving a controller gear detection method and system for truck driver practical assessment and coach.Background technique[0002]The forklift refers to a special mobile industrial vehicle used in specific areas such as factory plants, including balanced heavy forklifts, front-shift forklifts, side forklifts, legs forklifts, pallets and three-way stacked cars. It is widely used in a variety of handling scenes, which is the main force of logistics handling. The forklift accident will not only cause serious property damage to the equipment itself, the surrounding environment and equipment, but will often cause casualties. With the continuous rise in the amount of cargo transportation, the amount of the forklift has also increased, how to reduce the forklift accident from the source, become an urgent problem to be solved. In order to reduce the occ...
