Further, when the round nail is driven or screwed into the wood, the wood fibers around the nail are compressed or partially cut, and the separated portions of the wood fibers exert pressure on the side surfaces of the nail, and when the nail is pulled out of the wood, a frictional force is generated against the side surfaces of the nail. This friction is influenced by the type, diameter and shape of the nail, as well as by the grain direction, density and moisture content of the nailed wood. When the density of the wood is larger, the abutted seam of the wood is more compact, the nail-holding force of the corresponding wood is larger, and the fixation is firmer. Meanwhile, when the round nail is nailed into the wood, the plane of the wood slightly deforms, the deformation coefficient of the wood can be obtained according to the deformation degree, if the nail holding force of the wood is strong, the deformation coefficient is small, the quality of the wood is better, and the second identification result can be corrected according to the first nail holding force information and the first deformation coefficient.

Specifically, when a first correction parameter is obtained specifically according to the first nail-holding power information and the first deformation coefficient, in order to make the obtained correction parameter more accurate and reasonable, training may be performed based on the logistic regression model coordinate system, that is, the nail-holding power information may be used as an x-axis of an abscissa and the deformation coefficient may be used as a y-axis of an ordinate to construct a logistic regression model coordinate system, and then a first identified standard regression line of the solid wood ecological plate may be obtained according to a distribution area of the acquired mass data, and first dispersed area information may be obtained on one side of the first identified standard regression line, where the first dispersed area information represents a data set of the first result, that is, when the nail-holding power is larger and the wood is smaller, the first result is that the quality identification of the first solid wood ecological plate is more excellent; on the contrary, second dispersed region information can be obtained on the other side of the first identified standard regression line, and the second dispersed region information represents a data set of the second result, namely when the nail holding power is smaller and the wood deformation is larger, the second result is that the quality identification of the first solid wood ecological plate is poor. The first nail-holding power information and the first deformation coefficient are trained on the basis of the logistic regression model coordinate system, so that the obtained correction parameters are more accurate and reasonable, and the quality identification result of the first solid wood ecological plate is more scientific and reasonable.
Further, the obtaining of the first deformation coefficient of the nail holding plane of the first solid wood ecological plate according to the first nail holding force information, step S1330 further includes:
step S1331: acquiring first nail holding plane initial image information, wherein the first nail holding plane initial image information is the plane information of the first solid wood ecological plate before nail holding;
step S1332: acquiring first plate surface flatness information according to the first nail holding plane initial image information;
step S1333: acquiring second nail holding plane image information, wherein the second nail holding plane image information is the plane information of the first solid wood ecological plate after nail holding;
step S1334: acquiring second plate surface flatness information according to the second nail holding plane image information;
step S1335: and inputting the first plate flatness information and the second plate flatness information into a time sequence prediction training set for training to obtain a first deformation coefficient of a nail holding plane of the first solid wood ecological plate.
Particularly, in order to further obtain first wood ecological plate hold nail planar first coefficient of deformation, still can obtain respectively that first nail plane initial image information holds, promptly before holding the nail the plane information of first wood ecological plate to and the nail plane image information is held to the second, promptly after holding the nail the plane information of first wood ecological plate, and then according to the contrast between the board face roughness information before holding the nail back and forth, obtain the nail planar first coefficient of deformation of holding of first wood ecological plate, in this application embodiment, can be based on the chronogenesis prediction training set carries out data training for the training result is more accurate.
Further, the embodiment of the application further comprises:
step S13351: inputting the first plate flatness information and the second plate flatness information into a time sequence prediction training set, wherein the time sequence prediction training set is obtained by training a plurality of groups of prediction data, and each group of training data in the plurality of groups of prediction data comprises: the first plate surface flatness information, the second plate surface flatness information and identification information used for identifying a prediction result of a first deformation coefficient of a nail holding plane;
step S13352: and obtaining a training result of the time sequence prediction training set, wherein the training result is a first deformation coefficient of a nail holding plane of the first solid wood ecological plate.
